Bug Major Reopened Unresolved Dongyang Li Mahmoud Hanafi Mon, 29 Oct 2018 22:42:11 +0000 Wed, 31 Oct 2018 22:37:28 +0000 Lustre 2.10.5 0 5 <p>This seems likely related to <a href="https://jira.whamcloud.com/browse/LU-11584" title="kernel BUG at ldiskfs.h:1907!" class="issue-link" data-issue-key="LU-11584"><del>LU-11584</del></a></p> <p>It looks like the "<tt>lma</tt>" xattr on the MDT for this inode is corrupted. Unfortunately, this isn't something that LFSCK can fix automatically, since the whole point of those flags is to prevent LFSCK from modifying inodes that have features it doesn't understand.</p> <p>Given that the inode doesn't have a proper Lustre FID either (which is itself stored in the LMA xattr), one option is to just delete this xattr from the MDT filesystem directly, by mounting it as type ldiskfs and then running "<tt>setfattr -x trusted.lma /mnt/XXX/ROOT/path/to/file</tt>". If the file itself has no useful data it could just be deleted entirely.</p> <p>close case. I removed the bad file.</p> <p>ok - thanks</p> <p>I'm going to reopen this issue to track fixing the "<tt>unsupported incompat LMA</tt>" issue, which is different from the "<tt>cannot precreate objects: rc = -116</tt>" issue in <a href="https://jira.whamcloud.com/browse/LU-11584" title="kernel BUG at ldiskfs.h:1907!" class="issue-link" data-issue-key="LU-11584"><del>LU-11584</del></a>, and needs a separate fix.</p> Related LU-11584 Development Rank 1|i005b3: Rank (Obsolete) 9223372036854775807 Severity
