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:
The NVMe volumes names follow the pattern below:
/dev/nvme0n1
/dev/nvme1n1
/dev/nvme2n1
.
.
.
/dev/nvme\[0-26\]n1
Then build a Linux file system of your choice, I picked ext4 here:
sudo mkfs -t ext4 /dev/nvme1n1
Verify the build using the file command and copy the UUID value:
sudo file -s /dev/nvme1n1
The result is something like this:
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
Now we use the mount utility to verify and mount the volume.
sudo mount -a
You can checkout your mounted volumes using:
The result is something like this:
