linux - FIO verify_state_load 和触发器不起作用

Question

我正在尝试使用 fio 在关机后验证存储中的数据， 为此目的，使用 fio 写入 --trigger-file 选项以在中途停止 fio 操作(并模拟断电)。
然后使用--verify_state_load选项读取fio，只检查成功完成的部分数据，但是验证失败，似乎state_load没有效果(读取验证将正常工作如果写入作业未被触发器部分终止，则符合预期。

使用trigger/state_load有什么限制需要注意吗？

Answer 1

我的问题似乎是因为我使用 fio rw=randwrite 生成数据并分离 rw=read 作业以在触发后验证数据，使用 rw=randread 验证数据解决了我遇到的问题
