Hello, I have a storage domain that I have to empty, moving its disks to another storage domain,
Both source and target domains are iSCSI What is the behavior in case of preallocated and thin provisioned disk? Are they preserved with their initial configuration?
yes, they stay within their initial configuration
Thanks. I'll try and report in case of problems
Suppose I have one 500Gb thin provisioned disk Why can I indirectly see that the actual size is 300Gb only in Snapshots tab --> Disks of its VM ?
if you are using live storage migration, ovirt creates a qcow/lvm snapshot of the vm block device. but for whatever reason, it does NOT remove the snapshot after the migration has finished. you have to remove it yourself, otherwise disk usage will grow more and more.
Do you mean the snapshot of the original one? In my case I'm moving from storage domain to storage domain and I would expect nothing remaining at source storage... How can I verify the snapshot still there? Is there any bugzilla entry tracking this? It would be strange if not... Gianluca
