Troubleshooting Tip: How to resolve 'Unknown Error -1' errors while adding a worker from the GUI

While adding a Worker from the GUI under Admin -> License -> Nodes, the following errors appear in the GUI.

Unknown Error -1

The script /opt/phoenix/deployment/jumpbox/datastore.py attempts to mount the NFS storage on the worker while trying to add it from the GUI.

To resolve this, follow the steps below.

• Check if /data and /archive storage are already mounted on the worker using the command below.

df -h

• If /data and /archive storage are already mounted, unmount them using the command below.

umount /data
umount /archive

• Here '-f' flag can be used if storage cannot be unmounted using the above command.
• Make sure that /etc/fstab does not contain any existing entries for /data and /archive, and remove any existing entries if added.
• Try adding the worker again, and it should be successfully added in the GUI.
