In this tutorial, I will go through the steps necessary to create a RAID volume in Raspbian OS on your Raspberry Pi. RAID allows redundant, quick or extended storage depending on which RAID level you go with. I’m going to assume that you’ve followed my previous tutorial on how to install and run Raspbian OS from a USB Flash Drive, although this isn’t necessary.
As we’re using a software RAID controller, we can’t run the OS from our RAID volume, but we can use to for storage. This tutorial is part one of two where we will use our RAID volume for creating our own cloud storage platform using OwnCloud. View the Installing OwnCloud on Raspberry Pi tutorial.
