Extend Kali Linux File System After AWS EBS Volume Disk Resize

Within the AWS console, expand the disk space. Then SSH to the Kali Linux instance and perform the remaining steps listed below.

Show the file system type (ext4)

Central-InfoSec@kali-aws$ lsblk -f
 └─xvda1	ext4

List the block devices

Central-InfoSec@kali-aws$ lsblk
 xvda     202:0    0  100G  0 disk 
 └─xvda1  202:1    0   10G  0 part /

The size of the root volume reflects the new size, 100GB, the size of the partition reflects the original size, 10 GB. This must be extended before you can extend the file system.

Extend the partition

Central-InfoSec@kali-aws$ sudo growpart /dev/xvda 1

Check that the partition reflects the increased volume size

Central-InfoSec@kali-aws$ lsblk
 xvda     202:0    0  100G  0 disk 
 └─xvda1  202:1    0  100G  0 part /

Extend the file system

Central-InfoSec@kali-aws$ sudo resize2fs /dev/xvda1

Check that the file system was extended

Central-InfoSec@kali-aws$ df -h
 Filesystem      Size  Used Avail Use% Mounted on
 /dev/xvda1      100G   10G   90G  10% /
