no ceph vg found on when attempting to create OSD

When trying to create a new OSD using an SSD partition for its DB I get the following error:

# pveceph osd create /dev/sdb --crush-device-class hdd --db_dev /dev/sdc5 --db_dev_size 590
create OSD on /dev/sdb (bluestore)
creating block.db on '/dev/sdc5'
no ceph vg found on '/dev/sdc5'

seems the following were needed

pvcreate /dev/sdc5
vgcreate ceph-$(uuidgen) /dev/sdc5
