This is computed at libcfs module insert time and logged into the debug log, but are not available if the debug log has wrapped. </p> LU-11698 Add debugfs file to print checksum speed Improvement Minor Resolved Fixed Arshad Hussain Andreas Dilger Sun, 25 Nov 2018 22:09:34 +0000 Wed, 28 Jul 2021 00:19:43 +0000 Thu, 8 Jul 2021 13:02:30 +0000 Lustre 2.15.0 0 2 <p>Arshad Hussain (arshad.hussain@aeoncomputing.com) uploaded a new patch: <a href="https://review.whamcloud.com/43943" class="external-link" target="_blank" rel="nofollow noopener">https://review.whamcloud.com/43943</a><br/> Subject: <a href="https://jira.whamcloud.com/browse/LU-11698" title="Add debugfs file to print checksum speed" class="issue-link" data-issue-key="LU-11698"><del>LU-11698</del></a> libcfs: Add checksum speed in debugfs<br/> Project: fs/lustre-release<br/> Branch: master<br/> Current Patch Set: 1<br/> Commit: ec239b70d53e0e43a4c29f1265fe3d65de339b68</p> <p>Oleg Drokin (green@whamcloud.com) merged in patch <a href="https://review.whamcloud.com/43943/" class="external-link" target="_blank" rel="nofollow noopener">https://review.whamcloud.com/43943/</a><br/> Subject: <a href="https://jira.whamcloud.com/browse/LU-11698" title="Add debugfs file to print checksum speed" class="issue-link" data-issue-key="LU-11698"><del>LU-11698</del></a> libcfs: Add checksum speed under /sys/fs<br/> Project: fs/lustre-release<br/> Branch: master<br/> Current Patch Set: <br/> Commit: d775f9ae37975c853984b67f6d1a21e6ec8a8c3d</p> <p>Landed for 2.15</p> <p>Arshad, one thing I noticed is that there are "{<tt>osc,mdc}.&#42;.checksum_type</tt> files on the client, but there are no corresponding "{<tt>mdt,ofd}.&#42;.checksum_type</tt>" files on the servers that report which checksum types are currently supported. It isn't possible to see this just from the client-side <tt>checksum_type</tt> because those may only list the fastest subset of types reported by the server.</p> <p>Would you be interested to implement this?</p> <p>Andreas, yes. I will take this up. Opened <a href="https://jira.whamcloud.com/browse/LU-14889" title="checksum_type support for server" class="issue-link" data-issue-key="LU-14889"><del>LU-14889</del></a> for this.</p> Development Rank 1|i006tr: Rank (Obsolete) 9223372036854775807
