This email is an attempt to get some knowledge on how softraid works.
So many of your questions are answered if you start with bioctl(8)[1],
and continue with softraid(4)[2]. Maybe bio(4)[3] helps, too.
What's there is usually documented. What's not documented is usually
not
there. Or was it the other way around? ;-)

Happy reading, Marcus
Marcus, I read the docs carefully, and based on them, my best
understanding is still unclear on all 4 points -
* Scrub - MAYBE??? There's some words about "patrol" in the man page
that could mean it's there.
* Rebuild - I think I saw some console dump of the status of a rebuild
process on the net, so MAYBE or NO..?
* Hotspare - MAYBE, "man softraid" says "Currently there is no
automated mechanism to recover from failed disks.", but that is not so
specific wording, and I think I read a hint somewhere that there is
hotspare functionality.
* Hotswap - MAYBE, this would depend on if there's rebuild. Only
disconnect ("bioctl -O" I think; "bioctl -d" is to.. unmount or
self-destruct a softraid?)
The man pages are sometimes over-minimalistic with respect to an
individual user who's trying to learn, this is why I'm asking for your
clarification.
So your clarifications would still be much appreciated.
