Race condition loading modules causes mount to fail

Bug Major Resolved Won't Fix WC Triage Wally Wang patch Tue, 19 Jul 2011 20:47:38 +0000 Wed, 3 Oct 2012 17:35:21 +0000 Wed, 3 Oct 2012 17:35:21 +0000 Lustre 2.1.0 0 2 <p>Patch from Oracle bug 24464, attachment 32987 is in:</p> <p><a href="http://review.whamcloud.com/#change,1117" class="external-link" target="_blank" rel="nofollow noopener">http://review.whamcloud.com/#change,1117</a></p> <p>Wally, is this change still needed? If not, please abandon the change and close the bug.</p> <p>Cray has put the modprobe in Cray's own startup script to avoid the problem. Lustre without this patch could still run into the problem. So do you still want to push it or close it for now?</p> <p>It seems we have been years without this patch? Our autotest runs plenty of multi OST servers and I don't think we have seen this issue directly? Perhaps we don't need this patch? </p> <p>The patch as been abandoned. Please reopen if it it still needed. </p> Development Rank 1|hzvi3j: Rank (Obsolete) 6581 Severity
