[ogfs-dev]OLS paper

Hi all,

I'm thinking about sending the following in as a paper proposal for
Ottawa Linux Symposium.  I'd welcome your comments:



Inter-Node Distributed Locking, Shared Applications, and Shared
Filesystems:
  OpenDLM, SAF Locking, and OpenGFS Working Together for Your Cluster


OpenDLM is a truly Distributed inter-node Lock Manager.  We'll describe
how
OpenDLM distributes lock management, storage, and recovery among the
nodes
of a cluster, eliminating any Single Points of Failure (SPOFs).

We'll also describe two uses of OpenDLM:

1)  OpenGFS shared filesystem can now use OpenDLM, replacing OpenGFS'
legacy
    memexp lock protocol that has a SPOF in its lock storage.  We'll
describe
    the locking (and cluster management) architecture of OpenGFS,
including:

    a).  the "g-lock" (global lock) layer,
    b).  g-lock's available plug-in lock protocols (e.g. OpenDLM),
    c).  a genericized version of g-lock, which is useful for any sort
of
         inter-node locking (even non-filesystem).

2)  Service Availability Forum (SAF) locking interface implementation
for using
    OpenDLM for user-space applications.
