Ceph » devops

The command:

$ ceph-deploy --cluster ceph0 mon create cephgs-{0,1,2}

runs without error yet it fails to do anything on the monitor hosts. One problem is that the 'service start' command on each host that the above issues does not succeed.

$ /usr/sbin/service ceph start mon.cephgs-0
/etc/init.d/ceph: ceph conf /etc/ceph/ceph.conf not found; system is not configured.
$ echo $?
0

Note that despite failure, the exit status is 0.

Since the cluster is named ceph0, the service-start command should have some pointer to the ceph0.conf file.
