Combine all NVMs on AWS instance (e.g. i3) as raid0 and mount as data

nvmraid.sh

# https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/raid-config.html
nvmes=$(sudo lsblk | awk '/^nvme/ {printf "/dev/%s ", $1}')
sudo mdadm --create --verbose /dev/md0 --level=0 --name=my_raid --raid-devices=$(echo $nvmes | wc -w) $nvmes
sleep 10# crutch
sudo mkfs.ext4 -L my_raid /dev/md0
sudo mdadm --detail --scan | sudo tee -a /etc/mdadm.conf
sudo dracut -H -f /boot/initramfs-$(uname -r).img $(uname -r)
sudo mkdir /data
sudo mount LABEL=my_raid /data
sudo chown ec2-user:ec2-user /data/

Note that if using the above with AWS Batch, you will need to wrap the above in MIME.
