[lustre-discuss] checking and turning on quota enforcement.

[Phill Harvey-Smith]

Hi all,

About a year ago I migrated the departmental lustre servers to new 
hardware, which involved setting up new hardware, installing lustre and 
copying the files over. All of which went OK and we have been using the 
volumes without problems for the last year or so.

However it has just become apparent that the new servers are not 
enforcing quotas, though they are set for all users on two of our 
volumes. This has lead to the situation where one of our volumes is 
almost full, and is negatively affecting performance.

Looking at the documentation for lfs suotaon / quotaoff it suggests that 
they are depreciated since lustre version 2.4.x. We are currently 
running 2.9.0 on Centos 7.

How can I check to see if quota enforcement is turned on, and if not 
turn it on once we have people back under quota again (or adjusted their 
quota).

Cheers.

Phill.
