[SOLVED] cluster : Connection refused (595)

[Nicotontige]

Hi every body,
new on this forum, i need some help / informations to debug my problem.

The configuration :
- 3 nodes (the server : srv00, srv01, srv02)
- OpenVPN

I follow a tutorial on the web to install proxmox through OpenVPN.

I don't have any problem to install the cluster and nodes.

On the web interface i see all 3 nodes, but i only can do "things" on the server i am connected to.

Here, some screens to show you my problem.



i expect that it's a multicast problem, but if it is, i can't see any informations about overs nodes, no ?

I try ssmping, to test it, but it doesn't work.
The result :
asmping 224.0.2.1 x.x.x.x
asmping joined (S,G) = (*,224.0.2.234)
pinging x.x.x.y from x.x.x.x
recv failed: Connection refused errno=111

but with tcpdump, it seems working ....

Someone have encountered the same problem ?

Thanks Nico

Always the same problem...
Some more informations.
With firebug, i see that when i'm on nodes, i get a conenction error for "https://srv00:8006/api2/json/nodes/srv02/status" for example.
I try a pvesh on the master to get this file directly on console, and it's working ...

I supposed that connection between nodes is ok, because i have all the informations, but no access....
All the ssh keys are good, i can connected to all nodes without password.

So, i'm lost .... where is the problem ?

Just for information, i've got 3 version of proxmox
- the cluster master : Linux 2.6.32-29-pve
- node srv01 : Linux 2.6.32-19-pve
- node srv02 : Linux 2.6.32-26-pve

thanks for your help ...

After many hours, the problem was very simple...
In fact, i used Fridu for my firewall, and it blocked everything by default.
I just have to accept everything to pass through the VPN, and it's working.

seems you mix Proxmox VE 2.x with 3.x., this is not supported.

you need to run identical versions in all your cluster nodes (but different kernels are possible).

OK, thanks for this information.
I've search for it on wiki, but i see nothing.
And it will explain why i don't access to the last node.

Upgrade must be done so ^^ !

Thanks !
