  • 482664ddb   orangefs: add features op ... Browse Code »

    This is a new userspace operation, which will be done if the client-core
    version is greater than or equal to 2.9.6. This will provide a way to
    implement optional features and to determine which features are
    supported by the client-core. If the client-core version is older than
    2.9.6, no optional features are supported and the op will not be done.

    The intent is to allow protocol extensions without relying on the
    client-core's current behavior of ignoring what it doesn't understand.

  • 8bb8aefd5   OrangeFS: Change almost all instances of the string PVFS2 to OrangeFS. ... Browse Code »

    OrangeFS was formerly known as PVFS2 and retains the name in many places.

    I leave the device /dev/pvfs2-req since this affects userspace.

    I leave the filesystem type pvfs2 since this affects userspace. Further
    the OrangeFS sysint library reads fstab for an entry of type pvfs2
    independently of kernel mounts.

    I leave extended attribute keys user.pvfs2 and system.pvfs2 as the
    sysint library understands these.

    I leave references to userspace binaries still named pvfs2.

    I leave the filenames.

  • f7ab093f7   Orangefs: kernel client part 1 ... Browse Code »

    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:
