How to Setup Software RAID for a Simple File Server on Ubuntu

Do you need a file server on the cheap that is easy to setup, “rock solid” reliable with Email Alerting? will show you how to use Ubuntu, software RAID and SaMBa to accomplish just that.

Overview
Despite the recent buzz to move everything to the “all mighty”cloud,  sometimes you may not want your information in someone else’s server or it just maybe unfeasible to download the volumes of data that you require from the internet every time (for example image deployment). So before you clear out a place in your budget for a storage solution, consider a configuration that is licensing free with Linux.
With that said, going cheap/free does not mean “throwing caution to the wind”, and to that end, we will note points to be aware of, configurations that should be set in place in addition to using software RAID, to achieve the maximum price to reliability ratio.

About software RAID
As the name implies, this is a RAID (Redundant Array of Inexpensive Disks) setup that is done completely in software instead of using a dedicated hardware card. The main advantage of such a thing is cost, as this dedicated card is an added premium to the base configuration of the system. The main disadvantages are basically performance and some reliability as such a card usually comes with it’s own RAM+CPU to perform the calculations required for the redundancy math, data caching for increased performance, and the optional backup battery that keeps unwritten operations in the cache until power has been restored in case of a power out.
