红帽全球峰会16.10. RAID 服务
以下组件协同工作，通过使用 mdadm 与 systemd 在系统中执行自动 RAID 一致性检查：
config.file-
/etc/sysconfig/raid-check文件包含 RAID 检查行为的配置说明。 raid-check.timer-
这是一个 systemd 计时器，它决定
raid-check服务何时运行。您可以根据需要配置其调度。 raid-check.service-
这是由
raid-check计时器触发时运行的 systemd raid-check服务。它执行/usr/sbin/raid-check脚本。 raid-check 脚本-
raid-check.service执行raid-check脚本。它检查数据不匹配计数，并尝试修复任何发现的错误的块。如果检测到不匹配，它会记录警告，除了 RAID1 和 RAID10 外，其中不匹配计数无法正常工作。但是，它仍然对 RAID 和 RAID10 执行检查操作，以识别并修复错误的块。
