With 2.2 kernels, you can simply use 'cat /proc/sys/dev/md/speed-limit', to see the *minimum* rebuild rate. You can change it using something like: 'echo 200000 > /proc/sys/dev/md/speed-limit'. With 2.4 kernels, there are two files in '/proc/sys/dev/raid/', called 'speed_limit_max' and 'speed_limit_min'. I think the rest is pretty obvious. You don't have to destroy system performance... micah _______________________________________________ linux-lvm mailing list linux-lvm@sistina.com http://lists.sistina.com/mailman/listinfo/linux-lvm read the LVM HOW-TO at http://tldp.org/HOWTO/LVM-HOWTO/
