If you want to be able to start your osd's with /etc/init.d/ceph init script, then you better make sure that /etc/ceph/ceph.conf does link the osd's to the actual hostname :) Check out this snippet from my ceph.conf: [osd.0] host = ceph-01 osd crush location = "host=ceph-01-ssd root=ssd" [osd.1] host = ceph-01 [osd.2] host = ceph-01 You see all osd's are linked to the right hostname. But the ssd osd is then explicitly set to go into the right crush location too. Kind regards, Erik.
