I checked in what I hope is the fix.  The cplist code needs to be cleaned up
as it is not clear which counts are counting bytes/store blocks/disk volume 
blocks.

WARNING: this fix required changing the disk structure which will result in a 
cache WIPE!

 Key: TS-773
 URL: https://issues.apache.org/jira/browse/TS-773
 Project: Traffic Server
  Issue Type: Bug
  Components: Cache
Affects Versions: 2.1.8
 Environment: Debian Lenny 5.0.8 2.6.34.7 x86_64
 12 1.5TB harddrives for cache disks. 
Reporter: David Robinson
Assignee: John Plevyak
 Fix For: 2.1.9


 Using 1.5TB harddrives as cache disks results in ATS only using 512GBs of the 
 disk. The disks are configured in RAW mode with no partition information.
 storage.config is setup like this,
 /dev/sda
 /dev/sdb
 /dev/sde
 /dev/sdf
 /dev/sdh
 /dev/sdi
 /dev/sdj
 /dev/sdk
 /dev/sdl
 /dev/sdm
 /dev/sdn
 /dev/sdo
 fdisk -l /dev/sdo
 Disk /dev/sdo: 1500.3 GB, 1500301910016 bytes
 255 heads, 63 sectors/track, 182401 cylinders
 Units = cylinders of 16065 * 512 = 8225280 bytes
 Disk identifier: 0x
 Partitioning a disk into 3 512G partition and adding then to storage.config 
 will make ATS use the entire 1.5TBs of space.

John: Do you foresee more fixes for this bug before v2.1.9, or does this 
complete this bug?

Unfortunately, the hosting code is pretty complicated and poorly written.
I have tried to patch it, but it really should have a more comprehensive
audit.  If this patch fixes the immediate problem (which it seems to have, but
I'd like independent confirmation) we can put off the audit till after 3.0.

So I don't foresee more changes if we get the fix verified but I wouldn't be
surprised if there was still a problem under some circumstances... until a full
audit.
