使用 NFS 传输文件时出现此错误，并且文件大小被截断
有人能给我提示吗？我们尝试了 2GB，文件在 400 MB 时被截断。

答案1
另一边的日志说了什么？我怀疑另一边有问题（文件系统已满、不支持大文件等）
根据 /usr/include/errno.h (https://stackoverflow.com/questions/503878/how-to-know-what-the-errno-means）
#define EBUSY 16 /* Device or resource busy */
NFS 错误和 errno.h 代码只有前几个数字相同。当数字达到 16 时，它们就不相关了。然而，这通常是一个线索。http://utcc.utoronto.ca/~cks/space/blog/linux/NFSKernelErrorExplained
