Description

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: 0x00000000

Partitioning a disk into 3 512G partition and adding then to storage.config will make ATS use the entire 1.5TBs of space.
