setup-storage and partitions greater than 2Tb

[George Barnett]

I realise I left off some data:

Setup Storage config:

disk_config sda disklabel:gpt-bios align-at:1
primary / 10G ext3 rw createopts="-m 0" tuneopts="-c 0 -i 0"
primary swap 6G swap sw
primary /e 0- ext4 rw,errors=remount-ro,nosuid,noatime,nobarrier createopts="-m 0 -b 4096 -J size=1024 -E stride=16,stripe-width=176" tuneopts="-c 0 -i 0"



Parted:
Model: LSI MR9260CV-4i (scsi)
Disk /dev/sda: 3293837262848B
Sector size (logical/physical): 512B/512B
Partition Table: gpt
Number Start End Size File system Name Flags
