Rob - can you add space for WSC-reach if you haven't already? As noted in email, if we're short, deallocating IRBO for now would be OK (or other option - you know more about what the best options are). Give me a call if you think there's no good option and let me know if you have to scavenge from IRBO / elsewhere in a way that means we need to buy more disk or get Lustre up again, etc.
