MKFS command can format ext 's,fat file system

Mkswap command to format swap partitions

Mkfs-t ext3/dev/sdb1(format a partition)

Mkfs-t vfat-f 32/dev/sdd6(formatted FAT32 file system)

MKSWAP/DEV/SDD5 (formatted swap partition)

LVM is a logical mechanism for the management of disk partition in Linux system, which is built on the hard disk and partition, a logical layer under the file system, which can dynamically adjust the disk capacity while keeping the original data unchanged.

/ Boot partitions cannot be created based on LVM and must be isolated

PV Physical Volume +VG Volume group +LV Logical Volume =LVM

PV: Physical volume is the most basic unit, usually corresponds to a piece of hard disk, or partition
