I have been using a Proxmox VE 2.0 cluster (2 servers) for months.
Today, I had the "bright idea" to install a GUI on one of the servers. I used
tasksel, and selected the
graphical desktop environment (Gnome).
When I rebooted the server, neither of the servers on the cluster could see each other (shows a red light by the server on the sidebar, no statistics). The VMs on each server are working fine, individually.
pvecm status on the broken server shows
cman_tool: cannot open connection to cman, is it running ?. Running it on the other server outputs a lot of lines (here: http://pastebin.com/HpQfUHTU), but I assume the important bit is
expected votes:2 total votes: 1
pvecm delnode (othernode) on either server outputs:
cluster not ready - no quorum?
Any suggestions as to how I can fix this? Thanks in advance!
