You can pass /dev/sdb to ceph-disk-prepare and it will create two
partitions, one for the journal (raw partition) and one for the data
volume (defaults to formatting xfs). This is known as a single device
OSD, in contrast with a multi-device OSD where the journal is on a
completely different device (like a partition on a shared journaling
SSD).
