Thanks Dennis. I think you pointed me in the right direction. The solution seems to have been to not worry about setting the partition ID to 8e (LVM). I used GNU parted to create one big 2.5TB partition of type GPT. I then just used the LVM commands to create the physical, virtual, and logical volumes which went without a hitch. Finally, I formatted the 2.5TB LVM partition with mkfs.ext3 which seems to have worked. Here's roughly what I did in case anyone needs a cheat sheet: # parted /dev/sdb (parted) mklabel gpt (parted) mkpart primary 0 2.5T (parted) quit # pvcreate /dev/sdb1 # vgcreate myvolume /dev/sdb1 # lvcreate -L 2.5TB myvolume # mkfs.ext3 /dev/mapper/myvolume-lvol0 Thanks again, Tom On 2/4/07, Dennis Gilmore <dennis@xxxxxxxx> wrote:

One big issue to note is that you can not boot from a disk labeled with gpt labels.
