root@itsme ~# fdisk /dev/sdc
Device contains neither a valid DOS partition table, nor Sun, SGI or OSF disklabel Building a new DOS disklabel. Changes will remain in memory only,until you decide to write them. After that, of course, the previous content won't be recoverable.
The number of cylinders for this disk is set to 7832. 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)

Syncing disks.
Next you use lvm in command line mode to create the Physical Volume (pv), create the Volume Group (vg), and last create the Logical Volume (lv). Everything in this example is done to the frist partition (sdc1) on the drive sdc.

Next edit fstab to mount the drive.

Next created the new root directory to mount the drive to.
root@itsme~# cd /

Next make the file system format.
