If it's upgraded from 2.1, that's could be dup of <a href="https://jira.whamcloud.com/browse/LU-3784" title="Quota issue on system upgraded to 2.4.x" class="issue-link" data-issue-key="LU-3784"><del>LU-3784</del></a>, and you need to upgrade your e2fsprogs and trigger quota check on the problematic OSTs. I always suggest you upgrade your e2fsprogs to the latest version (1.42.12.wc1-7)</p> <p>There is no way to do quotacheck online. You need to umount the OST and tirgger quotacheck by "tune2fs -O ^quota $ostdev", then "tune2fs -O quota $ostdev" (disable, then re-enable quota feature on OST device).</p> <p>I think there is a need for a better way to do a force quotacheck without unmounting the OST.</p> <blockquote> <p>I think there is a need for a better way to do a force quotacheck without unmounting the OST.</p></blockquote> <p>Well, the purpose of making quota feature as an primary feature in ext4/ldiskfs is to eliminate the needs for qutoacheck. I don't think we should implement an online quotacheck, instead, we'd fix the bug which can cause inconsistency.</p> <p>please close this issue</p> <p>ok Mahmoud</p> Development Rank 1|hzwzhz: Rank (Obsolete) 16287
