lfsck fails in DNE mode

Bug Minor Resolved Fixed Emoly Liu Maloo dne mn4 Mon, 28 Oct 2013 17:38:27 +0000 Fri, 14 Feb 2014 17:39:44 +0000 Mon, 20 Jan 2014 08:08:59 +0000 Lustre 2.4.1 Lustre 2.5.0 Lustre 2.6.0 Lustre 2.4.2 Lustre 2.6.0 Lustre 2.5.1 0 5 <p>The old lfsck code is not going to be updated to handle DNE filesystems. Instead, generate_db() should be updated so that if there are multiple MDTs then e2fsck should still be run, but it should return an error now that <a href="http://review.whamcloud.com/7532" class="external-link" target="_blank" rel="nofollow noopener">http://review.whamcloud.com/7532</a> has landed. </p> <p>Does that mean when running old lfsck on a DNE filesystem, we only generate mds db for master MDS, and return error when generating ost db?</p> <p>Ideally there would also be an error when generating the mdsdb, but yes your statement is correct. The goal is that the old e2fsck/lfsck tool will not be allowed to run on a DNE filesystem, so that it does not corrupt it or delete all of the files on the non-zero MDTs. </p> <p>patch tracking at: <a href="http://review.whamcloud.com/8206" class="external-link" target="_blank" rel="nofollow noopener">http://review.whamcloud.com/8206</a></p> <p>Lustre Build: <a href="http://build.whamcloud.com/job/lustre-b2_4/67/" class="external-link" target="_blank" rel="nofollow noopener">http://build.whamcloud.com/job/lustre-b2_4/67/</a><br/> MDSCOUNT=4</p> <p>The same failure occurred:<br/> <a href="https://maloo.whamcloud.com/test_sets/3245ab52-66a8-11e3-ab63-52540035b04c" class="external-link" target="_blank" rel="nofollow noopener">https://maloo.whamcloud.com/test_sets/3245ab52-66a8-11e3-ab63-52540035b04c</a></p> <p>Lustre Build: <a href="http://build.whamcloud.com/job/lustre-b2_4/69/" class="external-link" target="_blank" rel="nofollow noopener">http://build.whamcloud.com/job/lustre-b2_4/69/</a> (2.4.2 RC1)<br/> MDSCOUNT=4</p> <p>The same failure occurred:<br/> <a href="https://maloo.whamcloud.com/test_sets/5ce9b330-6874-11e3-a9a3-52540035b04c" class="external-link" target="_blank" rel="nofollow noopener">https://maloo.whamcloud.com/test_sets/5ce9b330-6874-11e3-a9a3-52540035b04c</a></p> <p>Lustre Build: <a href="http://build.whamcloud.com/job/lustre-b2_5/5/" class="external-link" target="_blank" rel="nofollow noopener">http://build.whamcloud.com/job/lustre-b2_5/5/</a><br/> Distro/Arch: RHEL6.4/x86_64<br/> MDSCOUNT=2</p> <p>The same failure occurred:<br/> <a href="https://maloo.whamcloud.com/test_sets/15acdebe-7497-11e3-8b21-52540035b04c" class="external-link" target="_blank" rel="nofollow noopener">https://maloo.whamcloud.com/test_sets/15acdebe-7497-11e3-8b21-52540035b04c</a></p> <p>Patch landed for 2.6</p> <p>Here is the back-ported patch for Lustre b2_5 branch: <a href="http://review.whamcloud.com/9176" class="external-link" target="_blank" rel="nofollow noopener">http://review.whamcloud.com/9176</a></p> Duplicate LU-4255 Development Rank 1|hzw6zr: Rank (Obsolete) 11277 Severity
