When you create your pool using GPT labels, it will prefer them over
anything else on import. If it cannot find labels, it will switch to
something else that looks like your VDEVs.

If you want to switch to GPT labels when your pool already exist and you
cannot export it (it holds root file system), you can create GPT labels
with gpart(8), disable GPTIDs by adding the following line to
/boot/loader.conf:

	kern.geom.label.gptid.enable=3D0

Then you reboot and hope for the best. It will either pick GPT labels or
ada<X>p<Y>.
