Cluster add node when prompted:unable to copy ssh ID。

Code: 
root@prox-0-160:~# pvecm add 192.168.0.161
The authenticity of host '192.168.0.161 (192.168.0.161)' can't be established.
RSA key fingerprint is a9:12:08:7e:01:9c:40:48:f3:9a:20:22:3e:49:0b:a7.
Are you sure you want to continue connecting (yes/no)? yes
root@192.168.0.161's password: 
unable to copy ssh ID
I'm sorry, I made a mistake, it should be 192.168.0.161

You need to make sure that your cluster is 'quorate' - Else the filesystem is switched to read-only mode.

Wnat is the output of

# cat /etc/hostname

and

# cat /etc/pve/cluster.conf

on that node

OK, so tat was the node where the add command failed (so it is clearly not part of the cluster)?

Please fix quorum on you cluster first, the run the add command with the force flag:

# pvecm add 192.168.0.160 --force

Hi,

I had the same error. In my case there was a ssh problem. I set sshd on both nodes to allow only logins with keys so when running the command on node2
pvecm add node1

was problematic because node2 could not ssh to node1 (no keys). So, just make sure first that you are able to ssh as root from and to all nodes.
