• One or more nodes, typically a wolf/boro node, provisioned with a supported OS snapshot

  Code Block
  [user@wolf-ssh-2 ~]$ nodemgr install --profile daos_ci-el8.35 --nodes=<node>

• Verify password-less ssh access between all nodes

  • Code Block
    ssh user@<node>

  • If passwordless ssh is working, you will not be prompted for your password. If you are prompted, please take a review your /wiki/spaces/DCO/pages/9497319397. If you still have an issue please submit a ticket to DCO.

• Enable sudo access for your account on each node

  • Log in to your node(s) as root

  • Code Block
    ssh root@<node>

    • You will be prompted for the root password. If you do not have this password, please contact your team lead to get it.

  • Create a sudoers file for your user:

    Code Block
    [root@<node> ~]# visudo /etc/sudoers.d/<username>

  • Include the following in this file (replace <username> w/ your username):

    Code Block
    <username> ALL=(ALL) NOPASSWD:ALL

  • Once this is finished, you should be able to ssh in as your user, then use sudo, or sudo -i for everything moving forward.

• Install avocado (LTS release >= 69) on the node from which you will be running the tests

  • RPM installation (RECOMMENDED; currently supported on CentOS 8; others coming soon)

    Code Block
    $ sudo dnf install python3-avocado{,-plugins-{output-html,varianter-yaml-to-mux}}

    Pip install

RPM Install Steps

1. Obtain DAOS RPMs - multiple options

   1. Build them from sources

   2. Download them from a PR or recent successful master PR

      1. E.g. https://build.hpdd.intel.com/job/daos-stack/job/daos/job/master/5259/artifact/artifacts/

         1. Replace “5259“ with your PR number

         2. Select the appropriate OS sub-directory

   3. Use the repositories in the snapshot image to find the RPM version

      Code Block
      $ sudo dnf list --showduplicates daos

2. Install DAOS RPMs on each node

   1. The following command will install the daos, daos-client, daos-server, and daos-tests RPMs on one host (similar to CI).

      Code Block
      $ sudo dnf install ~/rpm/daos{,-{client,server,tests}}-<version>.rpm

3. Optionally install other RPMs as needed for testing

   1. Latest master builds can be found at https://build.hpdd.intel.com/job/daos-stack/

      1. Example IOR: https://build.hpdd.intel.com/job/daos-stack/job/ior/job/master/lastSuccessfulBuild/artifact/artifacts/

   2. Can also use the repositories in the snapshot image

      Code Block
      $ sudo dnf list --showduplicates ior

Running functional tests with RPMs

1. Set python environment for avocado modules, e.g.,

   Code Block
   export PYTHONPATH=/usr/lib64/python3.6/site-packages/

   Note: /usr/ directory in the above path might be /usr/local, if the python modules were not installed by superuser.

2. Apply any python test code changes in the RPM install path (owned by root)

   Code Block
   sudo vi /usr/lib/daos/TESTING/ftest/<dir>/<file> sudo cp <modified_file> /usr/lib/daos/TESTING/ftest/<dir>

3. Run the test

   1. When running with unique server and client nodes

      Code Block
      cd /usr/lib/daos/TESTING/ftest ./launch.py -crispa -ts <server_nodes> -tc <client_nodes> <test_tag_or_file>

   2. When running with nodes that can perform any role

      Code Block
      cd /usr/lib/daos/TESTING/ftest ./launch.py -crispa -ts <all_nodes> <test_tag_or_file>

4. View results

   Code Block
   less ~/avocado/job-results/latest/job.log
