Render Farm ​

This page contains instructions on how to update the Flamenco render farm deployed at the Blender Studio. Most if not all studio computers will run Gentoo. The "Non Gentoo" computer section is for computers not managed directly by the studio.

Note

This assumes that you are on the same local network as the other computers on the render farm.

Non Gentoo workstation computers ​

To update Flamenco, you will need to run the deploy.sh on the Flamenco Manager. This will update the manager, worker, and add-on on the non Gentoo computers. After the deploy.sh has finished, you need to restart the workers from the manager webUI.

Extra credentials needed

Note to complete the following steps you need the correct SSH key to access the Flamenco Manager. Contact your Flamenco administrator to retrieve the SSH key.

Workers ​

  1. Run the deploy.sh script from the Flamenco git repo on the Flamenco Manager
  2. Go to the manager webui
  3. Select the workers you want to restart.
  4. Choose one of the "Restart" options in the menu, and press Apply.
  5. The workers are configured to automatically start again after they've been shut down from the web interface.

How to restart the worker without the manager

  1. ssh into the computer that is having issues restarting the worker
  2. Run the following command: sudo systemctl restart flamenco-worker
  3. Keep an eye on the Flamenco Manager web interface. It should show the worker is offline, and then it should become available again.

Add-on ​

The Blender add-on also needs to be reloaded, make sure that Blender is restarted on the affected computers.

Gentoo workstations ​

This section will only provide a quick rundown of how to update the Flamenco package that is part of the Render Farm setup.

For more details and how to update other packages, see the Maintenance page.

Note

The Flamenco package should already have the correct USE flags configured. However if you want to inspect what USE flags the current install has, you can use eix flamenco. This should tell you if the manager, worker, and/or add-on is included in the package deployment.

How to update the Flamenco package ​

To update the workers on the workstations, you need to:

  1. SSH to the build server ssh user@build-server-addr
  2. Use su to login as root directly
  3. Run emerge --oneshot flamenco to update the Flamenco worker/add-on
  4. Run date -R > /var/cache/update_info/timestamp.chk to signal to all workstations that there are updates available

Workers ​

You need to manually restart the workers from the webui after the Flamenco package has been updated

  1. Go to the manager webui
  2. Select the workers you want to restart.
  3. Choose one of the "Restart" options in the menu, and press Apply.
  4. The workers are configured to automatically start again after they've been shut down from the web interface.

How to restart the worker without the manager

  1. ssh into the computer that is having issues restarting the worker and become root
  2. Run the following command: rc-service flamenco-worker -s restart
  3. Keep an eye on the Flamenco Manager web interface. It should show the worker is offline, and then it should become available again.

Manager ​

If any of the Gentoo computers is running the manager, it can be restarted on that computer with:

rc-service flamenco-manager -s restart

Note that the manager is not deployed by default. It is only deployed if manager USE flag has been turned on.

Add-on ​

The Blender add-on also needs to be reloaded, make sure that Blender is restarted on the affected computers.
