How To Expand an EBS Volume After a Disk Resize on Amazon Linux

Author: erics, April 17th, 2023

First, use the AWS Console to modify the volume to the desired size, in our example we want to go from 10GB to 25GB for the root filesystem For a Xen ext4 root volume

# df -h

/dev/xvda1      9.8G  9.6G   26M 100% /

How To Expand an NVMe EBS Volumes After a Disk Resize on Amazon Linux

If the XFS tools are not already installed, you can install them as follows:

sudo yum install xfsprogs

For an EXT4 filesystem, use the resize2fs command instead:

sudo resize2fs /dev/nvme0n1p1

1	sudo resize2fs /dev/nvme0n1p1

How To Expand a Filesystem on AWS Linux

Author: erics, March 6th, 2018

https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/recognize-expanded-volume-linux.html This only works on the new expandable volumes. YMMV, as always. 1. Examine file -s /dev/xvd* lsblk df -h 2. Grow partition Expand the modified partition using growpart (and note the unusual syntax of separating the device name from the partition number): growpart /dev/xvda 1 lsblk 3. Expand filesystem resize2fs /dev/xvda1 df -h
