Yeah, its an actual special vdev I added to speed up metadata and small
file access. zpool-detach I think only works on mirrors and not raidz
vdevs. From searching google, there does not seem to be a way to detach
a special vdev from a raidz pool.

Oh I didn't realize those disks were part of the larger pool, I thought
they were a separate pool named “special”. You might be able to simply
detach and then re-attach both drives, afaik a draid can function
without its special vdev.
