I have set up a 3 node system. Gluster has its own backend network and I have tried entering the FQDN hosts via ssh as follows... gfs1.gluster.private 10.10.45.11 gfs2.gluster.private 10.10.45.12 gfs3.gluster.private 10.10.45.13 I entered at /etc/hosts 127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4 ::1 localhost localhost.localdomain localhost6 localhost6.localdomain6 gfs1.gluster.private 10.10.45.11 gfs2.gluster.private 10.10.45.12 gfs3.gluster.private 10.10.45.13 but on the CLI host gfs1.gluster.private returns [root@ovirt1 etc]# host gfs1.gluster.private Host gfs1.gluster.private not found: 3(NXDOMAIN) [root@ovirt1 etc]# I guess this is the wrong hosts file, resolver.conf lists files first for lookup...
[root@ovirt1 etc]# host gfs1.gluster.private Host gfs1.gluster.private not found: 3(NXDOMAIN) [root@ovirt1 etc]#
I guess this is the wrong hosts file, resolver.conf lists files first for lookup...
what is resolver.conf ? do you mean /etc/nsswitch.conf ? however, "host" is a tool for querying dns. it does not care about /etc/hosts
It looks like you may have those host entries backward. Put the IP first then the hostname i.e. 1.1.1.1 host.example.com On Fri, Nov 15, 2019 at 8:17 AM <rob.downer@orbitalsystems.co.uk> wrote:

Did you setup ssh keys between the hosts? On Fri, Nov 15, 2019 at 9:16 AM <rob.downer@orbitalsystems.co.uk> wrote:

yes see below... still getting FQDN is not added in known_hosts on Additional hosts screen... Are you sure you want to continue connecting (yes/no)? yes /usr/bin/ssh-copy-id: INFO: attempting to log in with the new key(s), to filter out any that are already installed /usr/bin/ssh-copy-id: INFO: 1 key(s) remain to be installed -- if you are prompted now it is to install the new keys root@gfs3.gluster.private's password: Number of key(s) added: 1 Now try logging into the machine, with: "ssh 'gfs3.gluster.private'" and check to make sure that only the key(s) you wanted were added.

OK so I found that even though DNS was set correctly havng put IP address' in additioanl hosts and adding them to /etc/hosts Deployment does not immediately fail... however it does fail...
