UPDATED: Cluster Stack and PowerNap sessions at UDS-N

At UDS-N (Natty) I’ll be leading these two sessions:

  • Cluster Stack for Natty
    The Cluster stack session will be divided in two main parts. The first part we will discuss the current status of the Cluster Stack in Ubuntu, things that have been and haven’t been achieved so far, as well as the features we would like to see in the future. The second part of the session will be concentrated in the integration of the Cluster Stack with the Ubuntu Enterprise Cloud (UEC).

    The outcome of the discussion is:

    • Merge library split changes for cluster-glue, pacemaker from debian packages.
    • Complete MIR requests to finally get packages into Main.
    • Improve documentation, and add it to the Ubuntu Server Guide.
      • Docs: HA Apache2, HA MySQL, CLVM, Recommend a Cluster FS – OCFS2, Fecing, etc.
    • Automated Deployment (Look into deploying with puppet.).
      • Simple: Join a simple cluster/Virtual IP.
      • Advanced: CLVM, DRBD, Filesystems.
    • Meta-packages / Tasksel to install and join a Cluster.
    • HA for UEC.
      • Continue with the research on HA for CLC, Walrus, CC, SC
      • Eventually, write OCF RA’s for above components.
    • Investigate on providing HA *inside* the Cloud.

  • PowerNap Improvements
    PowerNap is a power management tool, created by Dustin Kirkland, that has been integrated with the Ubuntu Enterprise Cloud. However, this sessions we will discuss how to extend the functionality of PowerNap to make it available for other kinds of environments, as well as providing alternative methods of power savings for Servers.

    The outcome of the discussion is:

    • Investigate how PowerNap could tap into Upstart to monitor processes in an event driven manner rather than polling /proc.
    • Use pm-powersave for PowerNap new power save mode.
    • Contribute any new actions to pm-utils (rather keeping in PowerNap)
    • Use event based monitoring for input polling (limited to keyboard and mouse)
    • Get network monitor matching the MAC in the WoL.
    • Provide a powerwaked to track machines registered and be able to schedule poweroff’s/updates.

If you would like to know more and you are not attending to UDS personally, you can still participate remotely. Or, you can just show up at the session. I hope to see there anyone who’s interested.
