How to Install Lustre on Ubuntu Server Latest

Lustre is an open-source distributed file system that is commonly used in high-performance computing environments. It is a scalable and reliable file system that provides high throughput and low latency performance. In this tutorial, we will guide you through the steps required to install Lustre on Ubuntu Server Latest.

Prerequisites

Before starting with the installation process, ensure that you have the following prerequisites:

• A fresh Ubuntu Server Latest installation
• A user account with sudo privileges
• Internet connectivity to download Lustre packages
• SSH access to the server

Step 1: Install Lustre packages

The first step is to install the Lustre packages on the Ubuntu server using the apt package manager. Open a terminal window and run the following command:

sudo apt-get update
sudo apt-get install lustre-utils lustre-modules-dkms -y

The lustre-utils package provides the Lustre command-line tools, and lustre-modules-dkms package provides the kernel modules needed to enable Lustre file system.

Step 2: Configure Lustre

Once the Lustre packages are installed, the next step is to configure the Lustre file system. There are two types of configurations that need to be done: server and client configurations.

Server Configuration

To configure Lustre server, follow the steps below:

1. Open the /etc/ldev.conf configuration file using your favourite text editor:

   sudo nano /etc/ldev.conf
   

2. Add the following lines to the file:

   devices {
     device lustre_md {
       uri lustre://$HOSTNAME/mdt
       target /mnt/mdt
     }
   
     device lustre_ost {
       uri lustre://$HOSTNAME/ost
       target /mnt/ost
     }
   }
   

   We are creating two Lustre devices: lustre_md for metadata and lustre_ost for data storage.

3. Save and close the file.

4. Run the following command to create the metadata target:

   sudo mkfs.lustre --mgs /dev/lustre_md
   

5. Run the following command to create the object storage target:

   sudo mkfs.lustre --ost --mgsnode=$HOSTNAME@tcp0 /dev/lustre_ost
   

   Replace $HOSTNAME with the hostname of your server.

Client Configuration

To configure Lustre client, follow the steps below:

1. Open the /etc/fstab configuration file using your favourite text editor:

   sudo nano /etc/fstab
   

2. Add the following lines to the file:

   # Lustre File System
   lustre://$SERVER_HOSTNAME/mdt /mnt/lustre lustre noauto,x-systemd.automount,_netdev 0 0
   

   Replace $SERVER_HOSTNAME with the hostname or IP address of your Lustre server.

3. Save and close the file.

Step 3: Mount Lustre File System

After the Lustre file system has been configured on both server and client, it's time to mount it on the client system. Run the following command to mount the Lustre file system:

sudo mount /mnt/lustre

The file system will now be mounted on /mnt/lustre.

Conclusion

Congratulations! You have successfully installed and configured Lustre file system on Ubuntu Server Latest. You can now start using Lustre on your cluster for high-performance data storage and access.

If you want to self-host in an easy, hands free way, need an external IP address, or simply want your data in your own hands, give IPv6.rs a try!
