--------------------------------
Just a newbie to the Kafka community, maybe this one is a toy that I can play
with.
> automatic migration of log dirs to new locations
> ------------------------------------------------
>
> Key: KAFKA-1689
> URL: https://issues.apache.org/jira/browse/KAFKA-1689
> Project: Kafka
> Issue Type: New Feature
> Components: config, core
> Affects Versions: 0.8.1.1
> Reporter: Javier Alba
> Priority: Minor
> Labels: newbie++
>
> 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.
