This is a known issue with RocksDB/BlueFS. Discussed multiple time in
this mailing thread...
This should improve starting Nautilus v14.2.12 thanks to the following PRs:
https://github.com/ceph/ceph/pull/33889
https://github.com/ceph/ceph/pull/37091
Please note these PRs don't fix existing spillovers (KV compact or
bluefs data migration using ceph-bluestore-tool to be used to fix them)
but rather avoid them from the appearance.
Thanks,
Igor

Hi,
I have a cluster of 14.2.8.
I created OSDs with dedicated PCIE for wal/db when deployed the cluster.
I set 72G for db and 3G for wal on each OSD.
And now my cluster is in a WARN stats until a long health time.
# ceph health detail
HEALTH_WARN BlueFS spillover detected on 1 OSD(s)
BLUEFS_SPILLOVER BlueFS spillover detected on 1 OSD(s)
osd.63 spilled over 33 MiB metadata from 'db' device (1.5 GiB used of
72 GiB) to slow device
I lookup on google and find https://tracker.ceph.com/issues/38745
I'm not sure if it's the same issue.
How can I deal with this?
THANKS
