So what you do is you LUKS the raw parition, get a decrypted 
partition and place ACFS in that. The second machine never
knows, as it can access the data only though ACFS.

I can imagine that I can setup LUKS from one node but I don't know what should be done on second node. For example when I restart first node pass the passphrase for LUKS during the boot process for shared partition, system start up with encrypted partition. But what happen when I try to restart the second node.
