Both "flock" and "localflock" appear in /proc/mounts

Bug Major Resolved Fixed Andreas Dilger Andreas Dilger Mon, 14 Oct 2019 21:32:13 +0000 Thu, 12 Dec 2019 23:28:32 +0000 Wed, 23 Oct 2019 02:16:33 +0000 Lustre 2.13.0 Lustre 2.12.3 Lustre 2.13.0 Lustre 2.12.4 0 3 <p>AFAICS, this issue affects the flock mode, not just the display.. It makes it very confusing to know which flock behavior is present on a client node. NOTE: it appears that the "most global" option takes precedence, so in this case "<tt>localflock</tt>" is overridden by the default "<tt>flock</tt>" option. It may be possible to work around this issue temporarily by using both "<tt>noflock,localflock</tt>" mount options to first clear the "<tt>flock</tt>" option before enabling "<tt>localflock</tt>". </p> <p>The fix needs a small change to <tt>ll_options()</tt> to fix the parsing of these options. Right now it looks like any one of the options that is passed at mount will set the corresponding <tt>LL_SBI_&#42;FLOCK</tt> option, but does not clear the other options. Any flock option should clear both of the other option flags, and the last one specified wins. </p> <p>Andreas Dilger (adilger@whamcloud.com) uploaded a new patch: <a href="https://review.whamcloud.com/36452" class="external-link" target="_blank" rel="nofollow noopener">https://review.whamcloud.com/36452</a><br/> Subject: <a href="https://jira.whamcloud.com/browse/LU-12859" title="Both &quot;flock&quot; and &quot;localflock&quot; appear in /proc/mounts" class="issue-link" data-issue-key="LU-12859"><del>LU-12859</del></a> llite: clear flock when using localflock<br/> Project: fs/lustre-release<br/> Branch: master<br/> Current Patch Set: 1<br/> Commit: 2543dd9733580a8dbb553b0f84bd77154a9b91f9</p> <p>Oleg Drokin (green@whamcloud.com) merged in patch <a href="https://review.whamcloud.com/36452/" class="external-link" target="_blank" rel="nofollow noopener">https://review.whamcloud.com/36452/</a><br/> Subject: <a href="https://jira.whamcloud.com/browse/LU-12859" title="Both &quot;flock&quot; and &quot;localflock&quot; appear in /proc/mounts" class="issue-link" data-issue-key="LU-12859"><del>LU-12859</del></a> llite: clear flock when using localflock<br/> Project: fs/lustre-release<br/> Branch: master<br/> Current Patch Set: <br/> Commit: 22ee4a1f64eca526ef34a3fd89dc4e95bb307732</p> <p>Landed for 2.13</p> <p>Minh Diep (mdiep@whamcloud.com) uploaded a new patch: <a href="https://review.whamcloud.com/36934" class="external-link" target="_blank" rel="nofollow noopener">https://review.whamcloud.com/36934</a><br/> Subject: <a href="https://jira.whamcloud.com/browse/LU-12859" title="Both &quot;flock&quot; and &quot;localflock&quot; appear in /proc/mounts" class="issue-link" data-issue-key="LU-12859"><del>LU-12859</del></a> llite: clear flock when using localflock<br/> Project: fs/lustre-release<br/> Branch: b2_12<br/> Current Patch Set: 1<br/> Commit: e5173badfcb6d3448adb0dc46311285253e19e12</p> <p>Oleg Drokin (green@whamcloud.com) merged in patch <a href="https://review.whamcloud.com/36934/" class="external-link" target="_blank" rel="nofollow noopener">https://review.whamcloud.com/36934/</a><br/> Subject: <a href="https://jira.whamcloud.com/browse/LU-12859" title="Both &quot;flock&quot; and &quot;localflock&quot; appear in /proc/mounts" class="issue-link" data-issue-key="LU-12859"><del>LU-12859</del></a> llite: clear flock when using localflock<br/> Project: fs/lustre-release<br/> Branch: b2_12<br/> Current Patch Set: <br/> Commit: bfa43920135dacffb77adedeac213966ea450b2c</p> Duplicate Related Development Rank 1|i00o0v: Rank (Obsolete) 9223372036854775807 Severity
