'dmesg' should show the log of what happened. One thing I've
seen is that a rebuild won't complete if you get an error
even on an unused spot on another part of the array. I'd
guess that's what happened. If your drives are smart-aware
try 'smartctl -a' to see if they have had errors. If not,
a crude test is to run 'cat /dev/sdn' >/dev/null and
run dmesg after it completes.
