  == Agenda ==
  
   * Current Cluster Stack:
     - RHCS (3.0.12)
       + dlm_controld.pcmk/gfs_controld.pcmk
     - Pacemaker/corosync/heartbeat (1.0.10):
       + RA's handle above.
  
   * Discuss the adoption of the new software versions as there have been several upstream changes, and different distributions are adopting different components.
     * RHCS (3.1):
       - RHCS (dlm, cman, etc), fence-agents, resource-agents, gfs2-utils
       - gfs-pcmk, dlm-pcmk dropped.
     * Pacemaker 1.1:
       - Pcmk + Corosync + cman (to use dlm_controld/gfs_controld)
     * resource-agents
       - Linux-HA and RHCS RA's merged in a single source.
     * MIR fence-agents
       - Cobbler uses it.
  
   * DRBD 8.3.X/DRBD 8.4.X
   * Nova Components HA (following discussion from the OpenStack Design Summit)
   * Continue with the work on the Ubuntu Cluster Stack to complete previously defined work items.
   * Obtain feature requests and discuss the customization of the cluster stack for Ubuntu.
   * Cloud HA - Pacemaker Cloud Policy Engine:

  == Session Notes ==
  
  == Actions ==
   * Move forward with OCFS2 as the supported clustered FS
   *  Keep RHCS 3.0 for DLM's only.
      - dlm_controld.pcmk/gfs_controld.pcmk
      - keep shipping gfs2-tools (and make sure it's ok)
      - upgrade to latest 3.0.x that contains .pcmk (3.0.17)
   *  Package fence-agents/resource-agents
   *  Upgrade pacemaker to 1.1
   *  Investigate and resolve ARM related issues within OCFS2, test
   *  Move from cluster-agents to resouce-agents
   *  Link up with openstack and upstream to compile a list of HA requirements
   *  DRBD 8.4 if is shipped in mainline kernel Oneiric ships.
   *  ***Documentation***
   *  Sort out PPAs (ubuntu-ha-maintainers becomes main PPA, all other go away)
