Yes you can.
You need to use:
ceph-bluestore-tool --path /var/lib/ceph/osd/ceph-${OSD}
bluefs-bdev-new-db --dev-target /dev/bluesfs_db/db-osd${OSD}
and
ceph-bluestore-tool --path dev/osd1/ --devs-source dev/osd1/block
--dev-target dev/osd1/block.db bluefs-bdev-migrate
those are not tested and just what i remembered but it should point you
in the richt direction.
greets,
Stefan
