Watson uses NFS for data storage and sharing, so you'd only need to toast the array on the NFS host. But, (assuming for fun that you could drop down to a root prompt) the linguistics programs probably don't run on the NFS host, so dd would be less effective. In that case, a recursive rm may be the right choice, but you have to find the mount point.
New thought: (further assuming for fun that you could drop down to a root prompt) just 'umount -a' to unmount all non-root filesystems, which includes the NFS mounts, and then it would have no data, and the algorithms would throw all kinds of 'file not found' errors.
By the way: they'd just reboot Watson. It crashed a bunch of times in filming, making each episode take nearly four hours each to film.
