I’m running Scale. I’ve found instructions for Core and many posts on the topic but I can’t seem to find anything up to date.
In Storage, there is an Add To Pool button which allows to add a drive to an Existing Pool. Is this the way? I want to move this 2-way mirror to a 3-way mirror.
You want to extend the vdev. if you add a drive you have a mirror+ a single drive.
It’s under storage → view vdev → then there will be two buttons extend and remove
