Linux Disk Partitions

This is little bit deep into Linux disk partitioning. Linux servers are attach with storage devices. These storage devices divided into partitions, which are logical sections of a physical disk.

Available partition types

Primary Partition: The main partitions (maximum up to 4 in MBR).

Extended Partition: Used to create multiple logical partitions (in MBR).

Logical Partition: Inside an Extended Partition explained above (in MBR).

GPT Partitions: Used in modern systems, supports 128 partitions (in GPT).

Swap Partition: Used for virtual memory (disk storage as memory).

Lets learn about these words.

When we connect a disk (storage) to a linux server/host, linux server identifies it as a file (In Linux world everything is a file).

Here I am not going to talk about root disk (/dev/vda is the root disk). So I am assuming a use case, we need a additional storage called new Disk of 1GB. You can execute lsblk command to monitor attached disks.
