Uninstalling Workbench

Before using the following instructions to uninstall Data Science & AI Workbench, be sure to follow the steps to backup your current installation so you’ll be able to restore your data from the backup after installing Workbench 5.2.

To uninstall Workbench on a healthy cluster worker node, run:

sudo gravity leave
sudo killall gravity
sudo killall planet

To uninstall Workbench on a healthy cluster master node, run:

sudo gravity system uninstall
sudo killall gravity
sudo killall planet
sudo rm -rf /var/lib/gravity /opt/anaconda

To uninstall a failed or faulty cluster node, run:

sudo gravity remove --force

To remove an offline node that cannot be reached from the cluster, run:

sudo gravity remove <node>

Where <node> specifies the node to be removed. This value can be the node’s assigned hostname, its IP address (the one that was used as an “advertise address” or “peer address” during install), or its Kubernetes name (which you can obtain by running kubectl get nodes).
