Ok, the vagueness was all mine then: it is the boot volume I'd like  
to make part of a RAID1.

Ok, then what's the deal with "the target disk has a single  
partition"? If it's interested in volumes only, not drives, it  
shouldn't need to care? Anyway, there is only a single partition, so  
I figure it _should_ work.

Well, I read the manpage but it didn't answer my question, neither  
did I find an article that does. Do you happen to have a link handy?
