### Basic Provisioning of Partitions and File Systems ###

  1. Ability to provision extra storage on-the-fly
Steps:
 1. Identify available storage
  a. 'fdisk -l' - returns connected storage
 2. Create partitions on desired hard drive:
  a. 'fdisk /dev/sdb' - interacts with /dev/sdb drive
  b. 'n' - to add a new partition
  c. 'p' - primary
  d. '1' - start cylinder
  e. '+4096M' - to indicate 4 Gigabytes
  f. 'w' - to write the changes to the disk
Note: use 'partprobe partition (/dev/sdb1)' to force a write to a hard drive's partition table on a running system
Note: 'fdisk' creates raw partitions
 3. Overlay (format) the raw partition with a file system
  a. mke2fs -j /dev/sdb1 - this will write inodes to partition
 4. Mount the file system in the Linux file system hierarchy:
  a. mkdir /home1 && mount /dev/sdb1 /home1
  b. mount OR df -h - either will reveal that /dev/sdb1 is mounted
Note: lost+found directory is created for each distinct file system
 5. Configure '/home1' to auto-mount when the system boots
  a. nano /etc/fstab and copy and modify the '/home' entry
