I had a mirrored zfs pool called "wd" with two disks: sda and sdb on a proxmox. To expand the disk, I detached sdb, added a new disk, sdc. Resilvered it and detached the remaining old disk sda. Unfortunately I messed up and now I would like to have my old two disks sda and sdb running again.

Since sdc is the only remaining disk, I cannot detach it. Is there a way to attach it as a master, so it won't be overwritten by the content of sdc? Or any other idea? I tried to cut sdc from power and try a import but this does not seems possible.
