My problem is that my RAID unit (under configuration -> volume manager) It only
shows 16.7 TB. I have purchased an upgrade to 32TB max to
get the extra 2TB above the 16TB from the default license.
When I insert a Debian, Fedora or any other Linux cd, the installation
just shows 18TB / 18.000GB of storage.
How do I get the full disk capacity?
Everything seems to be ok. It is not an issue. Hard disk manufacturers count disk space in this way: 1 kilobyte equals 1000 bytes, but in fact 1 kilobyte equals 1024
bytes (binary).
Therefore in your case there are 18000000000000 bytes = 17578125000 kilobytes =
17166137,69 megabytes = 16763,80 gigabytes = 16.3 TB
Moreover fdisk shows capacity in the way disk manufacturers show:
fdisk -l
Disk /dev/sdb: 17999.9 GB, 17999994028032 bytes
255 heads, 63 sectors/track, 2188374 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
