How would I go about changing a guid of a zfs physical device? There
doesn't seem to be any options in zpool or zdb for doing guid changes.
It's a long story, but through a series of drive swaps I've managed to
really screw stuff up.
Here's my current status

14791054479353866913 is really /dev/ada1s4 now
5249816505308091368 is really /dev/ada0 now
the problem is, zdb tells me that /dev/ada1 has a guid of
3184618752700174674
and zdb says /dev/ada0 has a guid of 16592948394566938185
I need to get these to match so that I can reconstruct the pool again
