Container's private area is located on a local drive, goal is to move it to pstorage.
Container's private area can be moved in online mode using
vzmlocal --online <CTID>::<PSTORAGE_MOUNT_POINT>/private/<CTID>
<CTID>should be replaced with a real container ID
<PSTORAGE_MOUNT_POINT>should be replaced by a path to pstorage mount point
NOTE: Container should be in ploop format prior to migration. Placing vzfs-based container on a pstorage might lead to significant pstorage degradation
