How do I make Ubuntu's resize2fs command work after increasing Droplet size?
Earlier today I increased the drive space on my Ubuntu droplet from 30GB to 40GB. After restarting, the drive size has increased:
> fdisk -l ... Disk /dev/vda: 40 GiB, 42949672960 bytes, 83886080 sectors
But naturally the filesystem itself is still 30GB:
> df -h ... /dev/vda1 30G 16G 13G 55% / > fdisk -l ... /dev/vda1 * 2048 62910539 62908492 30G 83 Linux
The problem is that the resize2fs command doesn’t behave as expected.
> sudo resize2fs /dev/vda1 resize2fs 1.42.12 (29-Aug-2014) The filesystem is already 7863561 (4k) blocks long. Nothing to do!
Have I missed a step here? As I understand it, I should be able to increase the size of the root filesystem without unmounting it. Is there something I need to do to the partition table to tell resize2fs that the additional 10GiB is there for the taking?
Any suggestions would be much appreciated!
