> Handle disk failures gracefully

>                 Key: KAFKA-4124
>                 URL: https://issues.apache.org/jira/browse/KAFKA-4124
>             Project: Kafka
>          Issue Type: Improvement
>            Reporter: Gokul
>            Priority: Major
> Currently when a disk goes down, the broker also goes down with it. This 
> causes too much reshuffle of data over the network to replace the broker. 
> Make the broker resilient to disk failure. 
> The broker can detect a disk failure, mark it bad and then re-replicate the 
> under replicated data in all other available disks in the node. If the bad 
> disk is replaced with new one, the broker can rebalance the data among all 
> other disks it has. The broker can also tolerate upto n disk failures.
