Logical Volume Manager (LVM) can be used to stripe multiple disks together to form a single logical volume. If striping disks together is not a requirement, skip these steps.

Find disk that already has a partition

used_disk=$(lsblk -P -I 259 | grep "nvme.n1.*part" | grep -o "nvme.n1")

Create array of free disks

declare -a free_disks
mapfile -t free_disks < <(lsblk -P -I 259 | grep "nvme.n1.*disk" | grep -o "nvme.n1" | grep -v "$used_disk")

Get quantity of free disks

free_disks_qty=${#free_disks[@]}

Construct pvcreate command

cmd_string=""
for i in "${free_disks[@]}"
do
  cmd_string="$cmd_string /dev/$i"
done

Initialize disks for use by LVM

pvcreate_cmd="pvcreate $cmd_string"
$pvcreate_cmd

Create volume group

vgcreate_cmd="vgcreate hdb_vg $cmd_string"
$vgcreate_cmd

Create logical volume

lvcreate -n hdb_lv -i $free_disks_qty -l 100%FREE hdb_vg

Run lsblk and note the device name of the additional volume

lsblk

Create an ext4 filesystem on the volume (The below commands assume the device name is nvme1n1. If you used LVM to create logical volume, replace /dev/nvme1n1 with /dev/hdb_vg/hdb_lv)

sudo mkfs.ext4 -L hdb_data /dev/nvme1n1

Mount the file system and set the correct permissions for the directory

mkdir /home/ubuntu/hdb
sudo mount -t ext4 /dev/nvme1n1 /home/ubuntu/hdb
sudo chown -R ubuntu:ubuntu /home/ubuntu/hdb
sudo chmod 775 /home/ubuntu/hdb

Create a fstab entry to mount the filesystem on boot

echo "LABEL=hdb_data /home/ubuntu/hdb ext4 defaults,noatime 0 1" | sudo tee -a /etc/fstab

If a swap file or partition does not already exist, create and enable a 2GB swap file

sudo dd if=/dev/zero of=/swapfile bs=128M count=16
sudo chmod 600 /swapfile
sudo mkswap /swapfile
sudo swapon /swapfile
echo "/swapfile swap swap defaults 0 0" | sudo tee -a /etc/fstab

Increase the open file limits for the ubuntu user

echo "ubuntu soft nofile 500000" | sudo tee -a /etc/security/limits.conf
echo "ubuntu hard nofile 1000000" | sudo tee -a /etc/security/limits.conf

Verify Python v3.5, v3.6, v3.7, or v3.8 is installed.

python3 --version
