Don't know if this has been discussed before, but it seems like with 8.3's dual primary support, it's possible to set up a 3-node, all active drbd cluster.
Each node would be dual primary with each other node. Node A would form drbd0 with node B and drbd1 with node C. Node B would have drbd0 with A and drbd2 with C. And, C would have drbd1 with A and drbd2 with B. Then you can use software raid to create md0 on each node with its respective drbd devices. Noce A: md0 (drbd0, drbd1) Node B: md0 (drbd0, drbd2) Node C: md0 (drbd1, drbd2) Then format md0 on each node with a cluster filesystem like ocfs2 with each node as a member of the cluster. Do the drbd experts here have any thoughts on how this idea would go horribly wrong? Thanks for any input and feedback. -- Jiann-Ming Su "I have to decide between two equally frightening options.
