That was the id of the storage domain created on the LUN with problems at storage array level.

It only contained one disk of a VM. I was able to previously move other 2 disks I had on it to another storage domain

The disk was a data disk of a VM; its system disk was on another storage domain without problems

The order of my operations yesterday was:

- try move disk to another storge domain-> failure in auto snapshot

- try snapshot of VM selecting both disks --> failure

- try snapshot of VM selecting only the system disk (the good one) --> ok and also snapshot deletion ok

- try snapshot of VM selecting only the data disk --> failure

- hot add disk (in a good storage domain) to the VM --> OK

- try pvmove at VM OS level from problematic disk to new disk --> failure: VM paused at 47% of pvmove and not able to continue

- power off VM --> OK

- remove disk from VM and delete --> OK

Only at this point, with storage domain empty, I started to work on storage domain itself, putting it to maintenance and removing it without problems; and then the related LUN removal at host level with the notes described in other thread.

 

No, the storage domain has been removed
