2 node cluster - restoring 1 node

[SamTzu]

I just noticed that I forgot to backup /root/ folder on node1 which was re-installed and restored (except the /root folder.)
Is there any way to get the cluster working again if I don't have the proper keys for SSH?

Any one?

just join the cluster again. I guess you need to use the --force argument.

# pvecm add <hostname_of_existing_node> --force

I tried that but it did not work.

root@hp1:~# pvecm add 10.10.10.10 --force
cluster not ready - no quorum?
unable to add node: command failed (ssh 10.10.10.10 -o BatchMode=yes pvecm addnode hp1 --force 1)

I tried that but it did not work.

as the pvecm output said, you need to have cluster quorum first
since you have a 2 node cluster, the only way is to gain quorum issuing
#pvecm e 1
(see http://pve.proxmox.com/wiki/Manual:_pvecm)

then try "add --force" again

Looks like I also missed this folder in backups... /var/lib/pve-cluster/.
After copying it from the other node and starting cman service I was able to set quorum with pvecm e 1 and force the first node back in. Thx all. It works now
