--------------------------------

Just a newbie to the Kafka community, maybe this one is a toy that I can play with.

> There is no automated way in Kafka 0.8.1.1 to make a migration of log data if we want to reconfigure our cluster nodes to use several data directories where we have mounted new disks instead our original data directory.
> For example, say we have our brokers configured with:
>   log.dirs = /tmp/kafka-logs
> And we added 3 new disks and now we want our brokers to use them as log.dirs:
>   logs.dirs = /srv/data/1,/srv/data/2,/srv/data/3
> It would be great to have an automated way of doing such a migration, of course without losing current data in the cluster.
> It would be ideal to be able to do this migration without losing service.
