NSURL getResourceValue: for NSURLVolumeMaximumFileSizeKey returns nil

Hello,
Can anyone tell me why calling NSURL -getResourceValue:forKey:error: with key NSURLVolumeMaximumFileSizeKey would return a nil resource value for a given volume? The function returns YES and error is nil also.
I can see from running dtruss that it in turn calls getattrlist(). If I call getattrlist() myself on the same volume, I can see the bits I would think it is looking at are set correctly - VOL_CAP_FMT_2TB_FILESIZE. 

Thanks,
Scott
