Reinstalling cluster node

$

Ok so I have 2 nodes, proxmox and proxmox2.
There was a working cluster, but I decided to reinstall proxmox2, so:

1. I migrated all guests from proxmox2 to proxmox

2. I deleted proxmox2 with "pvecm delnode proxmox2" on proxmox but it has not disappeared
Code:

root@proxmox:~# pvecm nodes
Node  Sts  Inc  Joined              Name
  1  M      4  2013-04-25 20:01:15  proxmox
  2  X    20                        proxmox2

root@proxmox:~# pvecm status
Version: 6.2.0
Config Version: 3
Cluster Name: CLUSTER
Cluster Id: 30647
Cluster Member: Yes
Cluster Generation: 24
Membership state: Cluster-Member
Nodes: 1
Expected votes: 1
Total votes: 1
Node votes: 1
Quorum: 2 Activity blocked
Active subsystems: 5
Flags:
Ports Bound: 0
Node name: proxmox
Node ID: 1
Multicast addresses: X.X.X.X
Node addresses: X.X.X.X

3. I reinstalled proxmox2

4. When joining the new proxmox2 to the cluster, it shows the following error
Code:

root@proxmox2:~# pvecm add proxmox
root@proxmox's password:
unable to copy ssh ID

Now the web interface is not working, I cannot save backup jobs anymore on proxmox.

Then I tried to restart the services (pvestatd, pvedaemon, cman, pve-cluster) on proxmox:

Code:

root@proxmox:~# service pve-cluster start
Starting pve cluster filesystem : pve-clusterfuse: failed to access mountpoint /etc/pve: Transport endpoint is not connected
[main] crit: fuse_mount error: Transport endpoint is not connected
[main] notice: exit proxmox configuration filesystem (-1)
 (warning).

Now I can't even log in to proxmox web interface.
/etc/pve seems to have disappeared entirely

This is a production server, so I can't reinstall it, it's running many guests.
How can I restore a working cluster or at least get the containers off of it?
