> Key: KAFKA-4096
> URL: https://issues.apache.org/jira/browse/KAFKA-4096
> Project: Kafka
> Issue Type: Bug
> Affects Versions: 0.8.2.0
> Environment: RHEL 7.2, AWS EC2 compute instance
> Reporter: Karthik Reddy
> Assignee: Neha Narkhede
> Priority: Critical
>
> Hi Team,
> We are trying to move the data on Kafka Cluster from one region to another
> region.Region here could be a separate Data center or a separate cluster
> within the same region.
> In the effort to do this, we have stopped the ZK/Kafka of the old Cluster,
> detached the EBS volumes where kafka stores all topics related data and then
> attached the EBS volumes to the new cluster.
> We observed that new ZK cluster came with all the data that previous ZK
> persisted meaning all the topic metadata and consumer offset information.
> However, on the Kafka side, we noticed that messages are not seen, all the
> index and log files are of empty size.
> The recovery point and recovery offset checkpoint indicate the correct base
> offset as present in the old cluster.
> Apart from the MirrorMaker strategy to move the data from all the topics, can
> you let us know is there any specific process to copy the file system
> snapshots from one region to other.
> We did restart of Kafka/ZK but that didn't help.
> Thanks,
> Karthik
