Vast Repo and Vast Client Installation

This section describes the steps to build the Vast repository and install the Vast client on the cluster nodes.

Note

The Vast repository must be hosted on an HTTP server (such as Apache) before it can be used as a user repository in Omnia.

Step 1: Download Vast

Download the Vast package using the following command:

curl -sSf https://vast-nfs.s3.amazonaws.com/download.sh | bash -s --

Step 2: Extract the Package

Extract the downloaded tarball:

tar -xf vastnfs-4.5.5.tar.xz vastnfs-4.5.5/
../../../_images/vastrepo2.png

Step 3: Build the Vast Repository

Navigate to the extracted directory and build the repository:

cd vastnfs-4.5.5/
./build.sh bin
../../../_images/vastrepo3.png

Once the build is complete, you will see a message indicating that the RPM files have been created and are ready to be hosted as a user repository.

The Vast RPMs will be located in the dist/ directory within vastnfs-4.5.5/.

Step 4: Host the RPMs on an HTTP Server

Host the RPMs on an HTTP server (such as Apache) or any other server that will serve as your user repository.

For example, you can use the OIM as an HTTP server. Follow the steps provided in the documentation for hosting Slurm repositories on the Apache server (refer to Host the RPMS on the Apache server).

Step 5: Configure the User Repository in local_repo_config.yml

Add the user repository URL to the local_repo_config.yml file.

Step 6: Run Omnia Playbooks

Run the following playbooks in order:

  1. local_repo playbook

  2. build_image playbook

  3. provision playbook

The Vast client will be installed on the nodes successfully after the provision playbook completes.
