Hi!
I recently played around with PDM, and although I managed to migrate between two hosts a while ago, I tried again today and got the same error again ang again (PDM log):
As the 2 hosts were not on the exact same version, I've upgraded them, as well as PDM to their latest version, but no success either (without rebooting them though...):
Source and destination storage are almost identical (lvmthin):
I managed to find a working command to migrate the storage using a third host for reference (so the
Is that a known issue? Or am I missing something?
Thanks!
