We wish to have an option to still enable soft quotas but prevent the soft quota from becoming a hard block if the usage is below the hard quota levels. In other words, the user would still be notified the soft quota has been reached, but they wouldn't ever be blocked from writing unless they hit the hard quota limits.</p> <p>I can envision a couple similar approaches to this: you could have an option that allows an inifinite grace period (e.g. lfs setquota -t -1 ...), or you could have an option that prevents the soft quota from ever becoming a hard quota.</p> Lustre 2.8+ <br/> Quotas enabled LU-12280

Provide option to disable soft quota expiration

Improvement Minor Resolved Fixed Hongchao Zhang Cameron Harr llnl Thu, 9 May 2019 23:43:15 +0000 Thu, 20 Feb 2020 13:08:45 +0000 Thu, 20 Feb 2020 13:06:57 +0000 Lustre 2.14.0 0 6 <p>According to the <tt>lfs setquota</tt> usage message and <tt>lfs-setquota.1</tt> man page (added in commit <tt>v2&#95;10&#95;50&#95;0&#45;114&#45;gd2e3bff</tt>) the maximum quota grace period is <tt>2^48 - 1</tt> seconds. It probably makes sense to just map <tt>-1</tt> to <tt>2^48 - 1</tt> inside <tt>lfs&#95;setquota&#95;times()</tt> to make this easier to use. That is about 9M years, so <em>probably</em> long enough... The <tt>lfs&#95;setquota&#95;times()</tt> code checks in that code use <tt>UINT_MAX</tt> as the maximum value, and internally it is stored in a 64-bit value, so I'm not totally sure where the 2^48 second limit comes from, but in any case this is long enough.</p> <p>Hongchao</p> <p>Interested in your thoughts on this one</p> <p>Peter</p> <p>Any further thought on this?</p> <p>Hongchao Zhang (hongchao@whamcloud.com) uploaded a new patch: <a href="https://review.whamcloud.com/36017" class="external-link" target="_blank" rel="nofollow noopener">https://review.whamcloud.com/36017</a><br/> Subject: <a href="https://jira.whamcloud.com/browse/LU-12280" title="Provide option to disable soft quota expiration" class="issue-link" data-issue-key="LU-12280"><del>LU-12280</del></a> quota: add notfy grace<br/> Project: fs/lustre-release<br/> Branch: master<br/> Current Patch Set: 1<br/> Commit: 8dba9c03ea6bb883f5f88cde3ec003ba4a70960b</p> <p>Oleg Drokin (green@whamcloud.com) merged in patch <a href="https://review.whamcloud.com/36017/" class="external-link" target="_blank" rel="nofollow noopener">https://review.whamcloud.com/36017/</a><br/> Subject: <a href="https://jira.whamcloud.com/browse/LU-12280" title="Provide option to disable soft quota expiration" class="issue-link" data-issue-key="LU-12280"><del>LU-12280</del></a> quota: add notify grace<br/> Project: fs/lustre-release<br/> Branch: master<br/> Current Patch Set: <br/> Commit: 58811dd55434332d20142f49ac73165b3bffb9a6</p> <p>Landed for 2.14</p> Related LU-12692 Development Rank 1|i00g2f: Rank (Obsolete) 9223372036854775807
