I'm setting up a FreeNAS server with the following 3 storage drives
- 2 80 GB drives
- 1 40 GB Drive
I choose ZFS with RAIDZ since it seemed like the only free RAID that supported multiple disks. However when I setup FreeNAS I was surprised that I only had 76 GB of usable space. Where did the other 124 GB go?
What am I missing here? Isn't ZFS supposed to allow you to use multi-size disks and still have redundancy? How can I configure FreeNAS (I would prefer to stay away from the command line, but will go there if its absolutely necessary) to give me the most storage with protection?
