Hi, in old days it was not advised to colocate mon deamons with osd daemons on same host, but I guess that is not true any more. Would it work from stability perspective if we deploy new ceph starting with 3 nodes where we deploy "mon + osd + mds + mgr + iscsi-gw"? Performance and traffic balancing is another queastion, but is it safe to run those daemons on same host? regards, Uģis
