[Ocfs2-users] Any chance using OCFS2 as a distributed file system (without a shared disk)?

Another possible option would be to use DRBD (http://www.drbd.org) along with OCFS2 which would allow you to run DRBD in "dual-primary mode". I know of a few people that are using this setup on 2 node web clusters and it works very well for them. However I don't know if you can run this with more than 2 nodes. 

The user guide for DRBD can be found here http://www.drbd.org/users-guide/
