[pve-devel] [PATCH container 2/2] apply_pending_mountpoint: deactivate volumes if not running

[Aaron Lauterer <a.lauterer@proxmox.com>]

Container volumes need to be activated to be formatted. Not deactivating
them afterwards, if the container is not currently running, can lead to
problems.
For example RBD images will get mapped by krbd but not unmapped
afterwards. Reassigning an MP to another CT right after would then lead
to a mapping that needs to be unmapped manually with `rbd unmap` or by
rebooting the node.
