Hi guys,
I've had two different Vm's randomly pause this past week and inside ovirt
the error received is something like 'vm ran out of storage and was
paused'. Resuming the vm's didn't work and I had to force them off and then
on which resolved the issue.
Has anyone had this issue before?
I realise this is very vague so if you could please let me know which logs
to send in.
Thank you
Regards.

Do you have the VMs on thin provisioned storage or sparse disks?
Pausing happens when the VM has an IO error or runs out of space on the
storage domain, and it is done intentionally, so that the VM will not
experience a disk corruption. If you have thin provisioned disks, and the
VM writes to it's disks faster than the disks can grow, this is exactly
what you will see

Hi,
this shouldn't happen imho.
If the VM writes faster than the virtual disk can grow I
would expect the hypervisor to slow down the writing
instead of throwing errors?

we extend before run out of space so it should not really happen in real life, not in
reasonable setups.
unlike the out of space scenario where there's little we can do, just pause.
the threshold for growing the space can be change…or simply use preallocated disks if the
performance is so bad and VM demands so high.
Thanks

Good to know there's a threshold.
how and where can it be configured?
And what is the default value?
Thank you for your fast reply! :)

no... we don't because we don't want to create a performance issue.
the vm is writing until it runs out of space. if we can extend the lv we
do (vdsm will run lvextend).
However, the user should never see this error at all even if we are
running on a thin provision disk since this is a low level operation
which takes very little time.
If we can see the vm's pausing than it's either a UI refresh issue,
internal communication issue between the host and storage or an actual bug.
Adding Eduardo and Federico.

Hi Dan,
Sorry for only coming back to you now.
The VM's are thin provisioned. The Server 2003 VM hasn't run out of
disk space there is about 20Gigs free, and the usage barely grows as
the VM only shares printers. The other VM that paused is also on thin
provisioned disks and also has plenty space, this guest is running
Centos 6.3 64bit and only runs basic reporting.
After the 2003 guest was rebooted, the network card showed up as
unplugged in ovirt, and we had to remove it, and re-add it again in
order to correct the issue. The Centos VM did not have the same issue.
I'm concerned that this might happen to a VM that's quite critical,
any thoughts or ideas?
The only recent changes have been updating from Dreyou 3.2 to the
official Centos repo and updating to 3.3.1-2. Prior to updating I
haven't had this issue.
Any assistance is greatly appreciated.
Thank you.
Regards.
Neil Wilson.

Hi Dan,
Sorry, attached is engine.log I've taken out the two sections where
each of the VM's were paused.
Does the error "VM babbage has paused due to no Storage space error"
mean the main storage domain has run out of storage, or that the VM
has run out?
Both VM's appear to have been running on node01 when they were paused.
My vdsm versions are all...
vdsm-cli-4.13.0-11.el6.noarch
vdsm-python-cpopen-4.13.0-11.el6.x86_64
vdsm-xmlrpc-4.13.0-11.el6.noarch
vdsm-4.13.0-11.el6.x86_64
vdsm-python-4.13.0-11.el6.x86_64
I currently have a 61% over allocation ratio on my primary storage
domain, with 1948GB available.
Thank you.

the storage space is configured in percentages and not physical size.
so if 20G is less than 10% (default config) of your storage it will
pause the vms regardless of how much GB you still have.
this is configurable though so you can change it to less than 10% if you
like.
to answer the second question, vm's will not pause on ENOSpace error if
they run out of space internally but only if the external storage cannot
be consumed. so only if you run out of space in the storage and and not
if vm runs out of space in its on fs.

Thanks for the replies guys,
Looking at my two VM's that have paused so far through the oVirt GUI
the following sizes show under Disks.
VM Reports:
Virtual Size 35GB, Actual Size 41GB
Looking on the Centos OS side, Disk size is 33G and used is 12G with
19G available (40%) usage.
VM Babbage:
Virtual Size is 40GB, Actual Size 53GB
On the Server 2003 OS side, Disk size is 39.9Gb and used is 16.3G, so
under 50% usage.
Do you see any issues with the above stats?
Then my main Datacenter storage is as follows...
Size: 6887 GB
Available: 1948 GB
Used: 4939 GB
Allocated: 1196 GB
Over Allocation: 61%
Could there be a problem here? I can allocate additional LUNS if you
feel the space isn't correctly allocated.
Apologies for going on about this, but I'm really concerned that
something isn't right and I might have a serious problem if an
important machine locks up.
Thank you and much appreciated.
Regards.
Neil Wilson.

Hi Neil,
Can you please attach the vdsm logs?
also, as for the vm's, do they have any snapshots?
from your suggestion to allocate more luns, are you using iscsi or FC?
Thanks,
Dafna

Hi Dafna,
Thanks.
The vdsm logs are quite large, so I've only attached the logs for the
pause of the VM called Babbage on the 19th of Jan.
As for snapshots, Babbage has one from June 2013 and Reports has two
from June and Oct 2013.
I'm using FC storage, with 11 VM's and 3 nodes/hosts, 9 of the 11 VM's
have thin provisioned disks.
Please shout if you'd like any further info or logs.
Thank you.
Regards.
Neil Wilson.

Can you please attach the vdsm logs?
also, as for the vm's, do they have any snapshots?
from your suggestion to allocate more luns, are you using iscsi or FC?

Thanks Neil,
but looking at the logs you sent the ERROR on the vm's have started long
before.
Can you please to grep this thread from all the logs? Thread-286029:
(it's for vm 2736197b-6dc3-4155-9a29-9306ca64881d)
lets try to see when the ERROR started for this thread.
Thanks,
Dafna

Hi guys,
Sorry for the very late reply, I've been out of the office doing installations.
Unfortunately due to the time delay, my oldest logs are only as far
back as the attached.
I've only grep'd for Thread-286029 in the vdsm log. The engine.log I'm
not sure what info is required, so the full log is attached.
Please shout if you need any info or further details.
Thank you very much.
Regards.
Neil Wilson.

OK.
You have several issues in the setup... so it's a bit tricky...
you had a problem with your storage on the 14th of Jan and one of the
hosts rebooted (if you have the vdsm log from that day than I can see
what happened on vdsm side)
in engine, I could see a problem with the export domain and this should
not have cause a reboot. Can you tell me if you had a problem with the
data domain as well or was it just the export domain? were you having
any vm's exported/imported at that time?
In any case - this is a bug.
As for the vm's - if the vm's are no longer in migrating state than
please restart ovirt-engine service (looks like a cache issue)
2014-01-14 09:38:08,590 INFO
[org.ovirt.engine.core.vdsbroker.VdsUpdateRunTimeInfo]
(DefaultQuartzScheduler_Worker-34) RefreshVmList vm id
2736197b-6dc3-4155-9a29-9306ca64881d status = Down on vds
node03.blabla.com ignoring it in the re
fresh until migration is done
if they are in migrating state - there should have been a timeout a long
time ago.
can you please run 'vdsClient -s 0 list table' and 'virsh -r list' on
both all hosts?
Last thing is that your ISO domain seems to be having issues as well.
This should not effect the host status but if any of the vm's were
booted from an iso or have an iso attached in the boot sequence this
will explain the migration issue.
Thanks,
Dafna

Hi guys,
Sorry for the very late reply, I've been out of the office doing installations.
Unfortunately due to the time delay, my oldest logs are only as far
back as the attached.
I've only grep'd for Thread-286029 in the vdsm log. The engine.log I'm
not sure what info is required, so the full log is attached.
Please shout if you need any info or further details.
Thank you very much.

Hi Dafna,
Thanks for coming back to me. I'll try answer your queries one by one.
On Tue, Jan 28, 2014 at 1:38 PM, Dafna Ron <dron(a)redhat.com> wrote:

in engine, I could see a problem with the export domain and this should not
have cause a reboot.
1.) I don't unfortunately have logs going back that far. Looking at
all 3 hosts uptime, the one with the least uptime is 21 days, the
others are all over 40 days, so there definitely wasn't a host that
rebooted on the 14th of Jan, would a network issue or Firewall issue
also cause the error you've seen to look as if a host rebooted? There
was a bonding mode change on the 14th of January, so perhaps this
caused the issue?
Can you tell me if you had a problem with the data
domain as well or was it just the export domain? were you having any vm's
exported/imported at that time?
In any case - this is a bug.
2.) I think this was the same day that the bonding mode was changed on
the host while the host was live (by mistake), and had SPM running on
it. I haven't done any importing or exporting for a few years on this
oVirt setup.
As for the vm's - if the vm's are no longer in migrating
state than please
restart ovirt-engine service (looks like a cache issue)
3.) Restarted ovirt-engine, logging now appears to be normal without any errors.
if they are in migrating state - there should have been a timeout a
long
time ago.
can you please run 'vdsClient -s 0 list table' and 'virsh -r list' on
both
all hosts?
4.) Ran on all hosts...

Last thing is that your ISO domain seems to be having issues as
well.
This should not effect the host status but if any of the vm's were booted
from an iso or have an iso attached in the boot sequence this will explain
the migration issue.
There was an ISO domain issue a while back, but this was corrected
about 2 weeks ago after iptables re-enabled itself on boot after
running updates, I've checked now and the ISO domain appears to be
fine and I can see all the images stored within.
I've stumbled across what appears to be another error and all three
hosts are showing this over and over in /var/log/messages, and I'm not
sure if it's related? ...

yes - engine lost communication with vdsm and it has no way of knowing
if the host is down or if there was a network issue so a network issue
would cause the same errors that I see in the logs.
The error you put on the iso is the reason the vm's have failed
migration - if a vm is run with a cd and the cd is gone than the vm will
not be able to be migrated.
after the engine restart, do you still see a problem with the size or
did the report of size changed?

1.) I don't unfortunately have logs going back that far. Looking at
all 3 hosts uptime, the one with the least uptime is 21 days, the
others are all over 40 days, so there definitely wasn't a host that
rebooted on the 14th of Jan, would a network issue or Firewall issue
also cause the error you've seen to look as if a host rebooted? There
was a bonding mode change on the 14th of January, so perhaps this
caused the issue?

2.) I think this was the same day that the bonding mode was changed on
the host while the host was live (by mistake), and had SPM running on
it. I haven't done any importing or exporting for a few years on this
oVirt setup.

There was an ISO domain issue a while back, but this was corrected
about 2 weeks ago after iptables re-enabled itself on boot after
running updates, I've checked now and the ISO domain appears to be
fine and I can see all the images stored within.
I've stumbled across what appears to be another error and all three
hosts are showing this over and over in /var/log/messages, and I'm not
sure if it's related? ...

Hi Dafna,
Thanks for clarifying that, I found the migration issue and this was
resolved once I sorted out the ISO domain problem.
I'm sorry I don't understand your last question?
"> after the engine restart, do you still see a problem with the size
or did the report of size changed?"
The migration issue was resolved, it's now just trying to track down
why the two VM's paused on their own, one on the 8th of Jan(I think)
and one on the 19th of Jan.
Thank you.
Regards.
Neil Wilson.

Hi Dafna,
Thanks for clarifying that, I found the migration issue and this was
resolved once I sorted out the ISO domain problem.
I'm sorry I don't understand your last question?
"> after the engine restart, do you still see a problem with the size
or did the report of size changed?"
The migration issue was resolved, it's now just trying to track down
why the two VM's paused on their own, one on the 8th of Jan(I think)
and one on the 19th of Jan.
Thank you.
Regards.
Neil Wilson.

The reason I asked about the size if because this was the original issue
no? vm's pausing on lack of space?
You're having a problem with your data domains.
Can you check the rout from the hosts to the storage? I think that you
have some disconnection to the storage from the hosts
since it's random and not from all the vm's I would suggest that its a
routing problem?
Thanks,
Dafna

The reason I asked about the size if because this was the original

Apologies, I just wanted to make sure it was still about this pausing
and not the original migration issue that I think you were also
helping me with a few weeks back.
You're having a problem with your data domains.
Can you check the rout from the hosts to the storage? I think that you have
some disconnection to the storage from the hosts
since it's random and not from all the vm's I would suggest that its a
routing problem?
Thanks,
Dafna
The connections to the main data domain is 8Gb Fibre Channel directly
from each of the hosts to the FC SAN, so if it is a connection issue
then I can't understand how anything would be working. Or am I barking
up the wrong tree completely? There were some ethernet network
bridging changes on each of the hosts in early January, but this would
only affect the NFS mounted ISO domain, or could this be the cause of
the problems?
Is this disconnection causing the huge log files that I sent previously?
Thank you.
Regards.
Neil Wilson.

Apologies, I just wanted to make sure it was still about this pausing
and not the original migration issue that I think you were also
helping me with a few weeks back.

The connections to the main data domain is 8Gb Fibre Channel directly
from each of the hosts to the FC SAN, so if it is a connection issue
then I can't understand how anything would be working. Or am I barking
up the wrong tree completely? There were some ethernet network
bridging changes on each of the hosts in early January, but this would
only affect the NFS mounted ISO domain, or could this be the cause of
the problems?
Is this disconnection causing the huge log files that I sent previously?
Thank you.
Regards.
Neil Wilson.

mmm... I think that there is a bug with the iso domain.... and I am not
sure if it was already opened.
can you help me to debug this and see if its related? :)
I think that you have some intermittent network issues to the iso domain
and every time it happens, the vms that have booted with a cd (even if
you detached it) would pause.
I have a second suspicion... is it possible that the vms that pause had
a cd and you ejected it at some point? perhaps after or during the
network issues you had on the 14th?
can you run dumpxml from libvirt? let me know if you need help with this
command.
Thanks,
Dafna

Apologies, I just wanted to make sure it was still about this pausing
and not the original migration issue that I think you were also
helping me with a few weeks back.

The connections to the main data domain is 8Gb Fibre Channel directly
from each of the hosts to the FC SAN, so if it is a connection issue
then I can't understand how anything would be working. Or am I barking
up the wrong tree completely? There were some ethernet network
bridging changes on each of the hosts in early January, but this would
only affect the NFS mounted ISO domain, or could this be the cause of
the problems?
Is this disconnection causing the huge log files that I sent previously?
Thank you.
Regards.
Neil Wilson.

Hi Dafna,
My sincere apologies for not coming back to you sooner on this. I've
finally had a chance to start investigating, but in between my last
discussion and now, updates have been done on both the hosts and the
engine, so perhaps something there has fixed it, as I haven't had a
pause happen in quite a long time.
When trying to gather the info you requested above I think I've found
what is causing all the excessive logging...that I sent through
previously...
I have a VM called Proxy, which a few years back ran out of disk
space, and wouldn't boot, as it required an fsck, but we'd get an
unknown storage error when doing an fsck on the image, so we had to
attach a new LUN and dd out the entire image, then run an fsck, and
then re-import the image, which got the VM operational again. A while
back we tried to remove the old disk image, and received a storage
error, and looking at this now I see that it appears the old image
never successfully removed. If I look at the VM under Disks I can see
the old disk still attached in place, but there is an hourglass
instead of a green arrow showing. Also right clicking on the Disk the
only option you can choose is Add, so something seems to still have
this locked.
In the logs I have the same error showing over and over...

Any ideas on how to get rid of the "corrupt" disk finally?
Thanks.

mmm... I think that there is a bug with the iso domain.... and I am

if it was already opened.
can you help me to debug this and see if its related? :)
I think that you have some intermittent network issues to the iso domain and
every time it happens, the vms that have booted with a cd (even if you
detached it) would pause.
I have a second suspicion... is it possible that the vms that pause had a cd
and you ejected it at some point? perhaps after or during the network issues
you had on the 14th?
can you run dumpxml from libvirt? let me know if you need help with this
command.
Thanks,

Subject: Re: [Users] Vm's being paused
Hi Dafna,
My sincere apologies for not coming back to you sooner on this. I've
finally had a chance to start investigating, but in between my last
discussion and now, updates have been done on both the hosts and the
engine, so perhaps something there has fixed it, as I haven't had a
pause happen in quite a long time.
When trying to gather the info you requested above I think I've found
what is causing all the excessive logging...that I sent through
previously...
I have a VM called Proxy, which a few years back ran out of disk
space, and wouldn't boot, as it required an fsck, but we'd get an
unknown storage error when doing an fsck on the image, so we had to
attach a new LUN and dd out the entire image, then run an fsck, and
then re-import the image, which got the VM operational again. A while
back we tried to remove the old disk image, and received a storage
error, and looking at this now I see that it appears the old image
never successfully removed. If I look at the VM under Disks I can see
the old disk still attached in place, but there is an hourglass
instead of a green arrow showing. Also right clicking on the Disk the
only option you can choose is Add, so something seems to still have
this locked.
In the logs I have the same error showing over and over...

Any ideas on how to get rid of the "corrupt" disk finally?
This may happen when you migrate a vm from machines running different versions of vdsm.
Vdsm changed the path to the disk lately, so when you migrate a vm, some disk are not
found where vdsm think they should be. This leads to missing format attribute and
libvirt errors when trying to check the status of such disks.
This issue is fixed in upstream:
http://gerrit.ovirt.org/24202
And in ovirt-3.4:
http://gerrit.ovirt.org/24324
I think the best way to avoid this issue, is to have the same vdsm version on all
hosts in the same cluster.

yes - engine lost communication with vdsm and it has no way of
knowing if the host is down or if there was a network issue so a network issue would cause
the same errors that I see in the logs.
The error you put on the iso is the reason the vm's have failed migration - if a vm
is run with a cd and the cd is gone than the vm will not be able to be migrated.
which, as I learned last week, is not entirely correct. Pure libvirt VM seems to work
fine…so it must be somewhere something in oVirt:(
looking into it
but just for future reference we want it to work:)
after the engine restart, do you still see a problem with the size or did the report of
size changed?
