Everytime I need to create a cluster in proxmox I suffer a bit PITA. But
now I simply can't do it. I've reinstalled several times and deleted and
recreated the cluster again and again. No luck.

Multicast does not work in this network, so I used unicast. There are
another proxmox cluster in the same network and it's working (it was
very painfull also to install, but once I realized the problem was
unicast and the mtu size, it works very well, except when adding a node,
that always is another pain).

So, I would like to explain how I'm doing this and perhaps I'm pretty
obfuscated to see what is happening.

I've installed two debian 7.1, LVM partitions (not necessary, but I did
it anyway), and installed proxmox. The servers works as expected separately.

The server p01 have the IP: 192.168.200.197
The server p02 have the IP: 192.168.201.191

The two networks are visible each other, and as cluster protocol is udp,
it should work. Am I wrong?

Then on p01, I've created the cluster with "pvecm create testcluster",
it worked
I've copied /etc/pve/cluster.conf to /etc/pve/cluster.conf.new,
increased the version number and add transport="udpu" to the cman
section and added the section <totem netmtu="1400" /> (I tried without
it also). Then I've activated the new configuration throught the GUI.

I've double checked /etc/hosts to assure they resolve the names through
this mechanism.

Then on p02 I tried to add the node with "pvecm add p01" (also tried
with IP and also tried this command from p01, both with hostname and IP
of the p02 node).

root@p02:~# pvecm add p01
root@p01's
password:

copy corosync auth
key
stopping pve-cluster
service
Stopping pve cluster filesystem:
pve-cluster.
backup old
database

Starting pve cluster filesystem :
pve-cluster.

Well, it never works. The node waits for a quorum forever. I can see the
p02 node on the p01 GUI (with a red light), but I have no access.
If I run:
root@p01:~# pvecm status

   2   M     24   2013-09-26 13:04:02  p02

And trying to access from p01 GUI to the local resources of p02, Appears
the message "can't open '/etc/pve/authkey.pub' - No such file or
directory (401)" As the /etc/pve/ mountpoint on p02 is a) read only and
b) not the same than p01 (i.e: on p01 there are more files), and
/etc/pve/authkey.pub is not in p02.

Some help is very appretiated
