I had an Ubuntu VM which I imported into Amazon AWS. I then increased the volume size from 100GB to 1500GB.

How can I extend the partition to use all of the new space.

root@pbx-a:~# lsblk
NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT
xvda 202:0 0 1.5T 0 disk
├─xvda1 202:1 0 97.4G 0 part /
└─xvda2 202:2 0 2.6G 0 part [SWAP]


root@pbx-a:~# df

/dev/xvda1 100414960 34551944 61265148 37% /

Thanks

You first need to resize the actual xvda1 partition, eg. with parted. Because xvda2 is in the way, you'll need to disable it (swapoff /dev/xvda2), then remove it or move it during the re-partitioning process, and re-create it if removed and re-enable swap later if desired. Once xvda2 is no longer positioned immediately after xvda1, parted should simply let you resize xvda1 to fill the free space in between.

As for how to use parted, you usually want to start with print to show the current state of the partition table. If you want to move xvda2, simply run move 2 and, looking at the numbers from the partition table, input the new start and end positions for partition move has been removed in later versions of parted, so just remove partition 2. After this, use resizepart 1 to resize partition 1 to the desired final size. If you left free space after partition 1, you can recreate xvda2 by running mkpart to create a new partition.

At this point, you should reboot so the partition table gets updated.

After this, assuming the partition on /dev/xvda1 is ext2, ext3 or ext4, running resize2fs /dev/xvda1 as root will automatically resize the partition to be as large as possible. For other types of partition live resizing might or might not be possible - for instance, with btrfs you would use btrfs filesystem resize max / to live-resize the filesystem mounted at / to its maximum available size.
