Connected the second physical disk of exactly the same volume.

I want to merge disks like Stripped (similar to RAID0)
Tell me how to do it right?

Answer 1

Question removed. Through attach, a mirror is added
. It was necessary to add it like this:
zpool add data-zfs /dev/sdd

Answer 2

Add another disk to the pool. But I do not recommend doing this, because if at least one disk fails, then the entire pool and the data on it will become unavailable.
