We're starting the process of moving project NFS off of a central server and into project-specific fileservers. Before I start that, I want to determine which projects really use NFS.
'Video' popped up as one of a few projects who use very little space on NFS and/or haven't written to NFS for many months.
Is it possible that we can eliminate your use of NFS entirely? IIRC you have moved most (all?) of your file storage to cinder.
