== Configuring Installing Ubuntu aka Trying RAID 10 on Web Server (2/15/2016) ==
Some general configuration options:
* don't encrypt home directory
* hostname: McNairWebServ
* user full name: McNair Center
* username: mcnair
* software: LAMP stack
* no automatic updates
Sahil and I tried to configure RAID 10 using the software RAID option in the installer, which is documented [https://help.ubuntu.com/community/Installation/SoftwareRAID#Partitioning_the_disk here]. We put two 64 GB swap space partitions on the first two hard drives, and created two ext4 partitions that took up the rest of the space on those two drives. For the other two drives, we used a single ext4 partition for each drive. For all of the ext4 partitions, we set the bootable flag to "on." Then we chose to configure the software RAID, created a new MD device, and chose RAID10 with 2 active devices and 2 spare devices. For the active devices, we chose the two ext4 partitions on the first two hard drives, and for the spare devices, we chose the two ext4 partitions on the other two hard drives. But then the installation process fails when the GRUB boot loader can't be installed, because the GUID partition tables (GPT) need a designated, small (1 MB is enough) partition for the GRUB bootloader.
Third RAID device (/dev/md2): RAID0, 2 active devices (/dev/sda2 and /dev/sdb2). set partition: use as swap area
'''Fifth partitioning attempt (make made sure all software RAID devices are removed, delete all partitions, create new partition tables):'''
First hard disk (/dev/sda):
