A Question about NFS

[Caihong Yun <superyunch@example.com>]

Hello! Everyone!
    I want to use NFS service of RedHat Linux 6.0 or 7.0 to export a PC hard disk to SGI IRIX system. I have successfully installed Linux and ran NFS server on it. But IRIX cannot write big files to the PC hard disk (only very small file can write into it.). However, IRIX can read files on the PC hard disk, no matter how big they are. Can you tell me what is the reason and how I can solve the problem. 
    Thank you for your attention!
