What does "ceph osd df" give you? There is a column with "OMAP" and "META". OMAP is ~ 13 B, META 26 GB in our setup. Quite a few files in cephfs (main reason we have large OMAP).
Another question is: hoe to use this ceph-kvstore-tool tool to compact the rocksdb? (can't find a lot of examples)
If you want to do a whole host a the time:
systemctl stop ceph-osd.target
wait a few seconds till all processes are closed.
for osd in `ls /var/lib/ceph/osd/`; do (ceph-kvstore-tool bluestore-kv /var/lib/ceph/osd/$osd compact &);done
This works for us (no seperate WAL/DB). Check the help of the ceph-kvstore-tool if you have to do anything special with separate DB / WAL devices.
