Your problem was running it on a distro the didn't support it. (As you acknowledge.)

So far it's been running absolutely great for me on several Ubuntu installs.

Indeed. Arch is good for a few things, but sometimes stability isn't one of them when it comes to unsupported packages. ;)

I'm not sure I'd be brave enough to run ZoL again, but given Ubuntu's FAR wider install base and availability of binary packages, it's the better option if you have to choose.

My personal preference would be to stick with ZFS on FreeBSD. Performance is probably better.
