🎸安x

设备环境：物理机、局域网、系统0.9.13

BUG现象：从任意存储空间3（U盘）向另一块机械硬盘中复制或移动文件，上传115、夸克等网盘，2G-10G左右会出现提示I/O错误

出现频率：必现

大文件上传夸克或者其他网盘的时候，如果带宽不够，已经处理好的文件，会暂存在内存里面，等待上传，长时间无法完成传输的话，cpu一直被占用，就会报io错误，这个是已知的。 后续有计划针对这个情况做优化，但是需要做比较大的改动，要晚一点实现。

网盘的原因技术已经解释了，但是你的情况复制到物理磁盘也会遇到，更像是u盘本身链接上的问题，可以提供发生io错误前和后的dmesg的所有信息供技术参考。另外你可以先尝试换一个usb存储设备尝试复现此现象。

换过U盘也是这样，U盘和U盘也是这样。但是移动或复制2G以下文件是正常可以，没有问题的，2G以上就报错了！

我这儿好像也碰到了，接上显示器再次拷贝文件，有大量错误提示，dmesg里也有，
