bluestore doesn't have a journal like filestore, but probably you mean
block.db ? The naming conventions are different.
In the case of bluestore, what you are describing doesn't require to
have split LVs for each OSD component. You can simply do this:
ceph-volume lvm create --bluestore --data /dev/sdb
Behind the scenes, ceph-volume will create the vg/lv for /dev/sdb and
get everything working
