Description
take osd.0 as an example. it serves nine pgs in total. and serves three pgs as the last replica: saying acting osd sets [12,13,0], [8, 3, 0], [7, 9, 0].
Then ceph osd out 0. it triggered pg recovery.
finally those pgs with last replica in osd.0 will be kept in degraded status with two osds, saying [12,13], [8, 3], [7, 9].
It seems to be a crush bug. crush can't handle recover those pgs after several retries t choose a new osd for the last replica, unless the osd.0 is removed from crush map.

You need to increase the number of retries with only three hosts.
