Hi All. I have a ceph cluster that's partially upgraded to Luminous. Last
night a host died and since then the cluster is failing to recover. It
finished backfilling, but was left with thousands of requests degraded,
inactive, or stale. In order to move past the issue, I put the cluster in
noout,noscrub,nodeep-scrub and restarted all services one by one.
Here is the current state of the cluster, any idea how to get past the
stale and stuck pgs? Any help would be very appreciated. Thanks.
