"lfs_migrate" improvements

Improvement Minor Resolved Fixed Steve Guminski Andreas Dilger easy Thu, 18 Dec 2014 22:43:14 +0000 Mon, 5 Nov 2018 23:13:17 +0000 Mon, 6 Nov 2017 17:41:30 +0000 Lustre 2.11.0 Lustre 2.10.4 1 8 <p>I've attached a version of lfs_migrate that deals pretty well with hard links if you specify -l on the command line. it has one bug I decided not to fix: if there are two slashes in a path passed in it does not work well since the paths back from fid2path do not have these in them.</p> <p> Andreas Dilger (andreas.dilger@intel.com) uploaded a new patch: <a href="https://review.whamcloud.com/25851" class="external-link" target="_blank" rel="nofollow noopener">https://review.whamcloud.com/25851</a><br/> Subject: <a href="https://jira.whamcloud.com/browse/LU-6051" title="&quot;lfs_migrate&quot; improvements" class="issue-link" data-issue-key="LU-6051"><del>LU-6051</del></a> utils: allow lfs_migrate to handle hard links<br/> Project: fs/lustre-release<br/> Branch: master<br/> Current Patch Set: 1<br/> Commit: a8083fd4cdcc723b376d4b46370cf019469710ae</p> <p>Hi Evan, great to hear from you again. I pushed your patch to Gerrit for review. </p> <p>In the future it would be great if you submitted the patch directly to Gerrit instead of attaching the whole file to the Jira ticket. Please see the <a href="https://wiki.hpdd.intel.com/display/PUB/Submitting+Changes" class="external-link" target="_blank" rel="nofollow noopener">https://wiki.hpdd.intel.com/display/PUB/Submitting+Changes</a> and <a href="https://wiki.hpdd.intel.com/display/PUB/Using+Gerrit" class="external-link" target="_blank" rel="nofollow noopener">https://wiki.hpdd.intel.com/display/PUB/Using+Gerrit</a> wiki pages for details. Also, if you have a Gerrit account you can be added to the patch for review comments. </p> <p>I made a few cleanups to the patch beore submitting it to gerrit. The one item that still needs to be done is to add a regression test to sanity.sh to test for hard link migration, along with the other lfs_migrate tests. Please see lustre/tests/sanity.sh. . </p> <p>Andreas Dilger (andreas.dilger@intel.com) uploaded a new patch: <a href="https://review.whamcloud.com/25878" class="external-link" target="_blank" rel="nofollow noopener">https://review.whamcloud.com/25878</a><br/> Subject: <a href="https://jira.whamcloud.com/browse/LU-6051" title="&quot;lfs_migrate&quot;
