Need to replace device

[DaffyDuke]

While I was trying to replace a failed device, I forced something I should not, but I thought warning message was just a confirmation needed, not a real message to not do what I was trying to .....

Now, I have a zpool with
3 devices in a raiz (and one failed, OFFLINE now)
1 device in a stripe (that should replace failed one).
NAME STATE READ WRITE CKSUM
freenas DEGRADED 0 0 0

And I can not replace hard drive now, here is some tries :

[root@freenas] /data# zpool remove freenas 14657110215957473015

What should I do ?

Ouch, sorry for my poor english and this bad copy / paste, I totally forgot something : "hello all, and thank you for your help".

There's nothing you can do to "fix" this. You need to destroy the pool and recreate it from scratch.

And always, always stick with the GUI and follow the manual's instructions closely. The situation is still recoverable, but using random ZFS commands might change that.

Don't use the CLI to replace a disk. The GUI has helpful little buttons you click and they do all the hard work for you.

OK, thank you all, I was in the same way ...
