I'm not very good at reading these logs yet, but I notice it had to kill off a bunch of processes to get node1 to unmount. Could this have caused it to be viewed as unstable and hence not failback? I've got the same No, the unmount in the end succeded. ipfail[20237]: 2010/05/19_19:09:07

Hi Nick, I am not an expert in this area but I would expect use of attrd_updater to update any scoring informations that you want to use for constraints. At least this is what pingd uses to update the attributes. So if you have any IPMI monitoring daemon, you could call attrd_updater to modify
