Upgrade Lustre client software to the current version

  • Article

In this article, you learn how to upgrade an existing Lustre client package to the current version. Upgraded client software is required to connect to an Azure Managed Lustre file system.

If you need to install the client software for the first time, see Install prebuilt Lustre client software.

For more information on connecting clients to a cluster, see Connect clients to an Azure Managed Lustre file system.

Upgrade a Lustre client

If your client machine uses an older version of Lustre, you can upgrade the Lustre client package to the current version by using the following steps. It's important that you completely uninstall the previous Lustre client's kernel modules, in addition to removing the client software packages.

  1. Unmount any containers or mount points that are mounting the Lustre client by using the following command:

    sudo umount <all Lustre mounts>

  2. Uninstall the existing Lustre client version by using the following command:

    sudo dnf remove *lustre*

  3. Install the current version of the Lustre client by using the following command:

    sudo dnf install amlfs-lustre-client-2.15.6_39_g3e00a10-$(uname -r | sed -e "s/\.$(uname -p)$//" | sed -re 's/[-_]/\./g')-1

  4. Unload the Lustre and Lustre Networking (LNet) kernel modules by using the following command:

    sudo lustre_rmmod

  5. Verify that old kernel modules are removed by using the following command:

    cat /sys/module/lustre/version; lsmod | grep -E 'lustre|lnet'

    The output should look similar to the following example:

    cat: /sys/module/lustre/version: No such file or directory

    If the output shows an old version of the Lustre kernel module, we recommend that you restart (sudo reboot) the system.

After you perform this procedure, you can mount the client to your Azure Managed Lustre file system.
