    Orangefs: kernel client part 1 · f7ab093f
    Mike Marshall authored
    OrangeFS (formerly PVFS) is an lgpl licensed userspace networked parallel
    file system. OrangeFS can be accessed through included system utilities,
    user integration libraries, MPI-IO and can be used by the Hadoop
    ecosystem as an alternative to the HDFS filesystem. OrangeFS is used
    widely for parallel science, data analytics and engineering applications.
    
    While applications often don't require Orangefs to be mounted into
    the VFS, users do like to be able to access their files in the normal way.
    The Orangefs kernel client allows Orangefs filesystems to be mounted as
    a VFS. The kernel client communicates with a userspace daemon which in
    turn communicates with the Orangefs server daemons that implement the
    filesystem. The server daemons (there's almost always more than one)
    need not be running on the same host as the kernel client.
    
    Orangefs filesystems can also be mounted with FUSE, and we
    ship code and instructions to facilitate that, but most of our users
    report preferring to use our kernel module instead. Further, as an example
    of a problem we can't solve with fuse, we have in the works a
    not-yet-ready-for-prime-time version of a file_operations lock function
    that accounts for the server daemons being distributed across more
    than one running kernel.
    
    Many people and organizations, including Clemson University,
    Argonne National Laboratories and Acxiom Corporation have
    helped to create what has become Orangefs over more than twenty
    years. Some of the more recent contributors to the kernel client
    include:
