You don't have to have a mirrored LVM to do what youre trying to do. You just need a common mountable share - typically a SAN or NAS. It shouldn't be too hard to configure (and I've already done it). You don't even *have* to have cluster suite - if you have a load balancer. My brain isn't fast enough today to figure out how to share a load without a load balanced VIP or a DNS round robin (which should be easy to do as well).

Hello all, I have spent the day reading through the mailing list archives, Redhat documentation, and CentOS forums, and - to be frank - my head is now swimming with information. My scenario seems reasonably straightforward : I would like to have two file servers which mirror each others' data, then i'd like those two servers to act as a cluster, whereby they serve said data as if they were one machine. If one of the servers suffers a critical failure, the other will stay up, and the data will continue to be accessible to the rest of the network. I note with some trepidation that this might not be possible, as per this document : http://www.redhat.com/docs/manuals/enterprise/RHEL-5-manual/en-US/RHEL51 0/Cluster_Logical_Volume_Manager/mirrored_volumes.html However, i don't know if that document relates to the same scenario i've described above. I would very much appreciate any and all feedback, links to further documentation, and any other information that you might like to share.
