parted

GNU Parted - a partition manipulation program

Used by OpenELEC to create SD card partitions: (create_sdcard)

DISK = /dev/sdh

# writing new disklabel on $DISK (removing all partitions)...
parted -s /dev/sdh mklabel msdos

# creating partitions on $DISK...
parted -s "$DISK" unit cyl mkpart primary fat32 -- 0 16
parted -s "$DISK" unit cyl mkpart primary ext2 -- 16 -2

# make partition active (bootable)
parted -s "$DISK" set 1 boot on

# tell kernel we have a new partition table
partprobe "$DISK"

# create filesystem
# creating filesystem on $PART1...
mkfs.vfat "$PART1" -I -n System
# creating filesystem on $PART2...
mkfs.ext4 "$PART2" -L Storage

# sync disk
sync

Larger than 2TB RAID

To get larger than 2TB you need GPTs

parted /dev/sdb
 mklabel gpt
 print free
 mkpart primary 1M 4TB
 p
 set 1 raid on
 align-check optimal 1
 q

mdadm --create --verbose /dev/md0 --level=5 --raid-devices=4 /dev/sd[iklm]1

mkfs.ext4 /dev/md0 -L /ci

cat /proc/mdstat

---

parted -a optimal /dev/sdf
