This post was suppose to be a “look I made an SSD ZFS pool”, but will instead be the first post in a trouble-shooting series. Trying to get my SSDs to behave.

But — I am getting ahead of myself… Let’s start at the beginning.

I recently had a couple of 2 TB drives to spare, and thought I would put them to good use as a ZFS mirror on my Arch Linux desktop.

My file server, Zeta, has an mdadm RAID6 array with eight 4 TB disks. I want to expand, but before doing so I’m going to migrate to ZFS.
