Is there a different way I should populate > ceph.conf to get everything to work correct? ceph.conf host= entries must match the output of "hostname" (strictly, up to first dot of "hostname -f", which isn't exactly the same as "hostname", but I'm too late to that fight); that's what the sysvinit script assumes, and if it ain't right, it won't start your daemons. It sounds like you want to set set public_network and cluster_network in [global] both to 10.30.0.0/8. -- To unsubscribe from this list: send the line "unsubscribe ceph-devel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
