Paul,

I saw on the Linux HA site that version 2 supported more than 2 hosts, 
but I couldn't find documentation for it anywhere. Is there any 
documentation or examples for this that anyone knows about? Is anyone 
using this for more than 2 nodes?
I've got no issues on the storage side, it's just automatically 
restarting the VMs in the case of node failure that I am after.
Thanks,
Jeff
