It is very wrong :(
If this was coming from our docs, it needs to be fixed because it will
never work.
If you really want to place both block.db and block.wal on /dev/sdb,
you will need to create one LV for each. ceph-volume will not do this
for you.
And then you can pass those newly created LVs like:
ceph-volume lvm create --osd-id 0 --bluestore --data /dev/sdc
--block.db sdb-vg/block-lv --block.wal sdb-vg/wal-lv
