+## Fixing Broken GlusterFS Repo
+If you experience the following [issue](https://github.com/mrlesmithjr/ansible-rpi-k8s-cluster/issues/7) you can
+run the playbook [fix_glusterfs_repo.yml](playbooks/fix_glusterfs_repo.yml) which
+will remove the broken `3.10` repo. Once that is done you should be good to go
+and be able to run [deploy.yml](playbooks/deploy.yml) once again.
