IBMi Performance Problems with NFS (Client)

  • 1.  IBMi Performance Problems with NFS (Client)

    Posted 9 hours ago

    Hi together,

    I'm experiencing performance issues with the NFS client on IBM i with V7R4 TR11.

    I want to use the following options in the mount command:

    ===> ADDMFS TYPE(*NFS) MFS('nfs-server:/') MNTOVRDIR('/nfs') OPTIONS('rsize=524288,wsize=524288')

    I'm getting CPFA1BB back with the option keyword "rsize not within the range".

    1. However, these options are not being accepted. What would be the correct values ​​for rsize/wsize?

    2. Can I force the client to use TCP instead of UDP?

    3. Does anyone have a better idea how I can optimize NFS on my IBM i?

    Thanks in advanced

    Falko
