Tried this just now. Spun up 8GB ec2+ebs instance. Booted and logged in as root. Deleted the root partition using fdisk, carefully recreated it from the same starting sector but to new 100GB capacity (check lsblk output to confirm). Then resize2fs /dev/xvda1 my ext4 FS. All online, hot. Obviously it's risky, but you can take a snapshot of the EBS before starting. Seems very nice for the common use case of slowly growing storage needs that are best served by a simple disk. |
