[lustre-discuss] A project quota question

Hi All,

I am trying to arrange quotas for a University's cluster , on our new ES400 running  DDNs Lustre 2.12.
Somehow, there is a desire to have nested quota : like, Faculty quota then Professors research group quota.

Using "group" quota (as in Unix group) is something that I’d like to avoid if possible, because users come from LDAP with their own group as default (i.e., user:user) . 
The users then are prone to mix up ownership of their files on the system with their PI group (user:pi-group), which creates a few support tickets when a wrong group goes over quota.

Is it possible to have nested project quota on Lustre 2.12? Or, more than one project ID on a directory? 

Faculty1 : project Id 1
 __ PI-group1 : Project id1, project id 2
__ __ User1, user1 : inherit both ids from the Pi-group dir
__ Pi-group 2: Project id 1, project id 3

Etc.

Thanks!
