Problems with partitioning in Fedora installation
I have four HDDs in my machine -- sda, sdb, sdc, sdd -- and I'd like to install Fedora onto a logical volume extending over most of sda and sdb. I say most because I need to have a separate /boot partition on sda which is *not* part of the logical volume (it has to be that way for my machine to boot).
The problem I am having is that Fedora (and PCLinuxOS) seem to think sda and sdb are one single disk, and will only let me install to that giant disc. This would be fine, but, since /boot is on this disc, the machine can't boot.
The installers recognise sdc and sdd as separate discs, and they even recognise that they are part of another logical volume, but no matter how I configure sda and sdb it still thinks they're one giant disc. I've tried blanking them, I've tried setting up the partitions and logical volumes with a liveCD, and I've made sure that they're not set as a software RAID in my BIOS, but nothing will convince Fedora or PCLinuxOS that these are separate hdds.
Can anyone help me understand this?
(BTW: Ubuntu and openSuse recognise the hdd as four separate discs, so I don't think this is a hardware issue. Unfortunately Ubuntu and OpenSuse aren't good options for me at the moment.)
