For this example, suppose that you have an instance built on the Nitro System, such as an M5 instance. You resized the boot volume from 8 GB to 16 GB and an additional volume from 8 GB to 30 GB. Use the following procedure to extend the file system of the resized volumes.
To extend the file system of NVMe EBS volumes
To verify the file system for each volume, use the df -hT command.
The following is example output for an instance that has a boot volume with an XFS file system and an additional volume with an XFS file system. The naming convention
/dev/nvme[0-26]n1indicates that the volumes are exposed as NVMe block devices.
Filesystem Type Size Used Avail Use% Mounted on /dev/nvme0n1p1 xfs 8.0G 1.6G 6.5G 20% / /dev/nvme1n1 xfs 8.0G 33M 8.0G 1% /data ...
To check whether the volume has a partition that must be extended, use the lsblk command to display information about the NVMe block devices attached to your instance.

This example output shows the following:
