https://jira.whamcloud.com This file is an XML representation of an issue en-us 9.4.14 940014 05-12-2023 https://jira.whamcloud.com/browse/LU-534 Lustre <p>We hit this LBUG frequently on one of our production file systems and now have managed to reproduce reliably on our test file system by exporting the Lustre file system via NFS on one Lustre client and by running a version of racer on a NFS client in the exported Lustre file system. After a few minutes the LBUG will happen on the MDS. We've initially seen this on Lustre 1.6.7.2, then 1.8.3-ddn3.3 and now have been able to reproduce on the test file system after upgrading the MDS to 1.8.6-wc1, leaving the OSSes and clients at 1.8.3-ddn3.3 for now.</p> <blockquote> <p>Jul 25 16:13:50 cs04r-sc-mds02-03 kernel: LustreError: 6854:0:(mds_open.c:1323:mds_open()) ASSERTION(!mds_inode_is_orphan(dchild-&gt;d_inode)) failed: dchild

I'm not sure what has changed on our side though. I'll keep trying and I've downloaded the RPMs with the fix so I'll have them available locally once I can reproduce it.</p> <p>Kind regards,<br/> Frederik</p> <p>ok Frederik then let's close this ticket for now and reopen it if you find that this problem reoccurs in the future and this patch does not address the problem.</p> Bugzilla ID 17764.0 Development Rank 1|hzvi2n: Rank (Obsolete) 6577 Severity
