Tutorial: How to install Lustre on Arch Linux

Lustre is an open-source parallel distributed file system designed for use in large-scale cluster computing environments. In this tutorial, we will walk you through the steps to install Lustre on Arch Linux.

Prerequisites

• A fresh installation of Arch Linux
• Root access or sudo privileges
• Basic knowledge of Linux command-line interface

Step 1: Update System

Before installing Lustre on Arch Linux, it is recommended to ensure the system is up-to-date. To update the system, run:

sudo pacman -Syu

Step 2: Install Required Packages

Lustre requires a few packages to be installed on the system before it can be installed. The required packages are:

• linux-lts - A long-term support kernel
• lustre-utils - Includes various utilities to manage Lustre
• lustre-modules-lts - The kernel-module

To install these packages, run:

sudo pacman -S linux-lts lustre-utils lustre-modules-lts

Step 3: Configure /etc/ldev.conf

Ldev.conf needs to be created or edited for use on the server. To create or edit the configuration file, run:

sudo vi /etc/ldev.conf

Insert the following into the file:

metadata-pc0 /dev/sdb1
metadata-pc1 /dev/sdc1
object-pc0 /dev/sdd1
object-pc1 /dev/sde1

Save the changes and exit the editor.

Step 4: Mount the Lustre File System

To mount the Lustre file system, you need to create a mount point for the file system. For this tutorial, we’ll create a mount point at /mnt/lustre:

sudo mkdir /mnt/lustre

Run the following commands to mount the Lustre file system:

sudo mount -t lustre /dev/sdb1 /mnt/lustre

Step 5: Mount at boot

To have the Lustre file system mounted at boot, add the following line to /etc/fstab:

/dev/sdb1 /mnt/lustre lustre defaults,_netdev 0 0

Step 6: Test the Lustre File System

To test that the Lustre file system has been mounted correctly, create a file in the mount point:

sudo touch /mnt/lustre/testfile

Verify the file has been created by running:

ls /mnt/lustre

If the file is present, congratulations, you have successfully installed Lustre on Arch Linux.

Conclusion

In this tutorial, you learned how to install Lustre on Arch Linux. Lustre is an essential component for distributed file systems, and by following the above steps, you should be able to install Lustre and have a base to build an efficient Lustre cluster.
