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.

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?
