Have I created a new pool?

[Krist8]

I read the manual to extend the volume (I guess I did not read and understand properly) using a new WD Red 3 TB. I already have a pool (NAS) which has a WD Red 3TB (with 2 partitions). So, I clicked the extend volume (thinking that it will give me a choice of mirror, stripe, etc.), but it just went ahead and added my new HDD. Here is what I got from zpool status:

Code:

[root@freenas ~]# zpool status												 
  pool: NAS

So do I have 2 pools or is it a stripe pool? How do I go about detaching or delete the 2nd pool?

You have a striped pool of 2 drives. You don't remove it, the only way to undo what you did is to destroy the pool and start over.

Thanks. I am starting new. I only use FreeNAS as a backup for my 2 desktops and 2 laptops. So, I do not think I need a mirror. Stripe is too risky. So how do I install the 2 HDD’s? Do I have to create 2 pools and assign one drive to each pool?

Some uses of external storage don't require redundancy. It's just that one of the key features of FreeNAS is reliability due to redundancy. You have to decide.

Yes, create 2 pools. And create at least one share on each pool so clients can access them..

There is no choice if you're only extending with one disk. If you're adding multiple disks, you can choose how those disks will be arranged.
