These 12 nodes in dist-rep config, are they in replica 2 or replica 3?
The latter is what is recommended for VM use-cases. Could you give the
output of `gluster volume info` ?

When client-quorum is not met (due to network disconnects, or gluster
brick processes going down etc), gluster makes the volume read-only.
This is expected behavior and prevents split-brains. It's probably a bit
late, but do you have the gluster fuse mount logs to confirm this
indeed was the issue?

The VM pause you saw could be because of the unmount.I understand that a
fix (https://gerrit.ovirt.org/#/c/40240/) went in for ovirt 3-.6
(vdsm-4.17) to prevent vdsm from unmounting the gluster volume when vdsm
exits/restarts.
Is it possible to run a test setup on 3.6 and see if this is still
happening?

9 years, 2 months
adding gluster domains
by Brett Stevens
Hi. First time on the lists. I've searched for this but no luck so sorry if
this has been covered before.
Im working with the latest 3.6 beta with the following infrastructure.
1 management host (to be used for a number of tasks so chose not to use
self hosted, we are a school and will need to keep an eye on hardware costs)
2 compute nodes
2 gluster nodes
so far built one gluster volume using the gluster cli to give me 2 nodes
and one arbiter node (management host)
so far, every time I create a volume, it shows up strait away on the ovirt
gui. however no matter what I try, I cannot create or import it as a data
domain.
the current error in the ovirt gui is "Error while executing action
AddGlusterFsStorageDomain: Error creating a storage domain's metadata"
logs, continuously rolling the following errors around

Which version of virt-v2v?
The latest version can be found by reading the instructions here:
https://www.redhat.com/archives/libguestfs/2015-April/msg00038.html
https://www.redhat.com/archives/libguestfs/2015-April/msg00039.html
Please don't use the old (0.9) version.

The new version of virt-v2v does not use '.netrc' at all. Instead
there is a '--password-file' option. Best to read the manual page:

noVNC error
by Michael Kleinpaste
So when I used oVirt 3.4.x noVNC worked wonderfully. We're running
3.5.1.1-1.el6 now and when I try to connect to a VMs console via noVNC I
get this error.
[image: Screen Shot 2015-09-21 at 10.09.23 AM.png]
I've downloaded the ca.crt file and installed it but I still get an HTTPS
error when connecting to the oVirt management console. Looking at the SSL
information Chrome says the following:
"The identity of this website has been verified by
ovirtm01.sharperlending.aws.96747. No Certificate Transparency information
was supplied by the server.
The certificate chain for this website contains at least one certificate
that was signed using a deprecated signature algorithm based on SHA-1."
Is this a known issue?
Thanks,

[ovirt 3.5.4] cannot clone vm after updating to 3.5.4
by wodel youchi
Hi all,
We have o hosted-engine deployment with two hypervisors and iscsi for VMS
and NFS4 for the VM engine + ISO + Export.
Yesterday we did an update from ovirt 3.5.3 to 3.5.4 along with OS updates
for the hypervisors and the VM engine.
After that we are unable to clone VMs, the task does not finish.
We have this in vdsmd log

[ANN] [QE] Bugzilla updates for oVirt Product
by Sandro Bonazzola
The oVirt team is pleased to announce that today oVirt moved to its own
classification within our Bugzilla system as previously anticipated [1].
No longer limited as a set of sub-projects, each building block
(sub-project) of oVirt will be a Bugzilla product.
This will allow tracking of package versions and target releases based on
their own versioning schema.
Each maintainer, for example, will have administrative rights on his or her
Bugzilla sub-project and will be able to change flags,
versions, targets, and components.
As part of the improvements of the Bugzilla tracking system, a flag system
has been added to the oVirt product in order to ease its management [2].
The changes will go into affect in stages, please review the wiki for more
details.
We invite you to review the new tracking system and get involved with oVirt
QA [3] to make oVirt better than ever!

Python: Clone snapshot into VM
by gregor
Hi,
I write currently a little backup tool in Python which use the following
workflow:
- create a snapshot -> works
- clone snapshot into VM -> help needed
- delete the snapshot -> works
- export VM to NFS share -> works
- delete cloned VM -> TODO
Is it possible to clone a snapshot into a VM like from the web-interface?
The above workflow is a little bit resource expensive but it will when
it is finished make Online-Full-backups of VM's.
cheers

Hi,
somehow I got lost about the possibility to do a live storage migration.
We are using OVirt 3.5.4 + FC20 Nodes (virt-preview - qemu 2.1.3)
>From the WebUI I have the following possibilites:
1) disk without snapshot: VMs tab -> Disks -> Move: Button is active
but it does not allow to do a migration. No selectable storage domain
although we have 2 NFS systems. Gives warning hints about
"you are doing live migration, bla bla, ..."
2) disk with snapshot: VMs tab -> Disk -> Move: Button greyed out
3) BUT! Disks tab -> Move: Works! No hints about "live migration"
I do not dare to click go ...
While 1/2 might be consistent they do not match to 3. Maybe someone
can give a hint what should work, what not and where me might have
an error.
Thanks.
Markus
