6:15 a.m.
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...
6:32 a.m.
[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
6:32 a.m.
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

So using FQDN or ip I get this

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(a)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.
8:54 a.m.
What is the output of "nmcli general hostname" ?

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...
