Bug Description
Ubuntu 16.04.1 LTS
ceph version 10.2.2 (45107e21c568dd
I'm trying to create OSD with command
ceph-deploy osd prepare ceph-node1:dm-2
ceph-deploy osd activate ceph-node1:dm-3
but on activation step it fails with:
** ERROR: error creating empty object store in /var/lib/
As a result I have 1 OSD in but it's down.
I tried to do it manually and it ends with exact same result.
My disk is multipath device /dev/dm-2 which partitions are visible as dm-3 and dm-4 (journal)
I can reproduce it on 3 different machines, with same versions of both ubuntu and ceph, also hardware is the same.
I'm attaching full log from OSD creation.

It looks like problem is with multipath device. I found some bugs in ceph but they are rather old:
