Well, just to close any loopholes, did you also enable quota for the OSTs on the MGS?, i.e.:
lctl conf_param <fsname>.quota.ost=ug You can verify status on the servers with: lctl get_param *.*.quota_slave.info Malcolm. -----Original Message----- From: lustre-discuss [mailto:lustre-discuss-boun...@lists.lustre.org] On Behalf Of Torsten Harenberg Sent: Monday, July 27, 2015 6:27 PM To: lustre-discuss@lists.lustre.org Subject: [lustre-discuss] quota only in- but not decreasing after upgrading to Lustre 2.5.3 Dear all, we run a cluster with 1 MDS server (plus one standby) and 2 OST servers running CentOS 6. Recently we - upgraded a Lustre cluster from 2.1.x to 2.5.3 (clients were on 2.5.3 already) - migrated from NIS to Kerberos (on the MDT, the OSTs had and still have no user information configured into the OS) During the upgrade process, we did a tunefs.lustre --quota /dev/mapper/MGTMDT and for lun in 01 03 05 07 09 0B 0D; do echo "LUN: OST00$lun"; tunefs.lustre --quota /dev/mapper/OST00$lun; done (for all OSTs). Quota seems to be on (and we did a lctl conf_param lustre.quota.mdt=ug on the MDT just to be sure), but the quota (both users and group) is only increasing when saving data but not decreasing after deleting with some "rm" anymore, even if you delete a TB or so. Verified with a couple of users. We use lfs quota -u username /lustre to monitor the quota. A google search did not lead to any hint, so I hope someone on the list has an idea.
