I'm not comfortable with switching from MS-DOS to GPT disklabels on a
running production server, and nothing in the Ceph docs at the time
mentioned that GPT was a requirement on the journal disks.
Switching to GPT isn't toggling an option, it'd require resizing
partitions (some of these are xfs; can't be shrunk to my knowledge) and
moving stuff around to allow for an additional EFI boot partition,
possibly changes to boot firmware settings and bootloaders too.
I'll look into a udev rule for our particular case and see how I go.
