I had a similar problem, after i migrate the disk from a "Storage Domain" to a second "Storage Domain" the disk size was different and i could not start the vm anymore. The Ovirt error was : "Unable to get volume size for domain" Somehow gluster has some errors when i migrate disks and the disk have different size. What i did was to disable performance.stat-prefetch for the gluster volume(I read it has some bugs if is enabled in gluster 7.x)
thanks for reply. In my case it loks like I have not "performance.stat-prefetch" enabled... [root@ovirt-hci01 ~]# gluster volume info vms Volume Name: vms Type: Replicate Volume ID: ba5fd3b8-0704-4462-8257-94b77a1222c4 Status: Started Snapshot Count: 0 Number of Bricks: 1 x 2 = 2 Transport-type: tcp Bricks: Brick1: 10.0.4.13:/gluster_bricks/vms/vms Brick2: 10.0.4.11:/gluster_bricks/vms/vms Options Reconfigured: performance.client-io-threads: off cluster.eager-lock: enable performance.io-cache: off performance.read-ahead: off performance.quick-read: off user.cifs: off network.ping-timeout: 30 network.remote-dio: off performance.strict-o-direct: on performance.low-prio-threads: 32 features.shard: on storage.owner-gid: 36 storage.owner-uid: 36 transport.address-family: inet storage.fips-mode-rchecksum: on nfs.disable: on cluster.self-heal-daemon: enable ...well, If it is not a default setting... so I set it off... [root@ovirt-hci01 ~]# gluster volume set vms performance.stat-prefetch off volume set: success ...and unbeliavable, it works now! Is it bug in glusterfs 7.6-1.el8 (link?) or something else? Should not be this setting default one?
Also try to look at Disk Snapshots, see if you have a snapshot that does not exist. In my case i had this snapshot problem after migration and i had to delete the snapshot from the database and set the main image disk id as default in the vm.
I have no snapshots of this vm. I just created new vm and try to install it from ISO.
Maybe in you case is different.
Well, it was exactly this case, thanks! Cheers, Jiri
