How to Increase Disk Space?

Increase disk space when SSH using root.

Check the current partition size using

df -h

Check the actual physical disk size and available partition using the following command:

fdisk -l

Example of output:

Filesystem Size Used Avail Use% Mounted on
/dev/vda1  30G  3.2G 2.5G  12%   /

The example above shows the disk is /dev/vda and the partition is 1.
Install using cloud-utils-growpart command and press y to continue the installation. You should see Complete! At the end of the installation process.

yum install cloud-utils-growpart

Use the following command to grow the logical partition to extend to all available space:

growpart /dev/vda 1

Example of output:

CHANGED:partition=1 start=2048 old:size=41938688 end=41940736 new:size=62912479,end=62914527

The output might be different based on your disk space.
Run resize2fs command to extend filesystem:

resize2fs /dev/vda1

Example of output:

resize2fs 1.42.9 (28-Dec-2013)
Filesystem at /dev/vda1 is mounted on /; on-line resizing required
old_desc_blocks = 3, new_desc_blocks = 4
The filesystem on /dev/vda1 is now 7864059 blocks long.

The output might be different based on your disk space.
Check your new partition size:

df -h

You should see the size of your partition and filesystem has been increased.
