Installation

  • sudo apt install parted in debian

Useful parted cli commands:

  • print - print the full configuration.
  • select DEVICE - to change to a different device and edit it.
  • mklabel gpt - to create a gpt label for the partition
  • mkpart primary btrfs 1MiB 100% - to create a partition of type primary with format btrfs starting at 1MiB and ending at 100% or end of the disk.

  • `` Useful other disk management commands:

  • lsblk and fdisk -l shows disk configuration for all the disks.
  • sudo mkfs.btrfs -f /dev/sda1 to create the final btrfs partition for sda1 partition. This is not always needed if parted does it by default.

Validate settings:

  • df -h to show all the mount location.

User management:

  • sudo useradd -m -d /home/subho -s /bin/bash -G standard,admin subho to add user subho with home location /home/subho, default shell as bash and add to group standard,admin.
  • sudo passwd subho to change or create password for user subho.

Permanent Mount

  • To mount a drive during restart one need to make the mount entry to /etc/fstab
  • Obtain the UUID from lsblk -f or sudo blkid
  • UUID=0f2b8e50-94c0-4385-abed-ce020da2555b /fast btrfs defaults 0 0 something of this format
  • systemctl daemon-reload in debian to reload the fstab settings
  • To temporary mount use sudo mount /dev/sdb1 and to unmount sudo umount /mnt/loc
