Running ZFS with 2 GB of RAM?

Deerslayer · 11-15-2013, 01:18 PM

I've been wanting to play with PC-BSD, but I'm not sure that I have enough RAM. I found a site that recommended 1 GB per TB of storage, so going by that, it sounds like 2GB would be enough, since I'm just using it to play with, on a small partition (20 - 40 GB). But I've also seen sites that recommend 8 GB for ZFS. Has anyone here run it with 2 GB (or less)?

I've used zfs on some pretty light systems. It will work fine for testing.

Hi, for me 2GB of ram isn't enough. If then you want play..
I think you need min 4GB.

You can try with only 2GB and do some tests. Let us know

I use ZFS pool (mirror) with 2TB of data on system that has 1 GB RAM, works good.

The minimum for ZFS I would say is 512 MB with ARC limited to 128 MB.

Of course its best to use as much memory as possible with ZFS, 4 GB is optimal minimum, but more then 256 GB RAM is still welcome
