[Users] Disk reported as a thin allocated disk after live storage migration on iSCSI storage
On RHEV 3.1,after a disk was successfully live migrated from one storage domain to another,I noticed that on the Admin Portal,it was being reported as a Thin allocated disk.It was originally a preallocated disk.Is that expected? Thanks, Marc

yes, since a snapshot was created as part of the migration (until live merge snapshot will be supported to auto-collapse it post the migration)
Thanks, Marc

Itamar, Thanks for confirming that. On the Admin Portal,the 'actual size' of the disk after live disk migration is twice that of the 'actual size' of the disk before migration.Why is that?Would that change once live merge snapshot is supported in the future release?

it should. you can also merge it today, when the VM is down
