I had created a separate LUKS volume on each hdd, then I added them to LVM2
by crating a separate VG for each hdd, with no additional encryption ( I
believe that's called layered encryption ). I then in one VG ( which is the
2nd VG for the system ) created 3 or 4 LVs using one for the 2nd half of my
swap totalling 5GB and the othe VG only has 1 LV. I had done all this with
Fedora 12. When I finally got Fedora 13 to install I must have missed the
part that would have allowed to non-destructively include other hdds in the
new system. Now when I boot the drive that has F 13 the 2 1TB hdds don't
exist. fdisk -l only shows the 1st drive (/dev/sda) partitions and the boot
process of course only unlocks 1 key0 slot. However the LVM GUI
(system-config-lvm) does show /dev/sdb and sdc as uninitialized drives. I
did just stumble onto a similar comment on Ubuntu just before reading your
comment/suggestion and it is very similar to yours with a little more
detail. I plan on giving that a try. I'll let you know what happens.

In the meantime, anyone that is planning to install Fedora 13 and you have a
Gigabyte MoBo you might want to check the following threads at
