Hello all, I'm sure this has been discussed before, but I can't seem to find it. I know on older versions of Ceph there was an issue with mclock having no recovery and switching to wpq fixed it. Is this still an issue with 19.2.1? I recently ran into this bug <https://tracker.ceph.com/issues/70390>and various issues with it. In order to help recovery I set norebalance flag, so it would focus solely on undersized PGs. The issue I'm seeing though is sometimes recovering will show nothing despite having X active+undersized+remapped+backfilling. Sometimes restarting a few OSD's will fix the issue and it will start again. I'm tempted to switch to wpq, but that would mean having to slowly restart each OSD, which with undersized would cause IO to stop while some OSD's are restarted. Wanted to get others' thoughts before making the change. Thanks, Curt
