I turned on the debug option, and this is what I got:

Also I updated my simple script to create the OSD:
ceph osd rm 0
ceph osd crush rm osd.0
ceph osd create
umount /var/lib/ceph/osd/ceph-0
rm -rf /var/lib/ceph/osd/ceph-0
rm -rf /var/lib/ceph/osd/ceph-0
mkdir /var/lib/ceph/osd/ceph-0
ceph auth del osd.0
ceph osd crush add osd.0 1 root=default host=CVM-0-11
mkfs -t xfs -f /dev/hioa
mount /dev/hioa /var/lib/ceph/osd/ceph-0
ceph-osd --id 0 -d --mkkey --mkfs --osd-data /var/lib/ceph/osd/ceph-0
ceph auth add osd.0 osd 'allow *' mon 'allow profile osd' -i
/var/lib/ceph/osd/ceph-0/keyring
/etc/init.d/ceph start osd.0
