I'm trying to do an encrypted install of Server 12.04 with /home on a second encrypted drive.

I can't select 'use as: physical volume for encryption' but there's no prompt for either the passphrase or keyfile (I want a keyfile, the passphrase was just a test attempt). The partition keeps saying it's not active, even after I try to activate encrypted volumes. I don't get any options to pick a filesystem or mount point either.

How do I get the second encrypted drive to activate?
