[linux-lvm] LVM2 and RAID 1 not working on Fedora Core 2

I would recommend that you run LVM on top of the RAID.  I.E.  all of the disks
are setup for RAID (with partition type fd/"Linux raid auto") and then you make
the resultant /dev/md0 a physical volume in the LVM.  You can then create two
logical volumes for your boot and root partitions.

If the system is recently installed then a re-install is probably the quickest
way to go.

I'm not sure what this could be but I don't think its due to the disks actually
being too big.

Hope this is of some help,
