Adding disks to a raid10

[andrema2]

Hi

I have a raid10 as 2x6tb, 2x2tb and 2x4tb. One disk of 2 TB is failing. I have bought 2 4tb disks. My idea is to replace the 2x2tb set by the new ones.
So far, I’m unable to find a way to do it thorough the GUI.
It’s just change the first disk that is failing for one of the 4tb and once it’s finished recovering I change the second one and expand the pool ?
Or it has to be done via CLI only ?

How can I accomplish it ?

I’m running 12 U1.
Thanks

It's documented in the manual

replace the failed disk first, wait for it to remirror, then replace the other one and it will automatically expand.

Tks. I followed the instructions on the manual and it was perfect.
I should have look it before asking. Sorry for that
