    Study Notes

    Partition Table and Partitioning

    • Partitioning is the process of dividing a storage device into multiple partitions.
    • The partition table contains information about the partitions, including the range of sectors used by each partition.

    Partition Table Types

    • MBR (Master Boot Record) partition table supports disks up to 2TB in size and allows for:
      • Up to 4 primary partitions (where an OS can be booted from)
      • One of the primary partitions can be an extended partition
      • Extended partition is a container for logical partitions (used for data storage)

    Devices and Partitions in Linux

    • Devices in Linux can be found under the /dev directory.
    • Disks and partitions follow specific naming conventions:
      • SATA/SCSI storage devices are named /dev/sdX where X is the device letter (e.g., /dev/sdd is the 4th storage device)
      • Partitions on a storage device are numbered /dev/sdXN where N is the partition number (e.g., /dev/sdb3 is the 3rd partition on the 2nd storage device)

    Partitioning in Linux

    • The fdisk program can create partition tables and partition disks.
    • A usage example is available on the Linux Documentation Project.

    File Systems

    • Creating a partition using fdisk only divides the space on a disk; it doesn't create a file system.
    • A file system is needed to store content inside the partition.
    • A file system is a way of storing content inside a disk partition, and there are many types of file systems, each with different characteristics.
    • Linux supports a huge number of file systems.

    Creating a File System

    • Use mkfs to create a file system on a partition.
    • Example: mkfs -t ext4 /dev/sda1 creates an ext4 file system on the 1st disk, 1st partition.

    Mounting a File System

    • Use mount to mount a file system.
    • The fstab file contains information about the file system, including the device name, mount point, and options.
    • Example: mount /dev/sda1 mounts the file system on the 1st disk, 1st partition.

    Swap Partitions

    • A swap partition is used to hold memory pages for Unix/Linux Virtual Memory.
    • The swap partition needs to be created and initialized using fdisk and mkswap.
    • Example: mkswap /dev/sdb9 initializes a swap partition on the 2nd disk, 9th partition.

    Virtual Memory

    • Virtual memory is implemented using swap partitions.
    • Swap partitions are usually only one per system, but systems with a lot of memory may have more.

    Creating and Using Swap Partitions

    • Step 1: Create the partition using fdisk.
    • Step 2: Initialize the swap area using mkswap.
    • Step 3: Connect the swap area to the system using swapon.
    • Use swapon -s to display currently active swap partitions.
    • Use swapon -a to connect all swap partitions listed in fstab.

    Choosing a File System Type

    • Journalling file systems (e.g., ext4) are more resistant to corruption due to sudden power loss.
    • Use mkfs with the -t option to specify the file system type (e.g., mkfs -t ext4 /dev/sda1).

    File System Organization

    • The file system organization is as follows:
      • /opt: Optional software, installed outside the package management system.
      • /proc: Virtual file system, can be used to read kernel and process information.
      • /root: The home directory for the root account.
      • /sys: Virtual file system, information on the system and its components.
      • /tmp: Temporary files, for short-term storage.
      • /usr: Operating system, application, and documentation files.
      • /usr/bin: User commands applications, can be executed by regular users.
      • /usr/sbin: Admin commands applications, need to be root to run.
      • /var: Files expected to be changing often (variable content).
