Description

Cluster is running 94.5 Hammer. Cache tiering backed with replicated pool. This cluster is comprised of six nodes. Three nodes have 12 spinning disk each, and three nodes have 9 SSDs each. This issue began when it was discovered that the cache tier wasn't flushing or evicting objects to the cold tier as a result of a misconfiguration (cluster had full OSD due to improper config).

ceph pg set_full_ratio was set to 0.98 to allow the cluster to continue to service I/O and attempt to flush the cache tier into free space in the cold tier but it was noticed that OSD's were dropping and back_fill_toofull was seen on several PG's due to OSD's in the cache tier being over 85% full.
Options were set to increase backfill_toofull ratios.

OSD's all appeared to be dropping due to this assert (logs from osd.44 and osd.62 are uploaded):

NOTE: a copy of the executable, or `objdump -rdS <executable>` is needed to interpret this.

Currently only 3 out of 27 OSD's in the cache tier are up...

I believe one of these may have been created with --force-nonempty
