NFS mounted disk owner

  1. NFS mounted disk owner

    Who should be ( performance wise ) the file system owner mounted as
    NFS between two hosts . The Reader or the Writer process?
    EG.
    HostA owns FS ------> HostB sees FS ..
    Should processes in HostA be writers and processes in HostB the
    Readers?
    Thank you.

    Its a local disk on HostA, which must be "exported". On HostB, its
    mounted.

    I don't understand what you mean by "Reader" or "Writer" process in
    this context.

    Are you asking about user mode implementations of NFS
    compared to kernel mode implementations, or do you have
    some strange notion of how NFS works without having read
    any of the documentation?

    NFS is a filesystem so it *implements* ownership of files and
    mount points.
