Hello guys!
Short time lurker here, just recently became interested in building my own NAS and want to do it right so I've been scouring these forums like crazy lately. I've found lots of useful information and answers to most of my questions, but I still haven't found a definitive answer to how many hard drives is the minimum to start with.
My situation is this: I want to build a mini-ITX Pentium G3220-based NAS starting with as few drives as possible so that I can afford all the major equipment and add drives in the coming months.
I could set up 3 drives in a 2+1 RAIDZ-1 setup, but I'd be limited to only one parity drive and as far as I've read, it's impossible to upgrade a RAIDZ-1 zpool to a RAIDZ-2 with additional drives.
Would it be practical to start with 2+2 drives in RAIDZ-2, and add up to 2 more drives later on? Is adding drives this easy, or is an entire ZFS rebuild required?
