AWS CentOS Resize Disk

How to Resize a Disk from AWS CentoOS Image

 

Then create a new AMI. On boot, the cloud-init "growpart" module will grow the root partition to the total EBS size. Clearly, if that's not what you what, change or ignore that advice.

# fdisk /dev/xvda <<END
u
d
n
p
1
2048
w
END
# reboot
# (after reboot)
# resize2fs /dev/xvda1
# df -h / # should now be entire EBS volume
