Hi Phil!
followed you order. removed the disks, deleted the disks and the pool, rebooted, everiting was removed, insert the disks again, set a redirect role on the partition of the …VN0033 disk and imported the pool. But it doesnt resulted in what we should expect.
The pool was successfully added, but after a reboot the disk i added was again gone from the pool as before The “older” disks are still there!
Now it looks like this:
There must be a bug somewhere! I tried it several times…alwasy the same result.
