This has been reported a few times in the past, and it isn't obvious that recovery will not start until the first client connects. </p> <p>It would also be useful to print something similar in the <tt>recovery_status</tt> file in /proc. </p> LU-8649

Print console message in recovery when waiting for first client

Improvement Major Resolved Fixed Emoly Liu Andreas Dilger Thu, 29 Sep 2016 03:10:34 +0000 Mon, 19 Mar 2018 20:57:59 +0000 Tue, 9 Jan 2018 07:37:40 +0000 Lustre 2.11.0 Lustre 2.10.4 0 6 <p>It would also be useful to improve the <tt>recovery_status</tt> file by adding <tt>WAITING_FOR_CLIENTS</tt> when recovery hasn't started yet would make it more clear to the administrator that recovery won't start until the clients connect. The difficulty is that I don't think we can replace <tt>RECOVERING</tt> completely, since userspace scripts may be checking this.</p> <p><a href="https://jira.whamcloud.com/secure/ViewProfile.jspa?name=jgarlough" class="user-hover" rel="jgarlough">jgarlough</a> wrote:</p> <blockquote> <p>Another confusing terminology in recovery_status is INACTIVE.
