[SOLVED] how to I expand the GPT after expanding raid?

I expanded my hardware raid from 4.5 to 6 TB.

Parted sees the 6TB but all operations fail that try to use the new space.

If I try ro create a new partition with that space it gives me an error that says the GPT needs to be resized.

So how do I non-destructively grow the partition table to fill the whole "disk"?

I *finally* solved this.

The magic trick was to just type "#parted /dev/sdb" I'd always been running it like "#parted /dev/sdb1"

When I ran it against "/dev/sdb" and did a print command it gave me the "do you want to fix the GPT?" - I had to tell it twice to fix the GPT and that was that.

Problem solved. I now have a 6TB partition with the data intact.
