Issues when moving cross quota boundaries within volumes on castor closed

It seems it’s possible to get gluster (the software used to provide the file system service for castor) in a bad state if one try to move something across a boundary for quota (such as a home directory or backed up/nobackup space) if the move would cause quota limits to be violated (i.e. doing a cp/rsync rather than a mv would fail for lack of available space).

Data should not be lost by this, but it will require manual (and time consuming) intervention from the admin side, so we recommend trying to avoid this as far as possible.
