I tried it both before and after creating an lvm physical partition.

>Which version of ceph?

12.2.1

gentooserver ~ # ceph-volume lvm zap /dev/sdb

usage: ceph-volume lvm [-h]

ceph-volume lvm: error: unrecognized arguments: zap /dev/sdb

???

ceph-volume lvm zap /dev/sdb

ceph-volume lvm create --bluestore --data /dev/sdb

The doc at http://docs.ceph.com/docs/master/ceph-volume/lvm/prepare/#ceph-volume-lvm-prepare says I can pass a physical device to ceph-volume. But when I try to do that:

gentooserver ~ # ceph-volume lvm create --bluestore --data /dev/sdb

usage: ceph-volume lvm create [-h] [--journal JOURNAL] --data DATA

                              [--journal-size GB] [--bluestore] [--filestore]

                              [--osd-id OSD_ID] [--osd-fsid OSD_FSID]

ceph-volume lvm create: error: Logical volume must be specified as 'volume_group/logical_volume' but got: /dev/sdb

Am I missing something?
