Is the problem that you've got 4 partitions & this prevents you form
making a 5th?
Because using LVM I would simply create a new partition and add it to
the volume group.
The contents *should* indeed remain intact if one simply deletes the
partition & recreates at the same starting point, yet larger. I'm sure
I've used parted as well as cfdisk for this sort of thing in the past,
yet hesitate to recommend either as I would fear making a typo with an

Yes, part of the problem is that I can't create a fifth partition.
However, even if possible, this wouldn't have been my ideal solution
anyway as it would negate some of the performance benefit gained from
having one huge partition over the whole array.
But my real question is, as I've reached the max partition for the msdos
partition table, can I migrate to a GPT partition table without losing
