As DRDB is mentioned there, GlusterFS comes into my mind. Although it is a
different concept than iSCSI or NFS it might be the better way to have 2
redundant filesystems on each server. Or maybe Qemus qemu-nbd (QEMU Disk
Network Block Device Server) might help.

But most importantly I would use a good hardware RAID with SAS HDs.
