Problem with OVF and Bad Volume Specification
by Nur Imam Febrianto
Hi,
Recently we are migrating our existing VM from Existing oVirt cluster, to new oVirt cluster (using el9) and Oracle OLVM.
But we have this strange issue, after detaching storage domain, and then attaching the storage domain in new cluster, VM Impor tdoesnt shows up any vm that are located on this storage domain. In Disk Import, it shows a lot of disk with no aliases at all, and after we do trial and error with our disk, several disk are missing at all, no trace and no whereabout. After further investigation, OVF_STORE only contains 2 VM definition, not all the VM, and it guts truncated whenever we try to extract it using TAR. Update OVF doesnt help at all too. Anybody got any idea how to prevent or solve this ? We still have 3 storage domain and afraid the same thing will happened again.
Thanks before.

Help with Storage Domain Configuration in oVirt
by Maria Jonas
Hi everyone,
I am setting up a new storage domain in oVirt and running into a bit of trouble. I’ve followed the setup guide but the storage domain isn’t showing up in the “Storage” section of the admin portal...
Here’s what I’ve done so far::-
-Created the storage domain in the setup wizard.
-Checked network connections and permissions.
-Verified that the storage is correctly formatted and accessible.
Is there something I might have missed, or any common issues with storage domain configurations: ?? Any advice or troubleshooting tips would be greatly appreciated.
Thanks in advance!
Maria

Problem with Glusterfs Distributed-Replicated volume almost full but only less than 50% used by files.
by Olivier
Hi,
I have a weird problem with my couple Glusterfs-oVirt:
I had two data domain for my VMs on oVirt. The main one (data) is a Distributed-Replicate with 2 x 3 = 6 bricks of ~ 1,4 Tb on 3 servers (2 bricks by server).
It was an extend of a previous 1 x 3 = 3 Replicated volume on the same servers. I had one new disk (and one new brick) on each of these 3 servers.
My concern is the reported use of this volume (almost 100%).
a df -h give me :
df -h .
Filesystem Size Used Avail Use% Mounted on
ovirt1.pmmg.priv:/data 3.4T 3.3T 84G 98% /rhev/data-center/mnt/glusterSD/ovirt1.pmmg.priv:_data
but a du of the same partition give me :
du -hs /rhev/data-center/mnt/glusterSD/ovirt1.pmmg.priv:_data
1.4T /rhev/data-center/mnt/glusterSD/ovirt1.pmmg.priv:_data
and there no hidden folder I could miss in this mount point.
The weird point (the second one) is when I delete a VMs and is disks (main disk and snapshot) I doesn't get back some space on these volume.
Does anyone have an idea of these problem ?
Thank's

Re: HostedEngine migration fail
by doboscsongor＠gmail.com
Yes, I have only the gold crown on the host where the hosted engine is running. On the second host, there is no crown; that field is empty.
When I installed it, I deployed the hosted engine on the host where I have the gold crown. After this step, I created the cluster and added the second host. Do I need to perform any additional steps every time I add a new host to the cluster to be able to migrate the hosted engine VM?

Hosted engine deployment fails on Rocky Linux 9
by mpelicci＠cisco.com
Trying to do a fresh install of ovirt 4.5 on a Rocky Linux 9 host. While running the hosted-engine --deploy --4, I input all of the information. Why is it that the hosted engine is trying to reach out to the CentOS8 repos and is there a way for me to pause the deployment to modify the repo files on the vm?
