Well, let's say that would be optimal, but even
off-line could be OK.
BTW, what does it mean "off-line"?
Does it mean that /dev/mdX exists, but it is not
used (un-mounted), or it is just read-only, or
it should *not* exists and only the componing
HDDs are available?

Oh, thanks, I will consider the option.
