deprecating export domain?
by Charles Kozler
Hello,
I recently read on this list from a redhat member that export domain is
either being deprecated or looking at being deprecated
To that end, can you share details? Can you share any notes/postings/bz's
that document this? I would imagine something like this would be discussed
in larger audience
This seems like a somewhat significant change to make and I am curious
where this is scheduled? Currently, a lot of my backups rely explicitly on
an export domain for online snapshots, so I'd like to plan accordingly
Thanks!

Hi Leo,
As you do not have a distributed volume , you can easily switch to replica 2 arbiter 1 or replica 3 volumes.
You can use the following for adding the bricks:

Failed to add storage domain
by thunderlight1＠gmail.com
Hi!
I have installed oVirt using the iso ovirt-node-ng-installer-4.3.2-2019031908.el7. I the did run the Host-engine deployment through Cockpit.
I got an error when it tries to create the domain storage. It sucessfully mounted the NFS-share on the host. Bellow is the error I got:

How to connect to a guest with vGPU ?
by Josep Manel Andrés Moscardó
Hi,
I got vGPU through mdev working but I am wondering how I would connect
to the client and make use of the GPU. So far I try to access the
console through SPICE and at some point in the boot process it switches
to GPU and I cannot see anything else.
Thanks.

ovirt-guest-agent for CentOS 8
by Eduardo Mayoral
Hi,
Just like many of you I am testing my first CentOS 8 VMs on top of ovirt.
I am not finding the package ovirt-guest-agent.noarch . Closest I can
find is qemu-guest-agent.x86_64
After installing and starting it, I do see information reported on the
"Guest info" tab.
Can anybody confirm if this is indeed the agent we should be using? Is
there - or will there be - a more specific package for ovirt guests?
Thanks!

Re: Hyperconverged setup questions
by Strahil
Hi Marko,
I guess you can use distributed-replicated volumes and oVirt cluster with host triplets.

Re: Damaged hard disk in volume replica gluster
by Strahil
As you are replacing an old brick, you have to recreate the old LV and mount it on the same location.
Then you can use the gluster's "reset-brick" (i thing ovirt UI has that option too) and all data will be replicated there.
You got also the "replace-brick" option if you decided to change the mount location.
P.S.: with replica volumes your volume should be still working, in case it has stopped - you have to investigate before proceeding.
Best Regards,

Vm suddenly paused with error "vm has paused due to unknown storage error"
by Jasper Siero
Hi all,
Since we upgraded our Ovirt nodes to CentOS 7 a vm (not a specific one but never more then one) will sometimes pause suddenly with the error "VM ... has paused due to unknown storage error". It happens now two times in a month.
The Ovirt node uses san storage for the vm's running on it. When a specific vm is pausing with an error the other vm's keeps running without problems.
The vm runs without problems after unpausing it.
Versions:
CentOS Linux release 7.1.1503
vdsm-4.14.17-0
