Playing with Proxmox but struggling... (unable to copy ssh id)

[hughs]

Hello All

I'm trying to setup a Proxmox cluster on a couple of spare blades at work. I've setup the first one and can connect to it through the web interface and have successfully created some VM's on it. The second blade has Proxmox on it but no VM's. The hardware is the same on both machines and Proxmox was installed from the same iso.

I've created the cluster with

pvecm create TESTC

on Blade1. On Blade2 I run

pvecm add xxx.xxx.xxx.xxx

, but it always comes back with a "Unable to copy ssh ID" error. Google doesn't appear to be able to help me with this one - There are references to the cman service - it's not running on Blade2 and won't start. The only way I've got it to start is by running

pvecm create TESTC

on Blade2 - clearly this is wrong because I've then got two clusters not one.

I've tried re-installing Proxmox and even tried another blade all to no avail. I've also tried

apt-get install cman

but I then get a load of dependency errors.

And yes, my switch will do multicast.

thanks!

Make sure your hosts file is defining your hosts properly and that you can ping the hosts from each-other.

There is definitely connection between the two machines - they can ping each other and I can ssh from one to the other. I've tried the command with the IP, the hostname and the FQDN and always get the "unable to copy ssh ID" error. It's connecting to the other machine when I run the command because it's asking for the password.

Ok, I'm a bit further along with this. So the authorized_keys file in ~/.ssh has a symlink to /etc/pve/priv/authorized_keys, but that file is read only and I cannot change the permissions (Function not implemented).

What now?

/etc/pve/ is read-only if you do not have quorum. I guess that happens because you added a second node, but multicast did not work.

Thanks Dietmar, but I can omping between the machines so I think mutlicast is working.

Maybe you are trying to add the node backwards.
If you perform the add backwards you will get the exact same error you are complaining about.

You have to log into the node you want to add, then run pvecm add <ip of node already in cluster>
