Linux Disk Partition and Format Notes

Some basic tools

lsblk to list partitions (or list block devices) lsblk -f or blkid to list the UUIDs


parted

There would seem to be a number of partition tools for Linux CLI.
  • sudo parted -l - to see all available partition information
  • sudo parted /dev/sda - to partition the specific drive

When in parted:

  • print to see current partition information
  • mkpart help to list option
  • mklabel gpt to give drive label gpt
  • mkpart help mkpart to list specific help items on mkpart
  • mkpart primary ext4 0% 100% to make a partition that take the full optimised drive area
  • rm 1 to remove partition 1

Format

sudo mkfs.ext4 /dev/sda1 - to format the drive

Fstab

sudo vim /etc/fstab -to edit the boot disk mount table, remember to make matching mount point directories
