Maybe it was all the stuff about this being the 25th anniversary of Linux and all, I felt the need to redo my desktop. Initially it was Kubuntu Xenial on the cheapy 240gb SSD.. then I realized how many 1TB drives I had sitting around. I tore it down and rebuilt it using these fantastic instructions on how to install Ubuntu root on ZFS.

This is running in a desktop with a 4690k with 20gb of RAM. I’m very curious to see what effect, over time, that cache device will have on responsiveness.
Through the course of setting this up, one of my 1TB drives failed, and I was able to replace it no problem. I just needed to remember to run ‘grub-install’ on the new drive.
Hope everyone is having good luck with their projects!
