Re: In a pickle got out of most of it.

I found out that the spare disk replaces the old disk transparantly,
after it syncs.  However, I also found out that one of my harddrives
had bad sectors! ( :( :( ).  And it wasn't the spare disk either.  So
I had to not sync (because trying to read the bad sectors would cause
that device to fail, bringing the whole array down).

Instead I just mounted ro, and copied the most important bits out
(well the ones that would fit on my sytem drive), then ran a badblock
program that I got from the manufacturer's site to "remove" the
badblocks (that is, hide them).  And finally rebuilt the array from
scratch.

The only lucky thing was that I still had the old array available,
just not onsite.  So after procuring it and copying it back onto the
new array (along with the saved bits) I've lost only about 10% of my
data.
