I recently had the need for very fast storage on an Amazon AWS machine. I gave a try to their “NVMe Storage Optimized” instances. I was a bit surprised though that the drive was not accessible straight away. To make it work, you need to format and mount it manually.

Formatting the drive found at /dev/nvme0n1:

$ sudo mkfs -t ext4 /dev/nvme0n1

Mounting to /ebs/:

$ sudo mkdir /ebs
$ sudo mount -o rw /dev/nvme0n1 /ebs/
$ cd /ebs/
