I'm looking into running a ZFS NAS and because it's the first time for me, I'm reading up a lot on how everything works.
Initially I thought RAIDZ1/2/3 would do something magically but still let me use all the capacity of the drives.
Already wondered how the hell this would work, and indeed it does not.
Last night I used five 1TB drives and placed them in a RAIDZ3, and I was left with 1.74TB usable space.
So that got me thinking. For a simple home NAS where I store my Blu-ray remuxes and AIFF music and some data I don't need high speeds. 1Gbit/s is enough, more is nice when I will upgrade my desktop to 10Gbit/s.
Safety wise it's obviously a personal preference. Do I allow one disk to fail, to be replaced and wait for the rebuild, or do I want to be able to be extra safe and use two or even three disks for that.
I'm not even talking about ZIL and L2ARC yet. Not even sure yet if I will. If I have a SSD laying around I might as well.
My server has a modified H310 for the storage, and a H710 for the RAID1 SSD boot disk, and I can add extra SSDs for other stuff like ZIL/L2ARC.
I would add at least six disks of 8TB, of which one will be for parity. I could possibly add two more disks for that. My Dell T320 has eight slots for disks.
For now I'm just wondering what other people with home setups have done or are doing.
What risks are you willing to take.
Everything is welcome.
