系统内部错误

设备环境：物理机

BUG现象：今天在厂里拍照之后想上传nas保存，一直卡，上传不成功，然后关闭app（苹果端）后，重新打开app可以登陆但是点击文件依旧是转圈圈无法加载，以为是网卡了，没理会，过了十多分钟故障依旧，然后强制重启了nas，然后居然链接不上了，起初以为是光猫断 电ip变更（IPV6+域名解析访问方式）域名没有解析成功所以访问不成功，就没理会了，晚上回到家发现局域网也进不去后台了，windows win+R ping nas ip 前3秒有跳动后面直接卡死，无奈接上显示器看看什么情况，屏幕提示如下：

此时机器 硬盘出现异响（机械硬盘，像是机械硬盘通电后，然后突然断 电了之后的声音）以为是哪个硬盘坏了，一个一个逐一排查，拔了某一个硬盘电源线后可以进系统了，然后重新插上异响的硬盘电源，重启后系统也可以识别得到，但是就是挂载不了，点挂载提示系统内部错误

出现频率：（必现）
