You forgot to include the subject.

To get rid of the ghosts of wedges, there is dkctl delwedge (see man dkctl).

I have never used raid, don't know if the ghosts would come back after the next reboot.

It might be easier with Linux, FreeBSD or Haiku, where device nodes are dynamic, not preconfigured as in NetBSD and OpenBSD.

I don't know how OpenBSD denotes gpt partitions (device node).
