[ale] VLM & LUKS

[skotchman at gmail.com (Scott Castaline)]

I am in the process of changing out a 500GB for a 1TB. When I had 
originally installed Fedora 12 I created three volume groups, using LUKS 
on all 3. I had also created 2 swap files as LUKS logical volumes split 
between 1st and 2nd VG. The hdd change is the 3rd VG and it only has 1 
lv. I had removed the original 500gb from LVM and then did the physical 
switching around the drives. I have now recreated the 3rd VG with 1 LV 
on the new 1TB.

I had first ran smartctl short and long on it and now I'm running 
mkfs.ext4 -c -c on it. Once that is done what do I need to do to enable 
it as a LUKS volume? I would also like to use my global passphrase for 
my other LUKS volumes, is that possible after the fact?
