Node disconection, Can't create CT

[Markus]

Hello ,

It happened to me that the node i have with proxmox get disconected without any error in syslog. It appears as a server with a red led and i cant create Containers, BUT i can acces those which are already created. So.. everything works fine but i cant manage my services via proxmox panel.



This is the second time it happen to me, the first one was so long ago and i solved it by restarting the machine but this time i CANT do that since i it will ruin my uptime and i have a bucn of customer using VPS.


Is there any solution to connect again my server with proxmox WITHOUT restarting?


Thank you so much !

I found this post :

http://pve.proxmox.com/pipermail/pve-user/2012-October/004796.html



I tried :



/etc/init.d/pve-manager restart
/etc/init.d/pve-cluster restart


And still the same, then :

cman_tool join -c CLUSTER_NAME



And that is what i get:

cman tool not joining, conf fail.




And when i go to the node, at the tab "services" : "CMAN" and "RGM MANAGER" are stopped.


Does it has to do something with my problem?

Thank you

Let me know if this works... if not and you solve it let me know so i can update it.

Hey!!

Thank you! I finally got it to work fine !!

What i did:

- apt-get update and apt-get dist-upgrade


By doing this it restarted everything without rebooting the server and now it is working fine.

Just in case it happend to me again and there is no new updates.. how will be able to solve the problem?

Thank you very much guys
