I run ceph on Red Hat Enterprise Linux Server 6.4 Santiago, and when I
run "service ceph start" i got:
# service ceph start
ERROR:ceph-disk:Failed to activate
ceph-disk: Does not look like a Ceph OSD, or incompatible version:

ceph-disk: Error: One or more partitions failed to activate
Someone told me "service ceph start" still tries to call ceph-disk which
will create a filestore type OSD, and create a journal partition, is it
true?
ls -l /dev/disk/by-parttypeuuid/

There seems to be two hioa1 partitions there, maybe remained from last
time I create the OSD using ceph-deploy osd prepare?
