I'm not sure exactly what might be related and what might not so I'll just paste it all.

We probably should assert cfs_atomic_read(&amp;conn-&gt;c_refcount) &gt; 1 instead of this.</p> <p>Liang</p> <p>Review is on <a href="http://review.whamcloud.com/#change,1074" class="external-link" target="_blank" rel="nofollow noopener">http://review.whamcloud.com/#change,1074</a></p> <p>Hi Lai,</p> <p>Is that patch all that is needed to fix this issue?</p> <p>Yes, the log shows that at the time of ASSERT, there are clients which try to connect to OSTs, and connection hash may be rehashed at client connection, while connection will be removed from and added to hash again during rehashing, if ptlrpc_connection_put() assert on (!cfs_hlist_unhashed(&amp;conn-&gt;c_hash)), it will fail (during this assert hash lock is not held).</p> <p>You may verify with this patch on your system. </p> <p>Ok Thanks Lai!</p> <p>This has only come up once so far. Would repeatedly mounting and unmounting the OSTs be a good way to stress test this and see if it comes up? Do there also need to be clients trying to simultaneously read/write to the OST?</p> <p>Yes, umount and mount OST repeatedly is necessary (and before umount recovery should have finished and clients issued some IO), and at the moment there should be new clients mounting lustre filesystem, because connection hash will only be rehashed when new connection is added.</p> <p>Patch <a href="http://review.whamcloud.com/1074" class="external-link" target="_blank" rel="nofollow noopener">http://review.whamcloud.com/1074</a> has landed.
