Description

when  setting project Id using lfs project -p <project_id> we started to get errors on the mds and oss in dmesg :"LustreError: 168043:0:(lproc_quota.c:246:lprocfs_quota_seq_show()) babilon-OST0000-osd: failed to get rec: rc = -2

  cat: /proc/fs/lustre/osd-zfs/babilon-MDT0000/quota_slave/acct_project: No such file or directory" . this issue we have also tested the issue with alma 9.4 and lustre 2.16.1 and it seems to be fixed at tag v2.16.52 . the openzfs version we have tested are 2.2.7 and 2.2.8.
