Disk partitions in Linux
- In x86 architecture, there are maximum 4 primary partitions on a hard drive.
/dev/sda1
/dev/sda2
/dev/sda3
/dev/sda4
One of them can be of "extended" type and doesn't contain a file system, but can contain logical partitions. Say,
/dev/sda1 - primary
/dev/sda2 - extended
/dev/sda5 - logical
/dev/sda6 - logical
/dev/sda7 - logical
Max number of logical partitions is 12. Their sequence number can not be skipped, unlike that for the primary partitions.
fdisk, cfdisk, gdisk, and parted can be used for partitioning a drive,
Each partition type is assigned a unique code, for example
0x06 - FAT
0x82 - Linux swap
0x83 - Linux filesystem
File systems can be created with mkfs command
To create a swap partition, use mkswap
