Enlarging Pool v24.10

I have a Z2 pool 6 discs wide. I want to add a seventh. I use the add to pool button. I select the pool. I click through everything else and when I get to the end it errors saying no vdev was assigned. But I saw no way to do that in the wizard. And isn’t the vdev in question already established in the original pool? Why am I adding another?

BTW, it does see the seventh drive. All the drives are the same size.

What did I miss? No online videos are up to date.

Thanks.

Yeah, reading is hard.

Extending the vdev is what you need to do.
