    Description

      One OST is deactivated on the MDS via "lctl --device 56 deactivate".

      Now when I try to drain the OST, I can remove (rm) files without an error message, but no space gets freed up on that OST as shown in "lfs df" output.

      I assume it only removed the inode/object on the MDS, but doesn't touch the deactivated OST, leaving all the migrated files behind as orphaned objects on the OST, which is pretty bad.

      If I do the same migration with the OST active, space as shown in "lfs df" does get freed up correctly.
