Hi, I have a general question on operating software RAIDs in linux. I am running md RAID in linux 2.6.12 kernel. I observed that the sync speeds were always much closer to /proc/sys/dev/raid/speed_limit_min value, than /proc/sys/dev/raid/speed_limit_max value. I agree that disk activity (I/O) and other system usage will bring down sync speeds. But I want sync speeds to be higher at whatever cost. So I thought I will just set max value to around 500000 and leave the min at 5000. But with idle disk activity and otherwise idle system usage, I still see sync speeds around 5300Kb/s only.
So Is the 2.6 kernel designed to sync at speeds closer to min than max?
Please advise.
