解决方案

  1. Check broker logs for detailed stack trace: `grep -i 'UnknownServerException' /var/log/kafka/server.log`. Then run `fsck` on the data directory or replace the disk if bad sectors are detected.
  2. If corruption is isolated to a topic partition, use `kafka-reassign-partitions.sh` to move replicas to a healthy broker and delete the corrupt data directory.

无效尝试

常见但无效的做法:

  1. 80% 失败

    Restarting the broker without checking logs or disk health only delays the error; the underlying corruption persists and will recur.

  2. 90% 失败

    Increasing replication factor doesn't fix the corrupt data on the affected broker; it just adds replicas that may also encounter the issue.
