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
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.
Thanks,
Gianluca
