Bug Minor Resolved Fixed Patrick Farrell James Nunez interop Wed, 18 Sep 2019 17:24:24 +0000 Mon, 13 Dec 2021 03:54:24 +0000 Wed, 23 Oct 2019 03:30:35 +0000 Lustre 2.13.0 Lustre 2.13.0 0 4 <p>Hmm.  This appears to come down to the older server advertising the max xattr size differently in a way that means for large xattrs, it's advertising a slightly larger size than it can actually support.</p> <p>This is for ldiskfs, with our old ~1 MiB xattr limit.  It's not an issue for smaller sizes, or so it seems.</p> <p>As discussed with Andreas, I think the proper thing to do is limit max attr size (in the test scripts) used with older servers to the current XATTR_SIZE_MAX (the kernel constant), 64 KiB.  This should avoid the problem where the older server doesn't properly advertise its xattr size limit, but still let us use the maximum xattr size with newer servers.</p> <p>I'll push a patch in a bit.</p> <p>Patrick Farrell (pfarrell@whamcloud.com) uploaded a new patch: <a href="https://review.whamcloud.com/36240" class="external-link" target="_blank" rel="nofollow noopener">https://review.whamcloud.com/36240</a><br/> Subject: <a href="https://jira.whamcloud.com/browse/LU-12784" title="interop: sanity test 102ha fails with “saving trusted.big on /mnt/lustre/f102ha.sanity failed”" class="issue-link" data-issue-key="LU-12784"><del>LU-12784</del></a> tests: Fix xattr size interop<br/> Project: fs/lustre-release<br/> Branch: master<br/> Current Patch Set: 1<br/> Commit: a653af6e8fb542d4a423ac6f5d0ac1062ad11898</p> <p>Oleg Drokin (green@whamcloud.com) merged in patch <a href="https://review.whamcloud.com/36240/" class="external-link" target="_blank" rel="nofollow noopener">https://review.whamcloud.com/36240/</a><br/> Subject: <a href="https://jira.whamcloud.com/browse/LU-12784" title="interop: sanity test 102ha fails with “saving trusted.big on /mnt/lustre/f102ha.sanity failed”" class="issue-link" data-issue-key="LU-12784"><del>LU-12784</del></a> llite: limit max xattr size by kernel value<br/> Project: fs/lustre-release<br/> Branch: master<br/> Current Patch Set: <br/> Commit: 84097792f56c38265b6eb0417a47c557f81f9461</p> <p>Landed for 2.13</p> <p>"Andreas Dilger &lt;adilger@whamcloud.com&gt;" uploaded a new patch: <a href="https://review.whamcloud.com/45264" class="external-link" target="_blank" rel="nofollow noopener">https://review.whamcloud.com/45264</a><br/> Subject: <a href="https://jira.whamcloud.com/browse/LU-12784" title="interop: sanity test 102ha fails with “saving trusted.big on /mnt/lustre/f102ha.sanity failed”" class="issue-link" data-issue-key="LU-12784"><del>LU-12784</del></a> tests: fix large_xattr_enabled() for ZFS<br/> Project: fs/lustre-release<br/> Branch: master<br/> Current Patch Set: 1<br/> Commit: c82dde4a92bda0d095d3b00da219bc0d3ca68b5a</p> <p>"Oleg Drokin &lt;green@whamcloud.com&gt;" merged in patch <a href="https://review.whamcloud.com/45264/" class="external-link" target="_blank" rel="nofollow noopener">https://review.whamcloud.com/45264/</a><br/> Subject: <a href="https://jira.whamcloud.com/browse/LU-12784" title="interop: sanity test 102ha fails with “saving trusted.big on /mnt/lustre/f102ha.sanity failed”" class="issue-link" data-issue-key="LU-12784"><del>LU-12784</del></a> tests: fix large_xattr_enabled() for ZFS<br/> Project: fs/lustre-release<br/> Branch: master<br/> Current Patch Set: <br/> Commit: ea78489e2fc0083f46d8e6c932fcd09ba822939f</p> Development Rank 1|i00myv: Rank (Obsolete) 9223372036854775807 Severity
