[pve-devel] [PATCH container] move_volume: call deactivate volume for the old volid in any case

[Dominik Csapak]

not only when we want to remove it. Otherwise, if the old volume is
mapped (e.g. ceph krbd), we don't unmap it when we're finished.

We have to save if we deactivated successfully before attempting to
remove it. If it was not removed (either because we could not
deactivate, or the remove failed), we add it back as unused.
