Select an instance and click Instance state. Choose Stop Instance.
After the instance has been stopped, go to the Storage tab and click the Volume ID. It will take you to the Volume configuration.
Tick the checkbox next to the Volume ID and click Actions. Select Modify volume.
The previous size of my volume is 30GB. I resized it to 60GB.
Click Modify.
Ssh to your instance and type in df -h. In my volume, it can be seen below that it is now 60GB in size /dev/nvme0n1p1.
The volume that I have doesn’t need to expand the partition because it was automatically expanded. You might encounter that the partition is still the size of the original volume. For example, my original volume is 30GB, when I resized the volume to 60GB, the partition stayed at 30GB. To fix that, just type
growpart /dev/nvme0n1 1
If it’s already expanded, you get the message that it cannot be grown.
