Shamelessly inspired by this brilliant series of blog posts – http://breden.org.uk/2008/03/02/a-home-fileserver-using-zfs/ and http://pthree.org/2012/04/17/install-zfs-on-debian-gnulinux/ – both of which contain a great many more details than I will likely cover.
Before moving up to Newcastle, I picked myself up a QNAP TS-219P with a couple of 2TB drives mirrored. At the time, I ummed and ahhed about paying a bit more for a four disk version from an expansion perspective, but couldn’t justify it for a few reasons:
- Extra cost – I didn’t have any present *need* for the extra capacity, and there was a reasonable step-up in price for a single-function box I didn’t need the full capabilities of.
- Format – I knew if I was going to get a 4-disk-or-bigger version I would – longer term – want something rack-mountable, but at the time I had no rack to put it in. Without that, a rack-mountable NAS would just be silly.
Now, two years on, a few things have happened. Firstly, I’ve moved into my own place, complete with Cat6 wiring to as many places as I felt it practical and a rack to boot. Secondly – and perhaps more importantly in the context of these posts – I’ve reached the limits of my QNAP 2-disk solution. With an increasing multimedia collection, a refuelled desire to start taking more pictures again, and additional space for making a concerted effort to centralize my other data, more space is going to be needed.
However, as the next few posts should reflect, there’s a few other things I want the system to do, so the considerations (and cost) expand a bit beyond the remit of “NAS”.
