Installing Amahi with RAID 1 in 2HDD setup. See this other page for [[RAID5]].
Also see another users setup of [[#RAID 1 with 3 HDDs]].
If you perform either of these setups and have trouble with one of the members of the RAID1 array not joining on reboot, try this possible solution. [[#Losing drive on reboot]]
So, to set the scene. I'm pretty much totally new to Linux and I'm just an enthusiastic amateur when it comes to computers in general.
Please add any other comments/corrections/suggestions as you see fit, and thanks to the first user who started this section and inspired to me ccontribute as well.

If you perform either of the above setups and find that on reboot one member of the array is not present and the command "mdadm --detail /dev/md0" shows that the array is degraded, the following may help.
In a Fedora forum thread - http://www.fedoraforum.org/forum/showthread.php?t=255048 it was found that some makes of hard drives can cause this problem as they take a while to spin up so the system ignores one of them and carries on with the degraded array.
To fix this, apply the recommended lines to your /etc/rc.d/rc.local file. Make sure you backup the file before doing this just in case and do this all as root.
