I'm setting up a home-use FreeNAS - storage of photos, media, laptop backups and so forth for a pair of users and half a dozen laptops, phones, tablets. I have 4x 3TB drives. I'm deciding on the drive/zpool topology.
This blog post makes a (to me) set of convincing arguments for using mirror vdevs instead of raidz.
I believe I would like:
- 2 vdevs of 2 drives each
- drives mirrored in each vdev
- 1 zpool containing both vdevs
My question - how do I set that up within FreeNAS? Is it possible via the GUI (and if so, how?), or do I need to drop down to the shell?
1The missing part was that the GUI allows one to drag out a 2x2 grid of drives which is what I want - 2x mirrored vdevs each with 2x drives. It wasn't obvious to me. – Peter Mounce – 2016-12-06T10:17:11.667
