Am I building this RaidZ2 with different drives right?

[jbrown7815]

Gonna try and keep this simple. Setting up my first Pool. I have 6 total drives, (5x) 2tb Reds (1x) 3tb red...I just want the 3tb to work as a 2tb so I can have (6x) 2tb drives in RaidZ2.... 8tb useable, 4 in parity.


Do I have to partition the 3tb into a 2tb to make it all work?

What I tried to do was use manual setup under the volume manager, selected all the drives and select RaidZ2. Is this correct?

That is correct. No need to partition as your pool will be sized according to the smallest drive in the vdev.

So this looks right?


Assuming the 10.9TiB is my total storage not including parity, and with parity is the 2nd row? So 7.0TiB useable?

10.9TiB is your total pool size including your parity drives. The 7.0 is usable space. Just make sure you don't use more than 80% of your 7.0 TiB or performance will take a significant hit.

Got it, thanks. Now to create and delete all of this a few more times till I grasp it. CIFS shares permissions are messing me up, lol.

Not to jack his thread, but is this a ZFS rule of thumb? I am planning a build soon, and I haven't read this yet.

Yes. In fact, you get a WebGUI warning when you go over 80%.

Hmm. Interesting. Now I wonder if I need to go with 9x4tb instead of 8 :/
