In general it’s not, but as you only have 3 degraded PGs and appear to have
several more misplaced ones, you are a lot more likely to have reached some
kind of edge condition where the OSD-local scheduling decisions aren’t
working out quite right at the global level. Or it may be that there’s a
CRUSH error and it can’t figure out where to place new replicas of the PGs
Can you provide a full osd and pg dump in addition to all of “ceph -s”?
