I mean: What if both hosts update the same sector? host A updates his local disk host B updates his local disk host B updates host A's local disk host A updates host B's local disk Then the mirror would be not in sync... Furthermore a file system like UFS does not like multiple read/write mounts (as far as I know)... Maybe AFS or arla/coda6_server/coda6_client from ports/net or so is more what u want? -Arne __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo!
