Ceph Nautilus 14.2.5, release date: TBA (almost ready)
In this version a possible data corruption bug is fixed that exists in versions 14.2.3 and 14.2.4, OSDs that have separate DB and WAL devices may be subject to checksum erros on the RocksDB.
We will wait until the version get released to upgrade our clusters that use SSDs.
Unecessary HEALTH_ERROR message fixed from backfill miscalculations.
OSDs that have a lot less that 85% usage change their state to backfill_to_full and stop backfilling until a recalculation is done.
ceph-erin suffered from this due to large backfills.
