You'll have to load the firewire module with exclusive_login = 0, and then both servers will happily share that $150 fw disk ;-) and it actually works well enough to run Xen VMs off shared disk, using OCFS2 in userspace heartbeat mode, with Heartbeat2 managing the VMs as resources. There's some setup info here: http://www.oracle.com/technology/pub/articles/hunter_rac10gr2.html > Given how little you seem to be using heartbeat, perhaps the drbd or > ocfs2 lists might be a more appropriate forum. > >> The concept is great an active/active disk partition and heartbeat with no >> fancy SAN's.

I haven't checked prices recently, but multi-initiator serial attached shared SCSI is also a recent option, with a number of vendors providing low cost RAID enclosures, that can be shared across more than the shared firewire disk limit of two nodes.
