How to speed up raid1 resync ?



Just echo large numbers into both min and max resync speed proc entries:

/proc/sys/dev/raid/spped_limit_max and speed_limit_min

e.g. as root do:

 echo 200000 > /proc/sys/dev/raid/speed_limit_max
echo 200000 > /proc/sys/dev/raid/speed_limit_min

And watch the speed fly up till it maxes out your hardware. (-:

The above will set both speeds to 200MiB/s which ought to be more than

your devices can do...
