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?
