<ul></ul><p>Hmm, looking at what happens right now, I think it actually might be adequate for those who read the documentation (so, not me): <a class="external" href="http://ceph.newdream.net/wiki/Standby-replay_modes">http://ceph.newdream.net/wiki/Standby-replay_modes</a>.<br />Right now:<br />The mon_force_standby_active option should only apply to those MDSes configured with "mds_standby_replay" but not with "mds_standby_for[name|rank]". There may be a bug with this under some startup orders, but it should work.<br />Setting mds.a to standby for mds.as, and mds.as to standby for mds.a, AND setting mds.as to "mds_standby_replay" works.<br />Setting mds.a to standby for rank 0, and mds.as to standby for mds.a, AND setting mds.as to "mds_standby_replay" works.</p>
<p>I think this allows all the scenarios one might want, and isn't any harder to configure than the goals listed above?</p> Ceph - Bug #1342: Adjust/fix standby-replay configuration options, handlinghttps://tracker.ceph.com/issues/1342?journal_id=51362011-07-27T16:16:42ZGreg Farnumgfarnum@redhat.com
<ul></ul><p>Okay, after more discussion, we just want it to work properly when you set mds.as to follow mds.a. Right now mds.as will end up in standby (rather than standby-replay) under some/all circumstances.</p> Ceph - Bug #1342: Adjust/fix standby-replay configuration options, handlinghttps://tracker.ceph.com/issues/1342?journal_id=51372011-07-28T09:17:34ZGreg Farnumgfarnum@redhat.com
