formatting a 12.73 Tb disk on ROCKS 5.2

[Doll, Margaret Ann]

The answer came from my vendor at Atipa.

You will need to change the partitioning scheme to use GPT in order to
enable greater than 2TB support.



# parted -s /dev/sda mklabel gpt

# parted –s /dev/sda rm 1

# parted –s /dev/sda “mkpart primary xfs 1 -1”



At this point, you should be able to continue as you were trying to do
before.



# mkfs.xfs /dev/sda1
