Bought some cheap SSDs and just grabbed systems and platters I had around for it. Testbedding and getting some experience with the self hosted engine, since I’d like to move to it once it’s released. Also looking forward to testing native gluster on this setup.

Sounds odd, I know, but couldn’t get good support for a community nextenta server I inherited. I was having driver level box lockup issues with openSolaris that I couldn’t resolve. So I rebuilt it with linux, imported the pool, and haven’t looked back or had a storage failure since.

Funny, I used to be a Slacker as well, before I met BSD:) The leap is
actually quite small, which probably isn´t that surprising since Slack
is (or at least was, last time I worked with it) supposed to be the
closest to Unix you get, while running Linux:)
