If you just create a volume, you can attach it to the ec2

List available devices to find your new volume

lsblk

1. Format the new volume with xfs:

sudo mkfs -t xfs /dev/nvme1n1 (make sure the name is correct)

2. Create a mount point

sudo mkdir /data

3. Mount the volume

sudo mount /dev/nvme1n1 /data

4. Make it permanent by adding to fstab

echo "/dev/nvme1n1  /data  xfs  defaults,nofail  0  2" | sudo tee -a /etc/fstab
