New NAS (Recommendations)

[michael230]

Hey guys is it normal to get da0s1: geometry does not match label (16h,63s != 255h,63s). on FreeNAS-8.2.0-RELEASE-p1-x64 (r11950)?

Everything boots fine and no alerts on the GUI.

Seems it's "normal" to get this warning when booting from flash drives.

Thanks Stephens for the reply, I was wondering did I make a mistake creating only 1 vdev to my zpool? The reason I asked this is that if my vdev fails then I will not be able to recover. I do have 2 Controller cards and if one of my controller fails is it possible that it will impact my vdev integrity? also what are the chances of my vdev failing ?

If any vdev fails, you lose everything in the zpool. Read the guide in my signature.

With raidz2 I wouldn't go with any more than 10 disks. Best practices are to keep vdevs under 9 disks. Given that you have 12, I suggest you destroy the pool and create a new pool consisting of 2 x raidz2 vdevs of 6 x disks each.

Hi Noobsauce, I read your documentation and this is why I made the previous comment and BTW thanks again for writting it.

Below is my config:
Motherboard -> 4 Drives x 2TB
Controller 1 -> 4 Drives x 2TB
Controller 2 -> 4 Drives x 2TB


I wanted to have at least 16TB of usable data and wondering if I should go and create (1 VDEV x 6) x 2 to 1 ZPOOL but as per your document if any vdev fails you loose your data. This means I would need to have 24 drives to be completely safe or is there any way to repair the vdev.


This is how I was thinking of configuring the system

6 ---> VDEV 1 ---> ZPOOL1
6 ---> VDEV 2 ---> ZPOOL1

Questions:
1. Now should I take under consideration the Controller's example add VDEV for Controller 1 (4 HD's) + 2 HD's from Motherboard and VDEV2 for Controller 2 (4 HD's) + 2 HD's From Motherboard or does it really matter?

2. Will the ZPOOL1 be transparent meaning it's 1 huge (Volume of usable data) or will it be split into 2?

3. Also what are the chances of a vdev failing or a better question is how can I avert my vdev failing?

4. Will this new setup be able to repair each others vdev or am I out of luck on recovering the data from that vdev?


Another question... Should I just upgrade my FreeNAS to 8.3.0 and add the new zfs revision?

Sorry that I'm asking so many questions as I just want to ensure that I have the appropriate setup before reconstructing my zpool again and because it's such a huge amount of data I want to ensure I have a permanent solution for my Data storage.

Thanks again guys and I'm really sorry about all these questions.
