I remember discussing this ages ago when we made the initial connection asynchronous, but don't recall exactly why we didn't do it. Still sounds like a good idea to me.</p> <p>there was a discussion at LAD. Developers from Fujitsu said that connections are consuming quite amount of memory. Then we recalled that there are other possible cases where less connection can help - like recovery, cluster startup.</p> <p>Oleg Drokin (oleg.drokin@intel.com) merged in patch <a href="https://review.whamcloud.com/16682/" class="external-link" target="_blank" rel="nofollow noopener">https://review.whamcloud.com/16682/</a><br/> Subject: <a href="https://jira.whamcloud.com/browse/LU-7236" title="connections on demand" class="issue-link" data-issue-key="LU-7236"><del>LU-7236</del></a> ptlrpc: idle connections can disconnect<br/> Project: fs/lustre-release<br/> Branch: master<br/> Current Patch Set: <br/> Commit: 5a6ceb664f07812c351786c1043da71ff5027f8c</p> <p>Landed for 2.12</p> Blocker LU-10018 Related LU-11518 LU-12328 LU-9660 LU-11126 LU-11128 LU-11206 LU-5703 LU-9441 LU-9555 LU-11405 Development Rank 1|hzxp53: Rank (Obsolete) 9223372036854775807
