linux

                 Key: TS-1163
                 URL: https://issues.apache.org/jira/browse/TS-1163
             Project: Traffic Server
          Issue Type: Bug
          Components: Cache
            Reporter: B Wyatt
            Assignee: B Wyatt


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.
