I’m not sure what it is, but Scale has never thrilled me. I’ve tested it a couple times and I just didn’t get along well with it. I’ve tested know Jim Salter (practicalzfs.com) has frequently recommended XigmaNAS as a strong (albeit less pretty) alternative to TrueNAS. I did some tests with that as well and it seemed perfectly fine. In the end I decided that when I migrate off of Core this winter, it’ll be to a bare metal FreeBSD system. I’m using it as an excuse to better learn that ecosystem and to bone up on ansible, which I’m using to define all of my settings.
