[chbot] Urgent help with disk partitioning

[Blair Inglis]

g for new gpt table
n for new partition (creates a linux partition)
t to change type, 29 is linux raid
w to save and exit

there's a guide on the-geek-diary.com that says to use sfdisk to copy a
good disks table to the new disk before rebuilding the array.

check mdadm --detail to see if its rebuilding (prob take ages)
