Hello,
Last week I upgraded my production cluster to Pacific. the cluster was
healthy until a few hours ago.
When scrub run 4hrs ago left the cluster in an inconsistent state. Then
issued the command ceph pg repair 7.182 to try to repair the cluster but
ended with active+recovery_unfound+degraded
All OSDs are up and all running bluestore with replication of 3 and minimum
size of 2. I have restarted all OSD but still not helping.
Any recommendations on how to recover the cluster safely?
I have attached result of ceph pg 7.182 query
ceph health detail
