This procedure worked for us: http://docs.ceph.com/docs/master/releases/nautilus/#v14-2-0-nautilus 13. To enable the new v2 network protocol, issue the following command: ceph mon enable-msgr2 This will instruct all monitors that bind to the old default port 6789 for the legacy v1 protocol to also bind to the new 3300 v2 protocol port. To see if all monitors have been updated,: ceph mon dump and verify that each monitor has both a v2: and v1: address listed. And then make sure all monitors are listed with both protocols in /etc/ceph/ceph.conf, like this: mon_host = [v2:10.1.0.10:3300/0,v1:10.1.0.10:6789/0] [v2:10.1.0.11:3300/0,v1:10.1.0.11:6789/0] [v2:10.1.0.12:3300/0,v1:10.81.0.12:6789/0] -- Yury On Fri, Jun 14, 2019 at 05:10:56PM +0100, Bob Farrell wrote: > Hi.
