mdadm: throttling the resync activity

25 March 2015

If a raid is rebuilding disk access is mostly very slow. Sometimes it’s better to slow down the rebuild-process for a while. This can easily done by:

echo 100 > /proc/sys/dev/raid/speed_limit_max

Default value for speed_limit_max is on my system 200000
