解决方案

  1. Identify the offline directory from broker logs: `grep 'offline' /var/log/kafka/server.log`. Then unmount and check the disk with `fsck`, or replace it. After repair, restart the broker. Example: `sudo umount /data/kafka && sudo fsck -y /dev/sdb1 && sudo mount /data/kafka && kafka-server-start.sh config/server.properties`.

无效尝试

常见但无效的做法:

  1. 90% 失败

    Simply restarting the broker without addressing the disk failure will cause the same error; the broker will detect the offline directory again.

  2. 95% 失败

    Increasing log retention or cleanup policies doesn't fix a hardware failure; the underlying disk must be repaired or replaced.
