> Due to 32bit integers in both the trafficersever code and the ioctl used to determine raw disk size, the number of sectors reported to the cache storage system is bound to 0-0xFFFFFFFF.  If a disk has 512 byte sectors and is larger than 2TB it will report (num_sectors % 0xFFFFFFFF) *  512 bytes avaliable.
