Comment 1 Ashish Pandey 2017-06-12 11:25:17 UTC 
Description of problem: 

We should have a way to control self-heal for a disperse volume. At sometime when we have multiple bricks on a node. If a node goes down and comes up, several brick will start healing. This can lead to very high CPU usage and this can hamper ongoing IO. So we should have a mechanism to control heal, this will help in performing lazy heal during peak time and aggressive heal during less load.

We have come up with a script to control the CPU usage by heal.
That will solve the issue.
