How to auto mount NVMe EBS Volumes on EC2?

How to auto mount NVMe EBS Volumes on EC2?

In this tutorial, we’re going to mount an NVMe EBS volume to an EC2 instance and add it to /etc/fstab so it automatically mounts the volume after reboots.

First list block devices using lsblk:
sudo lsblk

You will see a result similar to this:

List block devices in order to see all available NVMe devices<br>

List block devices in order to see all available NVMe devices

The NVMe volumes names follow the pattern below:

/dev/nvme0n1
/dev/nvme1n1
/dev/nvme2n1
.
.
.
/dev/nvme\[0-26\]n1
Enter fullscreen mode Exit fullscreen mode

Then build a Linux file system of your choice, I picked ext4 here:

sudo mkfs -t ext4 /dev/nvme1n1
Enter fullscreen mode Exit fullscreen mode

Verify the build using the file command and copy the UUID value:

sudo file -s /dev/nvme1n1
Enter fullscreen mode Exit fullscreen mode

The result is something like this:
/dev/nvme1n1: Linux rev 1.0 ext4 filesystem data, UUID=<br>

/dev/nvme1n1: Linux rev 1.0 ext4 filesystem data, UUID=

Now edit /etc/fstab with the editor of your choice (I prefer nano xD) and add the following line to it:

UUID="<copied-uuid-value>" <mount-directory-path> ext4 defaults 0 0
Enter fullscreen mode Exit fullscreen mode

Now we use the mount utility to verify and mount the volume.

sudo mount -a
Enter fullscreen mode Exit fullscreen mode

You can checkout your mounted volumes using:

The result is something like this:
