You can't mount the same UFS filesystem on two servers at once.  You'll
end up with a horribly-corrupted filesystem, since neither one is aware
of changes the other makes. You would need a shared-storage cluster
filessytem to be able to do that (or mount the volume read-only on both
servers).  

Mount the filesystem on one server only, then access it via NFS from
the other.
