Error replicating xattr for /tmp/target/d8.lustre-rsync-test/d07/d073/b4: 2

Bug Minor Resolved Fixed John Hammond Andreas Dilger Sun, 7 Oct 2018 14:52:51 +0000 Mon, 29 Oct 2018 16:25:17 +0000 Mon, 29 Oct 2018 16:25:17 +0000 Lustre 2.12.0 Lustre 2.12.0 0 5 <p>The LSOM patch was landed on 2018-07-30, so is likely to be the cause of this problem. It will hopefully go away when the patch for <a href="https://jira.whamcloud.com/browse/LU-11466" title="DoM files should not need LSOM sync for valid attributes on the MDS" class="issue-link" data-issue-key="LU-11466"><del>LU-11466</del></a> lands. </p> <p>However, it isn't clear whether we should return an error from trying to set the <tt>trusted.lsom</tt> xattr or not? Some tools like "cp" and "tar" will try to copy all of the xattrs, and since trusted.som is listed it will generate an error and lists of noise. Similarly, we silently eat any attempt to set trusted.lov directly on an existing file, so that tools don't complain. </p> <p>Separately, it would be good to get a better error message in lustre_rsync, as we discussed. </p> <p>After applied the patch <a href="https://jira.whamcloud.com/browse/LU-11450" title="trusted.som xattr is logged in changelog" class="issue-link" data-issue-key="LU-11450"><del>LU-11450</del></a> trusted.som xattr is logged in changelog, the error messages was gone.</p> <p>John L.
