Re: formatting a 12.73 Tb disk on ROCKS 5.2



I removed the one partition created by fdisk, because it was too small.

fdisk /dev/sda

WARNING: GPT (GUID Partition Table) detected on '/dev/sda'! The util fdisk
doesn't support GPT. Use GNU Parted.


The number of cylinders for this disk is set to 1702051.
There is nothing wrong with that, but this is larger than 1024,
and could in certain setups cause problems with:
1) software that runs at boot time (e.g., old versions of LILO)
2) booting and partitioning software from other OSs
   (e.g., DOS FDISK, OS/2 FDISK)

WARNING: The size of this disk is 14.0 TB (13999848554496 bytes).
DOS partition table format can not be used on drives for volumes
larger than 2.2 TB (2199023255040 bytes). Use parted(1) and GUID
partition table format (GPT).


Command (m for help): p

Disk /dev/sda: 13999.8 GB, 13999848554496 bytes
255 heads, 63 sectors/track, 1702051 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
