The key is stored in the ceph cluster config db. It can be retrieved by
KEY=`/usr/bin/ceph --cluster ceph --name client.osd-lockbox.${OSD_FSID} --keyring $OSD_PATH/lockbox.keyring config-key get dm-crypt/osd/$OSD_FSID/luks`

At least ceph thought you the essence of doing first proper testing ;)
Because if you test your use case you either get a positive or negative
result and not a problem.
However I do have to admit that ceph could be more transparent with
publishing testing and performance results. I have already discussed
this with them on such a ceph day. It does not make sense to have to do
everything yourself eg the luks overhead and putting the db/wal on ssd,
rbd performance on hdds etc. Those can quickly show if ceph can be a
candidate or not.
