It's worth taking a look at the trend in space utilization though, because it's entirely possible that at their current rate they may need to buy a new shelf X months down the road anyway, and if so it may be more cost-effective to just buy it now and save the headache and downtime involved with shrinking the existing volume.
I find with our filers that I can pretty much plot out on a graph when a new shelf is needed, and it's usually less than a year.
Of course, the moral of this story is: Be careful when you add disks to volumes.

Indeed... recovery could be costly and/or awkward. Perhaps Netapp would consider a "safety feature" enhancement for "vol add/create" command where by default it will not allow a situation in which a volume/raidgroup is left with no hot spares. Add a "-f" switch (or whatever) to force an override. Warm fuzzy feature. :)

This is a great idea. And should be only a couple line of intern-level code to implement too.
