Part 2

Add 3 new 50 MB Fixed Size Virtual Disks to your linux Partition. This is done using the Virtual Box interface while your Linux Virtual Machine is shut down.

Switch to the root user

sudo su -

Using fdisk create 3 new linux raid auto partitions. One for each new drive added. Use the full space available on each disk.

i.e. /dev/sdb1 /dev/sdc1 /dev/sdd1

install mdadm package

apt-get install mdadm

*If asked for a mail server choose No Configuration

**This can take a few minutes to install.

Create a striped array (RAID 0) using all three disks.

Create Filesystem on New Raid 0 Array

Mount your new striped filesystem

What is the size of the filesystem? Why?

Repeat Part 1 of this assignment but this time make sure you are using your new striped filesystem. To do that just change to that directory

cd /stripefs

Summarize your findings about your new RAID 0 filesystem and iostat output.

Did you achieve desired results? If not, why not and what would need to be changed in a real world production server to achieve desired results
