| ERROR: User Data found on node. Node not clean: Found user data on the node. ['/primary/w16z', '/primary/w24z', '/primary/w8z', '/primary/w4z', '/primary/w12z', '/primary/w20z'] The node is not clean and not ready to be added. | ||
| Cause: | This error occurs when a previous aster installation is uninstalled, but the w*z directories were not removed. | |
