我最近购买了一台旧的 Lenovo ix4-300d NAS（过时型号）。一段时间后它开始显示文件系统错误。
我尝试在通过 SSH 使用 putty 连接到设备后运行 fsck，这在空运行中确实识别出了可纠正的问题。但是，尽管卸载了驱动器和共享，fsck 仍会终止并显示错误，指出驱动器仍在使用中。定影器不显示任何正在使用该驱动器的内容。我还通过网络界面禁用了这些协议。我无法从 Web 界面使用文件系统扫描仪的原因是它不起作用。我也无法在根 FS 上触摸forcefsck，因为根 FS 是只读的，并且触摸的文件在重新启动时就会消失。
任何帮助将不胜感激。非常感谢。

[After trying to run fsck on unmounted drive]
root@AdanetCloud:/# fsck /dev/mapper/7d2470b7_vg-lv9953e62
fsck 1.42.5 (29-Jul-2012)
e2fsck 1.42.5 (29-Jul-2012)
/dev/mapper/7d2470b7_vg-lv9953e62 is in use.
e2fsck: Cannot continue, aborting.
答案1
我能够解决这个问题。
启用 SSH（支持模式）并登录到设备 [UN: root; PW：soho+密码]使用SSH客户端（例如Windows上的Putty或Android上的JuiceSSH）。
通过 Web GUI 关闭所有可访问驱动器、NFS、Windows 共享、媒体服务器的“协议”[我之前没有禁用媒体服务器，因此 raid 驱动器正在使用中]。
卸载所有 NFS 共享文件夹和池安装 [使用 df -h 查看哪些文件夹安装到您的驱动器（对我来说是 /dev/mapper/7d2470b7_vg-lv9953e62）并使用 umount。
卸载所有内容后，在 RAID 驱动器上运行 fsck，运行 fsck -yfVC /dev/mapper/7d2470b7_vg-lv9953e62。
然后让它运行并纠正发现的任何错误。您可以单独运行 2 次，以确保修复所有错误。
如果存在大量碎片 (>1%)，请在安装文件系统后重新启动后运行 e4defrag /dev/mapper/7d2470b7_vg-lv9953e62 （与 fsck 不同，fsck 不会在已安装的文件系统上运行）
运行 iostat -x 并检查每个驱动器的 %b。与其余的相比，表现不佳（或即将失败）的等待时间较长，并且通常 %b 将接近 100%。该驱动器需要更换。
重新启动（立即运行重新启动或关闭）
感谢大家。
