 I'm 99% sure it does because I could construct the RAID previously when
 RAIDframe read from "wd2" and wrote to "wd3" previously. The problems
 started when it had to rewrite parity the other way around (with
 "wd3" as the source).

 Is the above good enough? I would really like to avoid rebooting that
 machine again as it is my server.
 
        Kind regards
