Halt nodes in cluster with cable disconnect

[Miguel Angel Guerrero <kortux@xxxxxxxxx>]

Hi i'm trying to setup a centos cluster with two nodes with cman, drbd, gfs2 and i'm using ipmi for fencing. DRBD is set up between the nodes using a dedicated interface. So, when I unplug the drbd network cable, both nodes power off immediatly (i tried using crossover cable and both nodes connected to a switch, but both scenarios fail), and the logs doesn't seem to show something useful. In a previous thread on this list, it is recommended to deactivate ACPID daemon, even at BIOS level, but I'm still having troubles.

If I simulate a physical disconnection with ifdown command in some node, this node reboots with no hassle, but unpluging the cable kills both nodes. I think the first scenario is correct, but the second one is not what I expect.

Thanks for your help the next are my cluster.conf
