外挂USB硬盘随机改变盘符导致系统报存储空间损坏

qb574500110

设备环境：物理机CPU intel8100 主板msi B360M 虚拟机pve8.3 q35安装fnos0.8.29

BUG现象：主机通过USB3.0接口挂载移动硬盘，pve直通给fnos。硬盘能够分配存储空间正常使用，但是会在系统运行十几个小时后出现“存储空间已损坏”提示，存储空间无法访问。通过重启fnos虚拟机后可以重新识别存储空间，这种情况目前在运行了4天中已出现了3次，平均都是10个多小时出现问题。查看系统日志发现在出问题时sda（外部usb硬盘）会断开连接，然后usb硬盘重新枚举并识别为sdc系统检查出错。下面是日志片段：

这个硬盘没有独立供电，假设是供电不够稳定导致有概率使usb断开连接。在断开后usb又立即进行了枚举并正确识别了设备的VID、PID以及设备描述信息，说明设备还是能够正常使用的，但是系统分配了一个新的盘符，这可能是导致系统无法识别存储空间的原因。系统使用uuid绑定盘符能不能解决这个问题

外接硬盘休眠会导致系统识别成存储空间损坏

日志中有休眠和唤醒的记录通常都没有问题，出现问题时的情况是USB意外断开连接，之后重新枚举时盘符改变了，导致硬盘无法被正确识别

那要检查一下接口和线材是否松动
