Windows NFS disk thread support

    Question

  • Hi,

    I am currently testing NFS disk with testing tool: vdbench and IOzone for testing the disk which  mounted LINUX export path. The  IO threads all limit to 50. Is this the known issue or i  have to do some modify with windows machine. My windows version is : 2008 R2 standard.

    Thanks for reply in advance.

    Regards,

    KC

  • NFS disk has some thing to do with the linux operating system as mentioned IO thread are limited to 50 there is no issue with the Windows operating system that would restrict the IO for the NFS disk.

  • This is surely the issue on windows NFS disk.  If the NFS disk is mounted as linux client. for example : centos or ubuntu. They are workable  with over 50 threads simulation without R/W error happened.  Why windows can't accept those parameter? BTW, not only one testing tool shows this behavior on windows and linux client.  This probably means there is something different on windows nfs client. Is there any clue of why this limitation happened? Below is the error log used VDBENCH.
