Wow, thanks for the links, they've really help to clear this up a bit for me. >From what I understand, out-of-band IPMI is what allows admins/other cluster nodes to do things such as power cycling. In my case, that's all I need. I just what Node 2 to shoot Node 1 in the head if it misbehaves.
I'll look around and see what's available for Ubuntu in terms of IPMI-related packages. The only thing I'm not so sure of is how Node 2 connects to Node 1 IPMI and vice-versa? I currently have 2 NICs in both machines (one for LAN and one crossover for DRBD). Can the STONITH+Pacemaker setup on Node 2 connect to the IPMI of Node 1 through LAN or does it need to be serial? Or does this simply vary from vendor to vendor?
