[ubuntu-us-mi] creating a GPT disk label

[Robert Citek]

How does one specify to the Ubuntu installer to create a GPT disk
label instead of an MSDOS label when installing Ubuntu server?

I would like to install Ubuntu on some servers and have the disks on
the servers use the GPT disk label. Unfortunately, I have not been
successful in creating a GPT disk label using the server CD.

My current method is to boot with the Ubuntu desktop CD, type 'sudo
parted /dev/sda mklabel gpt' in a terminal, and reboot, swapping out
the desktop CD for the server CD. That works, but I find it rather
cumbersome. I've tried booting the server CD, exiting to a shell, and
typing parted. But apparently parted is not on the server CD or is
not available via busybox. I also tried fdisk, but it does not
support creating GPT labels.

Is there a way to create a GPT disk label using the server CD?

A possible alternate solution might be to do a "normal" install, boot
into the new system, and convert the MSDOS label to GPT using gdisk.
Has anyone tried doing this?

Using gdisk seemed to work. However, I had to reinstall grub using
'grub-install --force /dev/sda'

Using gdisk to resize a partition worked well, too. Actually, to
resize I had to delete and create new. But it worked. I just made
sure the start sectors were identical. Rebooted and then did a
pvresize.
