Hello,

Not sure IO could be the case. The underlying storage itself is brand new
(nvme) connected with FC and is barely at 10 % capacity with low IOPS and
practically zero latency. There are no IO limitations on the LUN itself. I
would also be able to see any IO problems on the other VMs (none in this
case).

I'm out of ideas on what to do for the time how to stop / complete the
task. Any suggestion welcome.

Shutting down the VM in this state means that It probably wont start back
(snapshots with disks in illegal state). Worst case I plan to restore this
VM from a backup tonight.

Regards,
