Has anybody EVER successfully recovered VINUM?

If this is indeed true, which I find a bit hard to believe, it should be 
fixed ASAP.  I've never seen a RAID that had to be taken _offline_ to 
rebuild parity onto a failed and replaced drive.  I've triggered 
rebuilds on a few so far, including h/w RAID, RAIDFrame and the Linux 
raid* thing, and it has always worked nicely while there was heavy load 
on the volume (with reduced performance during the rebuild, of course.)
