Mount block device

How to mount a new block device (CentOS)

# Check current status: shows no partition info and disk ID=0x0

sudo fdisk -l

Disk /dev/xvdc: 214.7 GB, 214748364800 bytes
255 heads, 63 sectors/track, 26108 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0x00000000

# Create a partition. Answer prompts as indicated
sudo fdisk /dev/xvdc
n # new partition
p # primary
1 # partition no.
<enter> # accept start cyclinder default
<enter> # accept end cyclinder default (take whole device!)
w # write partition

# Verify. fdisk should show new partition info
sudo fdisk -l
