osd create error

[jjj jjj]

Hello all,

I have problem with deploy openstack.with juju charm on MASS. Reason is ceph-osd.

My setup is:
MAAS version: 2.3.0
controller 2.3.5
Ubuntu 16.04 xenial

juju charm bundle: Openstack Base Xenial Queens (openstack-charmers-next)

ceph-osd config:
 ceph-osd:
      bluestore: false
      osd-reformat: true
      osd-devices: /dev/vdb /dev/vdc /dev/vdd
      osd-journal: /dev/vde
      osd-journal-size: 10000
      source: cloud:xenial-queens/proposed

Error result after create relation ceph-mon and ceph-osd is:

so problem is Unable to create new logical volume with no extents.

 partition info for /dev/vdb is:

any idea?

thx
