Hi, I have a 3 node cluster with kafka version 0.9.0.1 with many topics having replication factor 3 and isr 2. Node 0 is running multiple mirrormakers.
Node 1 in this cluster has an issue and lost all data from disk (All kafka data logs got deleted from disk). Kafka broker is down but zookeeper is still running and its data folder is available on this node. Node 0 and 2 are still alive and processing data. -Any inputs or suggestions on the best way to restore Node B and replicate say 20TB of data from Node 0 and 2 ? -Will just restarting the Kafka server replicate data to this node from Node 0 and 2 ? (This seemed to work for a small volume of data, but wondering if this is the right approach to take for larger volume of data) -What are the best practices in terms of configuration parameters for broker and mirrormaker that need to be verified in this scenario ? Thanks, Meghana
