I have 4 kafka brokers and 3 zookeepers deployed upon kubernetes. Out of 4 only 2 kafka brokers are working and rest 2 keep shutting down and restart with below error:

Exiting because log truncation is not allowed for partition byfn-sys-channel-0, current leader's latest offset 2 is less than replica's latest offset 21 (kafka.server.ReplicaFetcherThread)  

Below is the config of kafka

KAFKA_ZOOKEEPER_CONNECT zookeeper0:2181,zookeeper1:2181,zookeeper2:2181
KAFKA_UNCLEAN_LEADER_ELECTION_ENABLE    false

KAFKA_DEFAULT_REPLICATION_FACTOR    3
KAFKA_BROKER_ID 2

Please let me know how can i fix this ?
