How do I increase the size of the LVM logical partition?

Reference: (http://blog.csdn.net/t0nsha/article/details/7296851)

LVM (Logical volume management)

Execute DF command to view file system space consumption

The logical volume/dev/fedora/home of LVM has been found to occupy 96% of the space!!!

Then use the du command to view the file footprint

The analysis shows that the largest occupying file is the virtual machine image of gnome-boxes. Full 13g!

No large files can be deleted, only partition management.

I'm going to compress the/dev/fedora/swap partition and give/dev/fedora/home a bit of space

(TIP :Fedora's Installation manual recommends that the remaining space be fully divided into LVM after the boot and swap are separated.)

(I have a swap partition that has never been used, and the memory of the computer is 8G, and the swap partition is never used.)

LVM Management Commands:

Expansion:

First expansion of the LV re-expansion file system

Lvextend-l +100m/dev/vg1/lv1 Logical volume size increased by 100M

RESIZE2FS/DEV/VG1/LV1 file system to the size of the logical volume

Contraction:

First minus the file system again minus the LV (note order)

Umount/dev/vg1/lv1

E2fsck-f/DEV/VG1/LV1

RESIZE2FS/DEV/VG1/LV1 100M reduce file system to 100M

Lvreduce-l 100m/dev/vg1/lv1 reduce logical volume to 100M

Mount-a

Steps:

1. Compressing/dev/fedora/swap partitions

Umount/dev/fedora/swap

E2fsck-f/dev/fedora/swap

Resize2fs/dev/fedora/swap 1G

Lvreduce-l 1g/dev/fedora/swap

The swap partition was successfully converted to 1GiB.

Results:

Use the Pvscan command to view the remaining space

2. extending the/dev/fedora/home partition

Execute Lvextend-l +4.59g/dev/fedora/home

Resize2fs/dev/fedora/home

Results:

Use the DF command to view the space occupied by the file system

Logical Volume/dev/fedora/home has successfully changed from 16G to 21G!
