Yeah, this should work as well...

Would this also work if the OSD only has its primary block device and
the separate WAL device? Like running:
ceph-bluestore-tool --path dev/osd0 --devs-source dev/osd0/block.wal \
--dev-target dev/osd0/block --command bluefs-bdev-migrate
Additionally you might probably need to zap wal device with
ceph-volume after the migration to avoid its attachment to OSD on
node restart. Not completely sure about that though...
Since the WAL device is just a LV I'd remove the LV once the OSD is
back up and in.
Thanks,
Michael
