I believe this is the reason. I mean number of OSDs in the “up” set should be at least 1 greater than the min_size for the upgrade to proceed. Or once any OSD is stopped, it can drop below min_size, and prevent the pg from becoming active. So just cleanup the misplaced and the upgrade should proceed automatically.
But I’m a little confused. I think if you have only 2 up OSD in a replicate x3 pool, it should in degraded state, and should give you a HEALTH_WARN. 在 2022年2月11日，03:06，Zach Heise (SSCC) <he...@ssc.wisc.edu> 写道： Hi Weiwen, thanks for replying. All of my replicated pools, including the newest ssdpool I made most recently, have a min_size of 2. My other two EC pools have a min_size of 3. Looking at pg dump output again, it does look like the two EC pools have exactly 4 OSDs listed in the "Acting" column, and everything else has 3 OSDs in Acting. So that's as it should be, I believe? I do have some 'misplaced' objects on 8 different PGs (the active+clean+remapped ones listed in my original ceph -s output), that only have 2 "up" OSDs listed, but in the "Acting" columns each have 3 OSDs as they should. Apparently these 231 misplaced objects aren't enough to cause ceph to drop out of HEALTH_OK status.

Have you checked the number of OSDs in the acting set of every PG is at least 1 greater than the min_size of the corresponding pool?

Yet somehow 1 PG is (apparently) holding up all the OSD upgrades and not letting the process finish. Should I stop the upgrade and try it again? (I haven't done that before so was just nervous to try it).
