Remove disk

[Andres Gonzalez]

Hello,

I have a pool with 8 disks, 2 Z2 vdevs.
I had a problem with a disk but by mistake instead of replacing the disk I have added the new one to the pool and now I have 2 Z2 vdevs and a new with 1 disk (stripe) vdev.
I there anyway to remove/delete the stripe vdev from the pool and add it to the z2 degraded vdev ?

- SO: FreeNAS 9.10.2
- HW: FreeNAS Mini XL

Thanks.

If you remove the stripe vdev and select the option mark disk as new, you can then add it to the degraded pool by selecting the failed disk and then replace. Do it via the GUI so as not to hose anything.

I read this as there is no data on the dev correct??, Because this will destroy anything thats on the single disk.

I don't have the option to remove it, only to offline the disk.
But if I select it (offline), I get: Error: Disk offline failed: "cannot offline ada1: no valid replicas, "

I read this as there is no data on the dev correct??, Because this will destroy anything thats on the single disk.

It's correct, the single (Striped) disk has no data but it's part of the degraded pool now.

This looks strange, why some of your disks list as the dev ada instead of gptid. Looking at this is looks as though ada1 should have replaces the offline disk from raidz2-0?

idk, but agree that it's strange. Any idea if it can be fixed ?

Exactly, ada1 should replace:
