[Lustre-discuss] Quota question

[Wojciech Turek]

Quotas doesn't work very well in Lustre 1.6.4.x
Qunit allocation doesn't work correctly so practically every time you  
change quota you have to reset it first. There are many bugzilla  
tickets about this issue.
Also after some time of using quotas we experienced LBUG's thus we  
decided to turn them off.
Apparently lustre 1.6.5 will introduce lots of changes to quota code  
in order to fix this flows and as well to allow to introduce new  
features.

Wojciech Turek
