I have just tried this with ceph-deploy and it does indeed seem to work. You have to do the following: 1. Pass a "--cluster=<cluster>" argument to ceph-deploy with a new cluster name (your first cluster will have been called 'ceph' by default, call the new one something different) 2. After calling "ceph-deploy new" but *before* calling "mon create-initial", modify your <cluster>.conf file as follows: a. append the custom port number to each address in the "mon_host" setting b. add a [mon.<hostname>] section for each mon, specifying its address and port 3. Remember to pass the "--cluster=<cluster>" argument to all subsequent invocations of ceph-deploy For example, I picked a cluster name "test4" and custom port 5789 for a three-node cluster and my test4.conf looks like this: [global] fsid = 74446e66-89bf-4f56-8807-f6f76333bfac mon_initial_members = gravel1, gravel2, gravel3 mon_host = 192.168.18.1:5789,192.168.18.2:5789,192.168.18.3:5789 auth_cluster_required = cephx auth_service_required = cephx auth_client_required = cephx filestore_xattr_use_omap = true [mon.gravel1] mon addr=192.168.18.1:5789 [mon.gravel2] mon addr=192.168.18.2:5789 [mon.gravel3] mon addr=192.168.18.3:5789 Cheers, John On Mon, Jan 27, 2014 at 9:56 AM, Indra Pramana <indra@xxxxxxxx> wrote: > Hi John, > > Thanks for your reply. > > Can I use ceph-deploy new to deploy the new cluster?
