IOR single shared file test fails

Bug Major Resolved Cannot Reproduce Zhenyu Xu Cliff White Tue, 22 Nov 2011 17:36:24 +0000 Mon, 29 May 2017 02:48:09 +0000 Mon, 29 May 2017 02:48:09 +0000 Lustre 2.2.0 Lustre 1.8.7 0 4 <p>Bobi</p> <p>Could you please look into this one?</p> <p>Thanks</p> <p>Peter</p> <p>This may be related/identical to <a href="https://jira.whamcloud.com/browse/LU-873" title="IOR single shared file test fails" class="issue-link" data-issue-key="LU-873"><del>LU-873</del></a>, filed by LLNL.</p> <p>I took a look at the log. It looks like the client hyperion360 was requesting an RW lock with local cookie: 0x389db5cc182f83cd from OST0000. However, the completion RPC was dropped(client never got this RPC) so that the status of this lock on the server is granted, but client kept waiting completion; then this lock on the client will never be revoked because a process is waitinig for it. This is just my guess because the log was truncated.</p> <p>Please also notice that completion AST is not resendable; also there are several bulk transfer error on the console. I don't know if network ran into problem at that time.</p> <p>LLNL's ticket is <a href="https://jira.whamcloud.com/browse/LU-874" title="Client eviction on lock callback timeout " class="issue-link" data-issue-key="LU-874"><del>LU-874</del></a>.</p> <p>Close old ticket.</p> Development Rank 1|hzw0v3: Rank (Obsolete) 10220 Severity
