Check /proc/mdstat to see how far along you are. When I was setting up an AS 2.1 machine, I had to increase the minimum speed: echo 80000 > /proc/sys/dev/raid/speed_limit_min That made the RAID rebuild go significantly faster. I think that I found a bugzilla report about it, but I don't see it now. If that works for you, you may want to file a bug report to increase the minimum speed to something more sane. I don't think that I actually got 80M/s, but it was significantly faster than the 1M/s original rate. Forrest
