Hi, I am using: drbd 0.7.10 heartbeat 1.2.3 RedHat EL 4 I am in the midst of setting up a fail-over cluster. The way I am setting it up it's actually a two-way failover cluster. During normal operation node A will host a specific set of services and be the drbd primary for the associated drbd disk, and node B similar for another set. For the OS level partitions I use software raid. As drdbd effectively mirrors the data between two systems I thought I'd save some disk space and just use unmirrored partitions for the drbd devices on both nodes... The problem is of course that when a single disk crashes I will have to force a take-over. As far as I can tell I can use the following option in the 'disk' section to force this: on-io-error panic The panic will force heartbeat on the other node to initiate a take over. But is there another way? E.g. can I somehow make drbd invoke a 'heartbeat stop' on-io-error; and preferably send out an alert message? That way it would be easier for me to log into the crashed node and investigate.. The more I think about it, the more I am starting to get in favor of the 'panic' option to be on the safe side. But I thought I'd ask my question here to see if anyone else has ideas / experience on/with this. Cheers, Tim
