by Sandro Bonazzola
Hi,
following oVirt 4.1.1 GA the oVirt team identified some bugs worth to be
addressed out of the usual release cycle.
For this reason an async release including these fixes is under preparation.
An update to the following packages have been pushed to the pre-release
repository for testing.
- cockpit-ovirt-0.10.7-0.0.16
- imgbased-0.9.20
- ovirt-engine-4.1.1.8
- ovirt-engine-metrics-1.0.2
- ovirt-release41-4.1.1.1
- ovirt-web-ui-0.1.2-4
- vdsm-jsonrpc-java-1.3.10
- vdsm v4.19.10.1
In order to test it, you'll need pre-release repository enabled:
yum install http://resources.ovirt.org/pub/yum-repo/ovirt-release41-pre.rpm
An update to release notes including bugs related to above packages and
updates applied in bugzilla documentation texts has been pushed
tohttps://github.com/oVirt/ovirt-site/pull/888 for review.

rename storage domain
by Gianluca Cecchi
Hello,
I'm in 4.1.1 and imported a storage domain.
In import window there is option to put name, but actually afterwards the
name is the same as the source one...
Is this expected?
Is there any way to change name of storage domain?
thanks,
Gianluca

Moving from fc based to iSCSI based
by Gianluca Cecchi
Hello,
I have to move some VMs from FCP based storage domain to iSCSI based
storage domain.
Can I do it offline or online keeping in mind that:
Host1, Host2 have access only to the FCP SD
Host3, Host4 have access only to the iSCSI SD
They are all managed by the same engine in the same DC but in different
cluster
I suppose it happens through network, correct?
Thanks in advance,
Gianluca

Question about firewall on hypervisor
by Gianluca Cecchi
Suppose I want to disable firewall at already installed hypervisor side (eg
because I want to setup OVN and currently if I remember correctly it needs
to be disabled for that), can I simply disable the related services through
systemctl stop iptables
systemctl disable iptables
systemctl stop firewalld
systemctl disable firewalld
Or is anything else to do at hypervisor and/or engine side?
I don't see anything in web admin gui editing the host, while when I add
the host there is the checkbox "Automatically configure host firewall"....
Thanks,
Gianluca

Question about import domain and templates
by Gianluca Cecchi
Hello,
in environment A I have 2 storage domains ST1 and ST2
I have to detach ST2 and import it into another environment B.
On ST2 I have some VMs whose template disk is currently on ST1...
Does this constitute a problem at destination import?
I see that for disks of templates I can only copy and not move them...
Can I copy the template disk from ST1 to ST2 befor detaching, so that it
will be imported at destination too?
What should I do at destination, then?
Thanks,
Gianluca

info on performance of cloning a snapshot
by Gianluca Cecchi
Hello,
I'm on 4.1.1 environment.
Storage domain is iSCSI (with multipath) and able to write at about 200
MBytes/s when making a test inside a VM (100MB x 2)
While cloning a snapshot it seems the performace is quite lower...
It begins at about 12MB/s (6 x 2) then increases at about 30MB/s (15 x 2)
with maximum of 50MB/s (25 x 2), all balanced across the two iSCSI network
adapters
The related process on hypervisor

Not a big problem, only to know: is there any limiting/tunable factor in
any vdsm/engine parameter?
Or is it related to the command "qemu-img convert" itself or anything else?
Thanks,

general storage exception ... not using lvmetad
by Gianluca Cecchi
Hello,
on my 4.1 environment sometimes I get this kind of message, typically when
I create a snapshot.
Please note that the snapshot is correctly created: I get the event between
the snapshot creation initiated and completed events
VDSM ovmsrv05 command TeardownImageVDS failed: Cannot deactivate Logical
Volume: ('General Storage Exception: ("5 [] [\' WARNING: Not using lvmetad

What is the exact meaning and how can I crosscheck to solve the possible
anomaly...?
What about lvmetad reference inside the message? Is it an option that in
oVirt can be configured or not at all for now?
Thanks,
Gianluca

VM has been paused due to storage I/O problem
by Gianluca Cecchi
Hello,
my test environment is composed by 2 old HP blades BL685c G1 (ovmsrv05 and
ovmsrv06) and they are connected in a SAN with FC-switches to an old IBM
DS4700 storage array.
Apart from being old, they seem all ok from an hw point of view.
I have configured oVirt 4.0.6 and an FCP storage domain.
The hosts are plain CentOS 7.3 servers fully updated.
It is not an hosted engine environment: the manager is a vm outside of the
cluster.
I have configured power mgmt on both and it works good.
I have at the moment only one VM for test and it is doing quite nothing.
Starting point: ovmsrv05 is in maintenance (since about 2 days) and the VM
is running on ovmsrv06.
I update qemu-kvm package on ovmsrv05 and then I restart it from web admin
gui:
Power Mgmt --> Restart
Sequence of events in pane and the problem in subject:

Watching the timestamps, the culprit seems the reboot time of ovmsrv05 that
detects some LUNs in owned state and other ones in unowned
Full messages of both hosts here:

and
https://drive.google.com/file/d/0BwoPbcrMv8mvcjBCYVdFZWdXTms/view?usp=sha...
At this time there are 4 LUNs globally seen by the two hosts but only 1 of
them is currently configured as the only storage domain in oVirt cluster.

I don't know exactly the meaning of owned/unowned in the output above..
Possibly it detects the 0:0:1:3 and 2:0:1:3 paths (those of the active
group) as "owned" and this could have created problems with the active node?
On active node strangely I don't loose all the paths, but the VM has been
paused anyway

I'm not an expert of this storage array in particular, and of the rdac
hardware handler in general.
What I see is that multipath.conf on both nodes:
# VDSM REVISION 1.3
defaults {
polling_interval 5
no_path_retry fail
user_friendly_names no
flush_on_last_del yes
fast_io_fail_tmo 5
dev_loss_tmo 30
max_fds 4096
}
devices {
device {
# These settings overrides built-in devices settings. It does not
apply
# to devices without built-in settings (these use the settings in
the
# "defaults" section), or to devices defined in the "devices"
section.
# Note: This is not available yet on Fedora 21. For more info see
# https://bugzilla.redhat.com/1253799
all_devs yes
no_path_retry fail
}
}

Any hint on how to tune multipath.conf so that a powering on server doesn't
create problems to running VMs?
Thanks in advance,
