does anyone know how it happen?or how to solve it?

Answer 1

This is happen due to the read only file.

I think this is due to the EIO comes from bad_file_flush in your file. It seems when the kernel has any failure accessing an file, it transforms the open file description to a pseudo-open-file of with bad_inode_ops as its file ops. I can't find the code that does this for FAT-based file systems, but perhaps there's some generic code.

Since the FileChannel cache data I think you need to call force() before you close() the FileChannel
