Home on the RAID
Last month we ran a simple tutorial on creating your own NAS, and in this issue we’re diving in deep with a full build, because we know how popular NAS devices are and this is a project we really want to get stuck into. Off-the-shelf NAS units are easy to come by, but they’re often underpowered, overpriced, or otherwise disappointing. Many of them run some kind of Linux (usually on quite modestly powered ARM hardware), and it’s pretty straightforward to build a Linux box, and cram it with as many hard drives as geometry permits. You may even have enough spare parts lying around to get most of the way there (we did). You don’t need anything special hardware-wise (4GB of RAM and a CPU sometime from the last decade is fine), but several large hard drives help. Many consumer-level NAS devices come in attractive small form factors, and thanks to their low power consumption, don’t require noisy cooling. So, we thought we’d try our hand at mimicking this.
If the prospect of using Linux makes you cringe, don’t worry – we’re going to use the fantastic OpenMediaVault, which (all going to plan) means you won’t have to touch a command line, and everything can be controlled from a friendly web interface. Next-gen filesystems, RAID, and LVM.
