cluster master died - what now?

[mangoo]

That's just a hypothetical situation.

Imagine that your Proxmox VE cluster master died and you can't start it any more.

Without a cluster master, one can't start/stop/VNC guests on the other nodes (at least in the web interface).


What is the recommended way to recover from such a situation (i.e., how to promote another node to be a master if the current master is not present)?

You can control every cluster separately

Anyone of you cluster can become master of clusters. To do it you can try
#pveca -m (force local node to become master)

I can't.
VNC, stopping, starting - if I try to do it on other nodes, I get "You do not have write access".
Do I have anything screwed in my config?

u can ssh to the server ( slave node ) try the following
1- /etc/init.d/httpd restart
2- pveca -m to force it to be master
what happend on master node how it died maybe we can help getting it started

delete /etc/pve/cluster.cfg file in Node server. What way you can start/stop VM

 

[dietmar]

The suggested way is to:

1.) promote a new master with "pveca -m"

2.) tell other nodes that there is a new master with "pvesa -s -h IP" on all nodes.
