That's reassuring to know.

Just how bad is it?

Re-booting our file server is something I like to avoid.

Depending on how poorly, I could probably live with it (the RAID in question 
is the small system one, not the large user data one).

Hm, I guess I would need to re-boot and intervene manually in that case.
Just using the slow copyback looks preferrable if it doesn't take more than 
a day.

Probably I need to test this on another machine before.
I guess there's no way to initiate a reconstruction to a spare and failing 
the specified component only /after/ the reconstruction has completed, 
not before?
