An example is:</p> <p>oi.88/0x240019a58:0x6:0x0<br/> update_log_dir/<span class="error">&#91;0x240019a58:0x6:0x0&#93;</span><br/> oi.10/0x20000000a:0x9:0x0/<span class="error">&#91;0x240019a58:0x6:0x0&#93;</span></p> <p>Note that the oi.88, oi.10, and update_log_dir entries all refer to the same underlying object/file.</p> <p>Per Di, there should be fewer links.</p> Red Hat Enterprise Linux Server release 7.3<br/> lustre-2.8.0_5.chaos-1.ch6.x86_64<br/> zfs-0.7.0-0.5llnl.ch6.x86_64 LU-8833

Because putting these update log files under a name directory will help us understanding what these files are when accessing them with ZPL, so we probably want to keep as it is. If you are ok with that, let's close this ticket, and focus on <a href="https://jira.whamcloud.com/browse/LU-8753" title="Recovery already passed deadline with DNE" class="issue-link" data-issue-key="LU-8753"><del>LU-8753</del></a>. Sorry for the confusion. Thanks.</p> <p>Di,</p> <p>Yes, I agree that this helps find the update log files and we should leave it as it is. This ticket can be closed and the patch abandoned.</p> <p>thanks,<br/> Olaf</p> <p>ok Olaf</p> Development Rank 1|hzyvnr: Rank (Obsolete) 9223372036854775807 Severity
