7:40 a.m.
I got upgraded to RC3 and now cannot power any VM .
Constantly getting I/O error, but checking at gluster level - I can dd from each disk or
even create a new one.
Removing the HighAvailability doesn't help.
I guess I should restore the engine from the gluster snapshot and rollback via 'yum
history undo last'.
Does anyone else have my issues ?

New subject: [ANN] oVirt 4.3.7 Third Release Candidate is now available for testing
So far,
I have rolled back the engine and the 3 hosts - still cannot manipulate the storage.It
seems that gluster itself is working, but vdsm and the oVirt stack cannot access the
storage - cannot create new VM disks, cannot start a VM and I'm on the verge of
redeploy.

New subject: [ANN] oVirt 4.3.7 Third Release Candidate is now available for testing
Hi Sahina,
Sadly engine logs have no errors.I've got only an I/O error, but in the debug of the
vdsm I can clearly see that "qemu-img" is giving an "OK".During the
upgrade I got some metadata files pending heal, but I have recovered the conflict manually
and should be OK.Today I have defined one of the VMs manually (virsh define) and then
started it , but the issue is the same.It seems to be storage-related issue,as VMs that
are on specific domain can be started , but most of my VMs are on the fast storage domains
and none of them can be started.
After the gluster snapshot restore , the engine is having issues and I have to separately
investigate that (as I poweroff my HostedEngine before creating the snapshot).
The logs can be find at
: https://drive.google.com/open?id=1VAZFZWWrpimDeVuZT0sWFVXy76scr4NM
Any ideas where to look at , as I can definitely read (using "dd if=disk" or
qemu-img info) the disks of the rhel7 VM ?

Hi Sahina,
Sadly engine logs have no errors.
I've got only an I/O error, but in the debug of the vdsm I can clearly see
that "qemu-img" is giving an "OK".
During the upgrade I got some metadata files pending heal, but I have
recovered the conflict manually and should be OK.
Today I have defined one of the VMs manually (virsh define) and then
started it , but the issue is the same.
It seems to be storage-related issue,as VMs that are on specific domain
can be started , but most of my VMs are on the fast storage domains and
none of them can be started.
After the gluster snapshot restore , the engine is having issues and I
have to separately investigate that (as I poweroff my HostedEngine before
creating the snapshot).
The logs can be find at :
https://drive.google.com/open?id=1VAZFZWWrpimDeVuZT0sWFVXy76scr4NM
Any ideas where to look at , as I can definitely read (using "dd if=disk"
or qemu-img info) the disks of the rhel7 VM ?
The vdsm logs have this:

New subject: [ANN] oVirt 4.3.7 Third Release Candidate is now available for testing
Hello All,
my engine is back online , but I'm still having difficulties to make vdsm powerup the
systems.I think that the events generated today can lead me to the right direction(just an
example , many more are there):
VDSM ovirt3.localdomain command SpmStatusVDS failed: Cannot inquire
Lease(name='SDM',
path=u'/rhev/data-center/mnt/glusterSD/gluster1:_data__fast3/ecc3bf0e-8214-45c1-98a6-0afa642e591f/dom_md/leases',
offset=1048576): (2, 'Sanlock get hosts failure', 'No such file or
directory')
I will try to collect a fresh log and see what is it complaining about this time.
Best Regards,Strahil Nikolov
Hi Sahina,
I have a strange situation:
1. When I try to access the file via 'sudo -u vdsm dd if=disk of=test bs=4M' the
command fails on aprox 60MB.
2. If I run same command as root , remove the file and then run again via vdsm user ->
this time no i/o error reported.
My guess is that I need to check what's going on the bricks
themselve ...
Best Regards,
Strahil Nikolov

Anyone got an idea why is it happening?I checked user/group and selinux permissions - all
OKI even replaced one of the disks and healed , but the result is the same for all my
VMs.

Hello All,
my engine is back online , but I'm still having difficulties to make vdsm powerup the
systems.I think that the events generated today can lead me to the right direction(just an
example , many more are there):

I will try to collect a fresh log and see what is it complaining about this time.

Hi Sahina,
I have a strange situation:
1. When I try to access the file via 'sudo -u vdsm dd if=disk of=test bs=4M' the
command fails on aprox 60MB.
2. If I run same command as root , remove the file and then run again via vdsm user ->
this time no i/o error reported.
My guess is that I need to check what's going on the bricks
themselve ...

Hi Sahina,
Sadly engine logs have no errors.I've got only an I/O error, but in the debug of the
vdsm I can clearly see that "qemu-img" is giving an "OK".During the
upgrade I got some metadata files pending heal, but I have recovered the conflict manually
and should be OK.Today I have defined one of the VMs manually (virsh define) and then
started it , but the issue is the same.It seems to be storage-related issue,as VMs that
are on specific domain can be started , but most of my VMs are on the fast storage domains
and none of them can be started.
After the gluster snapshot restore , the engine is having issues and I have to separately
investigate that (as I poweroff my HostedEngine before creating the snapshot).
The logs can be find at
: https://drive.google.com/open?id=1VAZFZWWrpimDeVuZT0sWFVXy76scr4NM
Any ideas where to look at , as I can definitely read (using "dd if=disk" or
qemu-img info) the disks of the rhel7 VM ?

So far,
I have rolled back the engine and the 3 hosts - still cannot manipulate the storage.It
seems that gluster itself is working, but vdsm and the oVirt stack cannot access the
storage - cannot create new VM disks, cannot start a VM and I'm on the verge of
redeploy.
Any errors in vdsm logs? engine logs?

I got upgraded to RC3 and now cannot power any VM .
Constantly getting I/O error, but checking at gluster level - I can dd from each disk or
even create a new one.
Removing the HighAvailability doesn't help.
I guess I should restore the engine from the gluster snapshot and rollback via 'yum
history undo last'.
Does anyone else have my issues ?

Hello,
I have a question about bugs, which are flagged as [downstream clone - 4.3.7], but are not
yet released.
I'm talking about this bug:https://bugzilla.redhat.com/show_bug.cgi?id=1749202
I can't see it in 4.3.7 release notes. Will it be included in a further release
candidate? This fix is very important I think and I can't upgrade yet because of this
bug.
Looking at the bug, the fix was done with $ git tag --contains
12bd5cb1fe7c95e29b4065fca968913722fe9eaaovirt-engine-4.3.6.6
ovirt-engine-4.3.6.7
ovirt-engine-4.3.7.0
ovirt-engine-4.3.7.1
So the fix is already included in release oVirt 4.3.6.
Sent a fix to 4.3.6 release notes: https://github.com/oVirt/ovirt-site/pull/2143. @Ryan
Barry can you please review?

Anyone got an idea why is it happening?
I checked user/group and selinux permissions - all OK
I even replaced one of the disks and healed , but the result is the same
for all my VMs.
Have you checked the permission for user/group are set correctly across all
the bricks in the cluster?
What does ls -la on the images directory from mount of the volume show you.
Adding Krutika and Rafi as they ran into a similar issue in the past.

Hello All,
my engine is back online , but I'm still having difficulties to make vdsm
powerup the systems.
I think that the events generated today can lead me to the right
direction(just an example , many more are there):
VDSM ovirt3.localdomain command SpmStatusVDS failed: Cannot inquire
Lease(name='SDM',
path=u'/rhev/data-center/mnt/glusterSD/gluster1:_data__fast3/ecc3bf0e-8214-45c1-98a6-0afa642e591f/dom_md/leases',
offset=1048576): (2, 'Sanlock get hosts failure', 'No such file or

I will try to collect a fresh log and see what is it complaining about
this time.

Hi Sahina,
Sadly engine logs have no errors.
I've got only an I/O error, but in the debug of the vdsm I can clearly see
that "qemu-img" is giving an "OK".
During the upgrade I got some metadata files pending heal, but I have
recovered the conflict manually and should be OK.
Today I have defined one of the VMs manually (virsh define) and then
started it , but the issue is the same.
It seems to be storage-related issue,as VMs that are on specific domain
can be started , but most of my VMs are on the fast storage domains and
none of them can be started.
After the gluster snapshot restore , the engine is having issues and I
have to separately investigate that (as I poweroff my HostedEngine before
creating the snapshot).
The logs can be find at :
https://drive.google.com/open?id=1VAZFZWWrpimDeVuZT0sWFVXy76scr4NM
Any ideas where to look at , as I can definitely read (using "dd if=disk"
or qemu-img info) the disks of the rhel7 VM ?
The vdsm logs have this:

So far,
I have rolled back the engine and the 3 hosts - still cannot manipulate
the storage.
It seems that gluster itself is working, but vdsm and the oVirt stack
cannot access the storage - cannot create new VM disks, cannot start a VM
and I'm on the verge of redeploy.
Any errors in vdsm logs? engine logs?

I got upgraded to RC3 and now cannot power any VM .
Constantly getting I/O error, but checking at gluster level - I can dd
from each disk or even create a new one.
Removing the HighAvailability doesn't help.
I guess I should restore the engine from the gluster snapshot and
rollback via 'yum history undo last'.
Does anyone else have my issues ?

Hello,
I have a question about bugs, which are flagged as [downstream clone -
4.3.7], but are not yet released.
I'm talking about this bug:
https://bugzilla.redhat.com/show_bug.cgi?id=1749202
I can't see it in 4.3.7 release notes. Will it be included in a further
release candidate? This fix is very important I think and I can't upgrade
yet because of this bug.
Looking at the bug, the fix was done with $ git tag --contains
12bd5cb1fe7c95e29b4065fca968913722fe9eaa
ovirt-engine-4.3.6.6
ovirt-engine-4.3.6.7
ovirt-engine-4.3.7.0
ovirt-engine-4.3.7.1
So the fix is already included in release oVirt 4.3.6.
Sent a fix to 4.3.6 release notes:
https://github.com/oVirt/ovirt-site/pull/2143. @Ryan Barry
<rbarry(a)redhat.com> can you please review?

Can you share the commands (and output) used to check this?
I would try this on the hypervisor to check what vdsm/qemu see:
$ ls -lahRZ /rhv/data-center/mnt/glusterSD/gluster-server:_path
Also, to make sure we don't have selinux issue on the hypervisor, you can
change
selinux to permissive mode:
setenforce 0
And then try again. If this was selinux issue the permission denied issue
will disappear.
If this is the case please provide the output of:
ausearh -m AVC -ts today
If the issue still exists, we eliminated selinux, and you can enable it
again:
setenforce 1
Nir
I even replaced one of the disks and healed , but the result is the
same

Anyone got an idea why is it happening?I checked user/group and selinux permissions - all
OK
Can you share the commands (and output) used to check this?I first
thought that the file is cached in memory and that's why vdsm user can read the file ,
but the following shows opposite:

As you can see , once root user reads the file -> vdsm user can also do that.
I would try this on the hypervisor to check what vdsm/qemu see:
$ ls -lahRZ /rhv/data-center/mnt/glusterSD/gluster-server:_pathI'm attaching the
output of the find I run, but this one should be enough:[root@ovirt1 ~]# find
/rhev/data-center/mnt/glusterSD/*/[0-9]*/images/ -not -user vdsm -print[root@ovirt1 ~]#
Also, to make sure we don't have selinux issue on the hypervisor,
you can change>selinux to permissive mode:
> setenforce 0
This is the first thing I did and the systems were still in permissive when I tried
again.I'm 99.99% sure it's not selinux.
And then try again. If this was selinux issue the permission denied
issue will disappear.>If this is the case please provide the output of:
>
ausearh -m AVC -ts today
If the issue still exists, we eliminated selinux, and you can enable
it again:
> setenforce 1
[root@ovirt3 ~]# ausearch -m AVC -ts today<no matches>[root@ovirt2 ~]# ausearch -m
AVC -ts today<no matches>[root@ovirt1 ~]# ausearch -m AVC -ts today<no
matches>
I have a vague feeling that the issue is related to gluster v6.5 to 6.6 upgrade which I
several days before... So if any logs are needed (or debug enabled), just mention.
Nir
I even replaced one of the disks and healed , but the result is the same for all my VMs.
Have you checked the permission for user/group are set correctly across all the bricks in
the cluster?What does ls -la on the images directory from mount of the volume show you.
Adding Krutika and Rafi as they ran into a similar issue in the past.

Hello All,
my engine is back online , but I'm still having difficulties to make vdsm powerup the
systems.I think that the events generated today can lead me to the right direction(just an
example , many more are there):
VDSM ovirt3.localdomain command SpmStatusVDS failed: Cannot inquire
Lease(name='SDM',

offset=1048576): (2, 'Sanlock get hosts failure', 'No such file or
directory')
I will try to collect a fresh log and see what is it complaining about this time.
Best Regards,Strahil Nikolov
Hi Sahina,
I have a strange situation:
1. When I try to access the file via 'sudo -u vdsm dd if=disk of=test bs=4M' the
command fails on aprox 60MB.
2. If I run same command as root , remove the file and then run again via vdsm user ->
this time no i/o error reported.
My guess is that I need to check what's going on the bricks
themselve ...
Best Regards,
Strahil Nikolov

Hi Sahina,
Sadly engine logs have no errors.I've got only an I/O error, but in the debug of the
vdsm I can clearly see that "qemu-img" is giving an "OK".During the
upgrade I got some metadata files pending heal, but I have recovered the conflict manually
and should be OK.Today I have defined one of the VMs manually (virsh define) and then
started it , but the issue is the same.It seems to be storage-related issue,as VMs that
are on specific domain can be started , but most of my VMs are on the fast storage domains
and none of them can be started.
After the gluster snapshot restore , the engine is having issues and I have to separately
investigate that (as I poweroff my HostedEngine before creating the snapshot).
The logs can be find at
: https://drive.google.com/open?id=1VAZFZWWrpimDeVuZT0sWFVXy76scr4NM
Any ideas where to look at , as I can definitely read (using "dd if=disk" or
qemu-img info) the disks of the rhel7 VM ?

Was it reset after upgrade?
Are you able to copy this file to a different location and try running a VM with this
image?
Any errors in the mount log of gluster1:_data__fast volume?

So far,
I have rolled back the engine and the 3 hosts - still cannot manipulate the storage.It
seems that gluster itself is working, but vdsm and the oVirt stack cannot access the
storage - cannot create new VM disks, cannot start a VM and I'm on the verge of
redeploy.
Any errors in vdsm logs? engine logs?

I got upgraded to RC3 and now cannot power any VM .
Constantly getting I/O error, but checking at gluster level - I can dd from each disk or
even create a new one.
Removing the HighAvailability doesn't help.
I guess I should restore the engine from the gluster snapshot and rollback via 'yum
history undo last'.
Does anyone else have my issues ?

Hello,
I have a question about bugs, which are flagged as [downstream clone - 4.3.7], but are not
yet released.
I'm talking about this bug:https://bugzilla.redhat.com/show_bug.cgi?id=1749202
I can't see it in 4.3.7 release notes. Will it be included in a further release
candidate? This fix is very important I think and I can't upgrade yet because of this
bug.
Looking at the bug, the fix was done with $ git tag --contains
12bd5cb1fe7c95e29b4065fca968913722fe9eaaovirt-engine-4.3.6.6
ovirt-engine-4.3.6.7
ovirt-engine-4.3.7.0
ovirt-engine-4.3.7.1
So the fix is already included in release oVirt 4.3.6.
Sent a fix to 4.3.6 release notes: https://github.com/oVirt/ovirt-site/pull/2143. @Ryan
Barry can you please review?

Anyone got an idea why is it happening?
I checked user/group and selinux permissions - all OK

I first thought that the file is cached in memory and that's why vdsm user
can read the file , but the following shows opposite:

As you can see , once root user reads the file -> vdsm user can also do
that.
Smells like issue on gluster side.
>I would try this on the hypervisor to check what vdsm/qemu see:
>$ ls -lahRZ /rhv/data-center/mnt/glusterSD/gluster-server:_path
I'm attaching the output of the find I run, but this one should be enough:
[root@ovirt1 ~]# find /rhev/data-center/mnt/glusterSD/*/[0-9]*/images/
-not -user vdsm -print
A full output of ls -lahRZ, showing user, group, permissions bits, and
selinux label
of the entire tree will be more useful.
>Also, to make sure we don't have selinux issue on the
hypervisor, you can
change
>selinux to permissive mode:
> setenforce 0
This is the first thing I did and the systems were still in permissive
when I tried again.I'm 99.99% sure it's not selinux.
>And then try again. If this was selinux issue the permission denied issue
will disappear.
>If this is the case please provide the output of:
> ausearh -m AVC -ts today
>If the issue still exists, we eliminated selinux, and you can enable it
again:
> setenforce 1
[root@ovirt3 ~]# ausearch -m AVC -ts today
<no matches>
[root@ovirt2 ~]# ausearch -m AVC -ts today
<no matches>
[root@ovirt1 ~]# ausearch -m AVC -ts today
<no matches>
So this is not selinux on the hypervisor. I wonder if it can be selinux on
the gluster side?
I have a vague feeling that the issue is related to gluster v6.5 to
6.6
upgrade which I several days before... So if any logs are needed (or debug
enabled), just mention.
If this is the last change, and it worked before, most likely.

New subject: [ANN] oVirt 4.3.7 Third Release Candidate is now available for testing
Hi Nir,
thanks for your feedback. My guess is that as gluster is setup to use shard - the first
one (the volume file) is OK ,but then the shard is giving an error.
As gluster1=ovirt1 and gluster2=ovirt2 & ovirt3 is the arbiter , I think it's not
SELINUX issue (all nodes are still in permissive - just to be sure that nothing comes up)
on gluster level.
As I can't powerup any VM (in the data_fastX domains), I took more radical step and
enabled Trace log on the Fuse mount and started a VM.
As per the log , I got :[2019-11-23 17:15:16.961636] W [MSGID: 114031]

This indicates that the shard 79 for gfid b0af2b81-22cf-482e-9b2f-c431b6449dae has to be
checked.
So I first check the brick logs on ovirt1 from the moment when VM was powered

P.S.: Sorry for the cyrrilic , it's my wife's laptop :). First case gives an error
and reads 67MB, while the second one works as expected.Then vdsm can access the volume
without issue (quite strange)!

Anyone got an idea why is it happening?I checked user/group and selinux permissions - all

thought that the file is cached in memory and that's why vdsm user can read the file ,
but the following shows opposite:

I would try this on the hypervisor to check what vdsm/qemu see:
$ ls -lahRZ /rhv/data-center/mnt/glusterSD/gluster-server:_pathI'm
attaching the output of the find I run, but this one should be enough:[root@ovirt1 ~]#
find /rhev/data-center/mnt/glusterSD/*/[0-9]*/images/ -not -user vdsm -print
>A full output of ls -lahRZ, showing user, group, permissions bits,
and selinux label>>of the entire tree will be more useful.

Full find of "data_fastX" domains are attached.
Also, to make sure we don't have selinux issue on the hypervisor,
you can change>selinux to permissive mode:
> setenforce 0
This is the first thing I did and the systems were still in permissive when I tried
again.I'm 99.99% sure it's not selinux.
And then try again. If this was selinux issue the permission denied
issue will disappear.>If this is the case please provide the output of:
>
ausearh -m AVC -ts today
If the issue still exists, we eliminated selinux, and you can enable
it again:
> setenforce 1
[root@ovirt3 ~]# ausearch -m AVC -ts today<no matches>[root@ovirt2 ~]# ausearch -m
AVC -ts today<no matches>[root@ovirt1 ~]# ausearch -m AVC -ts today<no
matches>
So this is not selinux on the hypervisor. I wonder if it can be
selinux on the gluster side?
I have a vague feeling that the issue is related to
gluster v6.5 to 6.6 upgrade which I several days before... So if any logs are needed (or
debug enabled), just mention.
If this is the last change, and it worked before, most likely.
Gluster was patched several days before RC3 , but all the storage-related issues
lead me to that. The strage thing is that the HostedEngine is not affected, nor the
"data" storage domain .
Any ideas appreciated. I would like to find out what has caused this instead of just
taking the shortcut to redeploy the whole setup.

Seems like it could read upto ~67MB successfully before it encountered
'Permission denied' errors. Assuming a shard-block-size of 64MB, looks like
all the shards under /.shard could not be accessed.
Could you share the following pieces of information:
1. brick logs of data_fast
2. ls -la of .shard relative to the bricks (NOT the mount) on all the
bricks of data_fast
3. and ls -la of all shards under .shard of data_fast (perhaps a handful of
them have root permission assigned somehow which is causing access to be
denied? Perhaps while resolving pending heals manually? )
-Krutika
And dd continue to read data?!
I have never seen anything like this.
It will be helpful to run this with strace:
strace -t -TT -o dd.strace dd if=vol-id of=/dev/null iflag=direct
bs=8M status=progress
And share dd.strace.
Logs in /var/log/glusterfs/exportname.log will contain useful info for
this test.

A full output of ls -lahRZ, showing user, group, permissions bits, and

So this is not selinux on the hypervisor. I wonder if it can be selinux on

Anyone got an idea why is it happening?I checked user/group and selinux permissions - all
OK
Can you share the commands (and output) used to check this?I first
thought that the file is cached in memory and that's why vdsm user can read the file ,
but the following shows opposite:

Not sure if I understood you correctly, so I ran "ls -lad
/gluster_bricks/data_fast/data_fast/.shard". If it's not what you wanted to see -
just correct me.I have run multiple "find" commands with "-exec chown

shards under .shard of data_fast (perhaps a handful of them have root permission assigned
somehow which is causing access to be denied? Perhaps while resolving pending heals
manually? )
All shards seem to be owned by "vdsm:kvm" with 660.
-Krutika
And dd continue to read data?!
I have never seen anything like this.
It will be helpful to run this with strace:
strace -t -TT -o dd.strace dd if=vol-id of=/dev/null iflag=direct bs=8M
status=progress
And share dd.strace.
Logs in /var/log/glusterfs/exportname.log will contain useful info for this test.

As you can see , once root user reads the file -> vdsm user can also do that.
Smells like issue on gluster side.
I would try this on the hypervisor to check what vdsm/qemu see:
$ ls -lahRZ /rhv/data-center/mnt/glusterSD/gluster-server:_pathI'm
attaching the output of the find I run, but this one should be enough:[root@ovirt1 ~]#
find /rhev/data-center/mnt/glusterSD/*/[0-9]*/images/ -not -user vdsm -print
A full output of ls -lahRZ, showing user, group, permissions bits, and selinux labelof the
entire tree will be more useful.
Also, to make sure we don't have selinux issue on the hypervisor,
you can change>selinux to permissive mode:
> setenforce 0
This is the first thing I did and the systems were still in permissive when I tried
again.I'm 99.99% sure it's not selinux.
And then try again. If this was selinux issue the permission denied
issue will disappear.>If this is the case please provide the output of:
>
ausearh -m AVC -ts today
If the issue still exists, we eliminated selinux, and you can enable
it again:
> setenforce 1
[root@ovirt3 ~]# ausearch -m AVC -ts today<no matches>[root@ovirt2 ~]# ausearch -m
AVC -ts today<no matches>[root@ovirt1 ~]# ausearch -m AVC -ts today<no
matches>
So this is not selinux on the hypervisor. I wonder if it can be selinux on the gluster
side?
I have a vague feeling that the issue is related to gluster v6.5 to 6.6 upgrade which I
several days before... So if any logs are needed (or debug enabled), just mention.
If this is the last change, and it worked before, most likely.

Anyone got an idea why is it happening?I checked user/group and selinux permissions - all
OK
Can you share the commands (and output) used to check this?I first
thought that the file is cached in memory and that's why vdsm user can read the file ,
but the following shows opposite:

Not sure if I understood you correctly, so I ran "ls -lad
/gluster_bricks/data_fast/data_fast/.shard". If it's not what you wanted to see -
just correct me.I have run multiple "find" commands with "-exec chown
vdsm:kvm {} \;" , just to be sure that this is not happening.>3. and ls -la of all
shards under .shard of data_fast (perhaps a handful of them have root permission assigned
somehow which is causing access to be denied? Perhaps while resolving pending heals
manually? )
All shards seem to be owned by "vdsm:kvm" with 660.

And dd continue to read data?!
I have never seen anything like this.
It will be helpful to run this with strace:
strace -t -TT -o dd.strace dd if=vol-id of=/dev/null iflag=direct bs=8M
status=progress
And share dd.strace.
Logs in /var/log/glusterfs/exportname.log will contain useful info for this test.

As you can see , once root user reads the file -> vdsm user can also do that.
Smells like issue on gluster side.
I would try this on the hypervisor to check what vdsm/qemu see:
$ ls -lahRZ /rhv/data-center/mnt/glusterSD/gluster-server:_pathI'm
attaching the output of the find I run, but this one should be enough:[root@ovirt1 ~]#
find /rhev/data-center/mnt/glusterSD/*/[0-9]*/images/ -not -user vdsm -print
A full output of ls -lahRZ, showing user, group, permissions bits, and selinux labelof the
entire tree will be more useful.
Also, to make sure we don't have selinux issue on the hypervisor,
you can change>selinux to permissive mode:
> setenforce 0
This is the first thing I did and the systems were still in permissive when I tried
again.I'm 99.99% sure it's not selinux.
And then try again. If this was selinux issue the permission denied
issue will disappear.>If this is the case please provide the output of:
>
ausearh -m AVC -ts today
If the issue still exists, we eliminated selinux, and you can enable
it again:
> setenforce 1
[root@ovirt3 ~]# ausearch -m AVC -ts today<no matches>[root@ovirt2 ~]# ausearch -m
AVC -ts today<no matches>[root@ovirt1 ~]# ausearch -m AVC -ts today<no
matches>
So this is not selinux on the hypervisor. I wonder if it can be selinux on the gluster
side?
I have a vague feeling that the issue is related to gluster v6.5 to 6.6 upgrade which I
several days before... So if any logs are needed (or debug enabled), just mention.
If this is the last change, and it worked before, most likely.

New subject: [ANN] oVirt 4.3.7 Third Release Candidate is now available for testing
Hi Nir,All,
it seems that 4.3.7 RC3 (and even RC4) are not the problem here(attached screenshot of
oVirt running on v7 gluster).It seems strange that both my serious issues with oVirt are
related to gluster issue (1st gluster v3 to v5 migration and now this one).
I have just updated to gluster v7.0 (Centos 7 repos), and rebooted all nodes.Now both
Engine and all my VMs are back online - so if you hit issues with 6.6 , you should give a
try to 7.0 (and even 7.1 is coming soon) before deciding to wipe everything.
@Krutika,
I guess you will ask for the logs, so let's switch to gluster-users about this one ?
Best Regards,Strahil Nikolov

Anyone got an idea why is it happening?I checked user/group and selinux permissions - all
OK
Can you share the commands (and output) used to check this?I first
thought that the file is cached in memory and that's why vdsm user can read the file ,
but the following shows opposite:

I would use iflag=direct instead, no need to mess with caches. Vdsm always use direct

Not sure if I understood you correctly, so I ran "ls -lad
/gluster_bricks/data_fast/data_fast/.shard". If it's not what you wanted to see -
just correct me.I have run multiple "find" commands with "-exec chown
vdsm:kvm {} \;" , just to be sure that this is not happening.>3. and ls -la of all
shards under .shard of data_fast (perhaps a handful of them have root permission assigned
somehow which is causing access to be denied? Perhaps while resolving pending heals
manually? )
All shards seem to be owned by "vdsm:kvm" with 660.

And dd continue to read data?!
I have never seen anything like this.
It will be helpful to run this with strace:
strace -t -TT -o dd.strace dd if=vol-id of=/dev/null iflag=direct bs=8M
status=progress
And share dd.strace.
Logs in /var/log/glusterfs/exportname.log will contain useful info for this test.

As you can see , once root user reads the file -> vdsm user can also do that.
Smells like issue on gluster side.
I would try this on the hypervisor to check what vdsm/qemu see:
$ ls -lahRZ /rhv/data-center/mnt/glusterSD/gluster-server:_pathI'm
attaching the output of the find I run, but this one should be enough:[root@ovirt1 ~]#
find /rhev/data-center/mnt/glusterSD/*/[0-9]*/images/ -not -user vdsm -print
A full output of ls -lahRZ, showing user, group, permissions bits, and selinux labelof the
entire tree will be more useful.
Also, to make sure we don't have selinux issue on the hypervisor,
you can change>selinux to permissive mode:
> setenforce 0
This is the first thing I did and the systems were still in permissive when I tried
again.I'm 99.99% sure it's not selinux.
And then try again. If this was selinux issue the permission denied
issue will disappear.>If this is the case please provide the output of:
>
ausearh -m AVC -ts today
If the issue still exists, we eliminated selinux, and you can enable
it again:
> setenforce 1
[root@ovirt3 ~]# ausearch -m AVC -ts today<no matches>[root@ovirt2 ~]# ausearch -m
AVC -ts today<no matches>[root@ovirt1 ~]# ausearch -m AVC -ts today<no
matches>
So this is not selinux on the hypervisor. I wonder if it can be selinux on the gluster
side?
I have a vague feeling that the issue is related to gluster v6.5 to 6.6 upgrade which I
several days before... So if any logs are needed (or debug enabled), just mention.
If this is the last change, and it worked before, most likely.

Hi Nir,All,
it seems that 4.3.7 RC3 (and even RC4) are not the problem here(attached
screenshot of oVirt running on v7 gluster).
It seems strange that both my serious issues with oVirt are related to
gluster issue (1st gluster v3 to v5 migration and now this one).
I have just updated to gluster v7.0 (Centos 7 repos), and rebooted all
nodes.
Now both Engine and all my VMs are back online - so if you hit issues with
6.6 , you should give a try to 7.0 (and even 7.1 is coming soon) before
deciding to wipe everything.
@Krutika,
I guess you will ask for the logs, so let's switch to gluster-users about
this one ?
Best Regards,
Strahil Nikolov

Anyone got an idea why is it happening?
I checked user/group and selinux permissions - all OK

I first thought that the file is cached in memory and that's why vdsm user
can read the file , but the following shows opposite:

Not sure if I understood you correctly, so I ran "ls -lad
/gluster_bricks/data_fast/data_fast/.shard". If it's not what you wanted to
see - just correct me.
I have run multiple "find" commands with "-exec chown vdsm:kvm {} \;"
,
just to be sure that this is not happening.
>3. and ls -la of all shards under .shard of data_fast (perhaps a handful
of them have root permission assigned somehow which is causing access to be
denied? Perhaps while resolving pending heals manually? )
All shards seem to be owned by "vdsm:kvm" with 660.
-Krutika
And dd continue to read data?!
I have never seen anything like this.
It will be helpful to run this with strace:
strace -t -TT -o dd.strace dd if=vol-id of=/dev/null iflag=direct
bs=8M status=progress
And share dd.strace.
Logs in /var/log/glusterfs/exportname.log will contain useful info for
this test.

As you can see , once root user reads the file -> vdsm user can also do
that.
Smells like issue on gluster side.
>I would try this on the hypervisor to check what vdsm/qemu see:
>$ ls -lahRZ /rhv/data-center/mnt/glusterSD/gluster-server:_path
I'm attaching the output of the find I run, but this one should be enough:
[root@ovirt1 ~]# find /rhev/data-center/mnt/glusterSD/*/[0-9]*/images/
-not -user vdsm -print
A full output of ls -lahRZ, showing user, group, permissions bits, and
selinux label
of the entire tree will be more useful.
>Also, to make sure we don't have selinux issue on the hypervisor, you can
change

This is the first thing I did and the systems were still in permissive
when I tried again.I'm 99.99% sure it's not selinux.
>And then try again. If this was selinux issue the permission denied issue
will disappear.

[root@ovirt3 ~]# ausearch -m AVC -ts today
<no matches>
[root@ovirt2 ~]# ausearch -m AVC -ts today
<no matches>
[root@ovirt1 ~]# ausearch -m AVC -ts today
<no matches>
So this is not selinux on the hypervisor. I wonder if it can be selinux on
the gluster side?
I have a vague feeling that the issue is related to gluster v6.5 to 6.6
upgrade which I several days before... So if any logs are needed (or debug
enabled), just mention.
If this is the last change, and it worked before, most likely.

New subject: [ANN] oVirt 4.3.7 Third Release Candidate is now available for testing
Hi Krutika,
Apparently, in context acl info got corrupted see brick logs
[posix-acl.c:263:posix_acl_log_permit_denied] 0-data_fast-access-control:
client:
CTX_ID:dae9ffad-6acd-4a43-9372-229a3018fde9-GRAPH_ID:0-PID:11468-HOST:ovirt2.localdomain-PC_NAME:data_fast-client-0-RECON_NO:-0,

req(uid:107,gid:107,perm:1,ngrps:4),
ctx(uid:0,gid:0,in-groups:0,perm:000,updated-fop:INVALID, acl:-)
[Permission denied]
which resulted in the situation. There was one bug similar was reported
https://bugzilla.redhat.com/show_bug.cgi?id=1668286 and
it got fixed in 6.6 release IMO https://review.gluster.org/#/c/glusterfs/+/23233/. But
here he mentioned he saw the issue when
he upgraded from 6.5 to 6.6
One way to workaround is to perform a dummy setfacl(preferably using root) on the
corrupted files which will forcefully fetch the acl
info again from backend and update the context. Another approach to restart brick
process(kill and vol start force)

Jiffin

Sorry about the late response.
I looked at the logs. These errors are originating from posix-acl

Hi Nir,All,
it seems that 4.3.7 RC3 (and even RC4) are not the problem here(attached
screenshot of oVirt running on v7 gluster).
It seems strange that both my serious issues with oVirt are related to
gluster issue (1st gluster v3 to v5 migration and now this one).
I have just updated to gluster v7.0 (Centos 7 repos), and rebooted all
nodes.
Now both Engine and all my VMs are back online - so if you hit issues with
6.6 , you should give a try to 7.0 (and even 7.1 is coming soon) before
deciding to wipe everything.
@Krutika,
I guess you will ask for the logs, so let's switch to gluster-users about
this one ?
Best Regards,
Strahil Nikolov

Anyone got an idea why is it happening?
I checked user/group and selinux permissions - all OK

I first thought that the file is cached in memory and that's why vdsm user
can read the file , but the following shows opposite:

Not sure if I understood you correctly, so I ran "ls -lad
/gluster_bricks/data_fast/data_fast/.shard". If it's not what you wanted to
see - just correct me.
I have run multiple "find" commands with "-exec chown vdsm:kvm {} \;"
,
just to be sure that this is not happening.
>3. and ls -la of all shards under .shard of data_fast (perhaps a handful
of them have root permission assigned somehow which is causing access to be

All shards seem to be owned by "vdsm:kvm" with 660.

And dd continue to read data?!
I have never seen anything like this.
It will be helpful to run this with strace:
strace -t -TT -o dd.strace dd if=vol-id of=/dev/null iflag=direct
bs=8M status=progress
And share dd.strace.
Logs in /var/log/glusterfs/exportname.log will contain useful info for
this test.

As you can see , once root user reads the file -> vdsm user can also do
that.
Smells like issue on gluster side.
>I would try this on the hypervisor to check what vdsm/qemu see:
>$ ls -lahRZ /rhv/data-center/mnt/glusterSD/gluster-server:_path
I'm attaching the output of the find I run, but this one should be enough:
[root@ovirt1 ~]# find /rhev/data-center/mnt/glusterSD/*/[0-9]*/images/
-not -user vdsm -print
A full output of ls -lahRZ, showing user, group, permissions bits, and
selinux label
of the entire tree will be more useful.
>Also, to make sure we don't have selinux issue on the hypervisor, you can
change
>selinux to permissive mode:
> setenforce 0
This is the first thing I did and the systems were still in permissive
when I tried again.I'm 99.99% sure it's not selinux.
>And then try again. If this was selinux issue the permission denied issue
will disappear.
>If this is the case please provide the output of:
> ausearh -m AVC -ts today
>If the issue still exists, we eliminated selinux, and you can enable it
again:
> setenforce 1
[root@ovirt3 ~]# ausearch -m AVC -ts today
<no matches>
[root@ovirt2 ~]# ausearch -m AVC -ts today
<no matches>
[root@ovirt1 ~]# ausearch -m AVC -ts today
<no matches>
So this is not selinux on the hypervisor. I wonder if it can be selinux on
the gluster side?
I have a vague feeling that the issue is related to gluster v6.5 to 6.6
upgrade which I several days before... So if any logs are needed (or debug
enabled), just mention.
If this is the last change, and it worked before, most likely.

Are you sure it's fixed?If yes, then this looks like a regresion.
By the way, I'm not using ACL - how can I permanently disable it ,so even if ACL gets
corrupted -> my oVirt will survive ?
Thanks in advance for your answer.

Hi Krutika,
Apparently, in context acl info got corrupted see brick logs

which resulted in the situation. There was one bug similar was reported
https://bugzilla.redhat.com/show_bug.cgi?id=1668286 and
it got fixed in 6.6 release IMO https://review.gluster.org/#/c/glusterfs/+/23233/. But
here he mentioned he saw the issue when
he upgraded from 6.5 to 6.6
One way to workaround is to perform a dummy setfacl(preferably using root) on the
corrupted files which will forcefully fetch the acl
info again from backend and update the context. Another approach to restart brick
process(kill and vol start force)

Hi Nir,All,
it seems that 4.3.7 RC3 (and even RC4) are not the problem here(attached
screenshot of oVirt running on v7 gluster).
It seems strange that both my serious issues with oVirt are related to
gluster issue (1st gluster v3 to v5 migration and now this one).
I have just updated to gluster v7.0 (Centos 7 repos), and rebooted all
nodes.
Now both Engine and all my VMs are back online - so if you hit issues with
6.6 , you should give a try to 7.0 (and even 7.1 is coming soon) before
deciding to wipe everything.
@Krutika,
I guess you will ask for the logs, so let's switch to gluster-users about
this one ?

Anyone got an idea why is it happening?
I checked user/group and selinux permissions - all OK
>Can you share the commands (and output) used to check this?
I first thought that the file is cached in memory and that's why vdsm user
can read the file , but the following shows opposite:

Not sure if I understood you correctly, so I ran "ls -lad
/gluster_bricks/data_fast/data_fast/.shard". If it's not what you wanted to
see - just correct me.
I have run multiple "find" commands with "-exec chown vdsm:kvm {} \;"
,
just to be sure that this is not happening.
>3. and ls -la of all shards under .shard of data_fast (perhaps a handful
of them have root permission assigned somehow which is causing access to be
denied? Perhaps while resolving pending heals manually? )
All shards seem to be owned by "vdsm:kvm" with 660.
-Krutika
And dd continue to read data?!
I have never seen anything like this.
It will be helpful to run this with strace:
strace -t -TT -o dd.strace dd if=vol-id of=/dev/null iflag=direct
bs=8M status=progress
And share dd.strace.
Logs in /var/log/glusterfs/exportname.log will contain useful info for
this test.

As you can see , once root user reads the file -> vdsm user can also do
that.
Smells like issue on gluster side.
>I would try this on the hypervisor to check what vdsm/qemu see:
>$ ls -lahRZ /rhv/data-center/mnt/glusterSD/gluster-server:_path
I'm attaching the output of the find I run, but this one should be enough:
[root@ovirt1 ~]# find /rhev/data-center/mnt/glusterSD/*/[0-9]*/images/
-not -user vdsm -print
A full output of ls -lahRZ, showing user, group, permissions bits, and
selinux label
of the entire tree will be more useful.
>Also, to make sure we don't have selinux issue on the hypervisor, you can
change
>selinux to permissive mode:
> setenforce 0
This is the first thing I did and the systems were still in permissive
when I tried again.I'm 99.99% sure it's not selinux.
>And then try again. If this was selinux issue the permission denied issue
will disappear.
>If this is the case please provide the output of:
> ausearh -m AVC -ts today
>If the issue still exists, we eliminated selinux, and you can enable it
again:
> setenforce 1
[root@ovirt3 ~]# ausearch -m AVC -ts today
<no matches>
[root@ovirt2 ~]# ausearch -m AVC -ts today
<no matches>
[root@ovirt1 ~]# ausearch -m AVC -ts today
<no matches>
So this is not selinux on the hypervisor. I wonder if it can be selinux on
the gluster side?
I have a vague feeling that the issue is related to gluster v6.5 to 6.6
upgrade which I several days before... So if any logs are needed (or debug
enabled), just mention.
If this is the last change, and it worked before, most likely.

Anyone got an idea why is it happening?I checked user/group and selinux permissions - all
OKI even replaced one of the disks and healed , but the result is the same for all my
VMs.
Have you checked the permission for user/group are set correctly
across all the bricks in the cluster?Seem OK:
root@ovirt1 ~]# for i in ovirt{1..3};
do echo $i; ssh $i "find /gluster_bricks/*/*/[0-9]* -not -user vdsm -not -type l
-print" ; echo;echo; doneovirt1
ovirt2
ovirt3
What does ls -la on the images directory from mount of the volume show
you.Attached the output.
Adding Krutika and Rafi as they ran into a similar issue in the past.Most probably the
root's dd is putting the image into the ram ,and then the second dd (via sudo -u vdsm)
gets it from linux cache...

Hello All,
my engine is back online , but I'm still having difficulties to make vdsm powerup the
systems.I think that the events generated today can lead me to the right direction(just an
example , many more are there):
VDSM ovirt3.localdomain command SpmStatusVDS failed: Cannot inquire

directory')
I will try to collect a fresh log and see what is it complaining about this time.
Best Regards,Strahil Nikolov
Hi Sahina,
I have a strange situation:
1. When I try to access the file via 'sudo -u vdsm dd if=disk of=test bs=4M' the
command fails on aprox 60MB.
2. If I run same command as root , remove the file and then run again via vdsm user ->
this time no i/o error reported.
My guess is that I need to check what's going on the bricks
themselve ...

Hi Sahina,
Sadly engine logs have no errors.I've got only an I/O error, but in the debug of the
vdsm I can clearly see that "qemu-img" is giving an "OK".During the
upgrade I got some metadata files pending heal, but I have recovered the conflict manually
and should be OK.Today I have defined one of the VMs manually (virsh define) and then
started it , but the issue is the same.It seems to be storage-related issue,as VMs that
are on specific domain can be started , but most of my VMs are on the fast storage domains
and none of them can be started.
After the gluster snapshot restore , the engine is having issues and I have to separately
investigate that (as I poweroff my HostedEngine before creating the snapshot).
The logs can be find at
: https://drive.google.com/open?id=1VAZFZWWrpimDeVuZT0sWFVXy76scr4NM
Any ideas where to look at , as I can definitely read (using "dd if=disk" or
qemu-img info) the disks of the rhel7 VM ?
The vdsm logs have this:2019-11-17 10:21:23,892+0200 INFO (libvirt/events) [virt.vm]

Was it reset after upgrade?
Are you able to copy this file to a different location and try running a VM with this
image?
Any errors in the mount log of gluster1:_data__fast volume?

So far,
I have rolled back the engine and the 3 hosts - still cannot manipulate the storage.It
seems that gluster itself is working, but vdsm and the oVirt stack cannot access the
storage - cannot create new VM disks, cannot start a VM and I'm on the verge of
redeploy.
Any errors in vdsm logs? engine logs?

I got upgraded to RC3 and now cannot power any VM .
Constantly getting I/O error, but checking at gluster level - I can dd from each disk or
even create a new one.
Removing the HighAvailability doesn't help.
I guess I should restore the engine from the gluster snapshot and rollback via 'yum
history undo last'.
Does anyone else have my issues ?

Hello,
I have a question about bugs, which are flagged as [downstream clone - 4.3.7], but are not
yet released.
I'm talking about this bug:https://bugzilla.redhat.com/show_bug.cgi?id=1749202
I can't see it in 4.3.7 release notes. Will it be included in a further release
candidate? This fix is very important I think and I can't upgrade yet because of this
bug.
Looking at the bug, the fix was done with $ git tag --contains
12bd5cb1fe7c95e29b4065fca968913722fe9eaaovirt-engine-4.3.6.6
ovirt-engine-4.3.6.7
ovirt-engine-4.3.7.0
ovirt-engine-4.3.7.1
So the fix is already included in release oVirt 4.3.6.
Sent a fix to 4.3.6 release notes: https://github.com/oVirt/ovirt-site/pull/2143. @Ryan
Barry can you please review?
