[ovirt-users] Re: 10GB disk created on glusterfs storage has only 4096B in vm

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) 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. Maybe in you case is different. Emy
