Re: [lustre-discuss] [EXTERNAL] Elegant way to dump quota/usage database?

2021-02-11 Thread Kevin M. Hildebrand
I had the same problem. You can collect this information on a per-OST basis, and do the summation yourself. If you're collecting other metrics already, it's easy to do. We use telegraf and grafana to harvest metrics. On each OSS, under /proc/fs/lustre/osd-*/*-OST*/quota_slave you'll find

We appear to be tripping over the same issues reported recently by Tung-Han Hsieh and Simon Guilbault, namely that cur_grant_bytes is being reduced to a very small value and causing abysmal performance. For example, OSTs 0, 1, and 4 are having poor performance on this client running Lustre

Hi, I just updated a RedHat machine from RHEL8.1 to RHEL8.2, and Lustre from 2.12.4 to 2.12.5. I've built the lustre client from source, using Mellanox OFED 5.0-2.1.8.0. After the update, I can no longer mount my Lustre filesystem- I'm getting the following error: # mount /lustre [ 1482.866631]

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:
