Is there any way to dump the Lustre quota data in its entirety, rather than having to call 'lfs quota' individually for each user, group, and project?
I'm currently doing this on a regular basis so we can keep graphs of how users and groups behave over time, but it's problematic for two reasons: 1. Getting a comprehensive list of users and groups to iterate over is difficult- sure I can use the passwd/group files, but if a user has been deleted there may still be files owned by a now orphaned userid or groupid which I won't see. We may also have thousands of users in the passwd file that don't have files on a particular Lustre filesystem, and doing lfs quota calls for those users wastes time. 2. Calling lfs quota hundreds of times for each of the users, groups, and projects takes a while. This reduces my ability to collect the data at the frequency I want. Ideally I'd like to be able to collect every minute or so. I have two different Lustre installations, one running 2.8.0 with ldiskfs, the other running 2.10.8 with ZFS.
