Currently, FreeBSD does not offer any solution for direct shared block 
devices for write access, since there is no shared/clustered filesystem 
in FreeBSD.  You could use NFS, which would probably work ok for you, or 
have both hosts reading from the same disks, but writing to the same 
shared array (via fibre channel for instance) won't work currently.
