Blueprint changed by Andres Rodriguez: Whiteboard changed: Work items: [andreserl] Finish packaging resource-agents: DONE [andreserl] Finish packaging fence-agents: DONE [andreserl] Upgrade pacemaker to 1.1.X and submit debian dir to Debian: DONE [andreserl] Upload fence-agents: DONE [andreserl] Upload resource-agents: DONE [andreserl] Keep RHCS for DLM (gfs_controld.pcmk/dlm_controld.pcmk) and gfs2-tools: DONE [andreserl] Remove installation of resource agents from rgmanager: DONE [andreserl] Remove installation of fence agents from source: DONE [andreserl] Sync/Merge pacemaker 1.1 from Debian: TODO - [andreserl] MIR resource-agents: TODO - [andreserl] MIR fence-agents: TODO + [andreserl] MIR resource-agents: INPROGRESS + [andreserl] MIR fence-agents: INPROGRESS [andreserl] Request demotion of cluster-agents: TODO [andreserl] Upgrade DRBD 8.4 if Oneiric Kernel ships it: TODO [andreserl] Link up with openstack and upstream to compile a list of HA requirements: DONE [andreserl] Sort out PPAs (ubuntu-ha-maintainers becomes main PPA, all other go away): TODO [andreserl] Evaluate upgrade path 1 or path 2: TODO Path 1: Update RHCS to latest 3.0.X (3.0.17 no longer maintained by upstream): TODO Path 2: Evaluate if RHCS should be updated to 3.1 (needs testing for OCFS2/GFS2 with pacemaker+corosync+cman. Heartbeat will no longer be used for GFS2/OCFS): TODO Upgrade to RHCS 3.1: TODO Finish packaging gfs2-utils: TODO Upload gfs2-utils: TODO MIR gfs2-utils: TODO Update default Pacemaker configuration to reflect upstream changes: TODO Upstartify corosync (upstart does not stop correctly stop corosync threads): POSTPONED Include new RHCS and related packages into natty: POSTPONED Look into automated deployment with puppet (Simple: VIP/ Advanced: DRBD, CLVM, etc): POSTPONED Add meta-package/tasksel to install simple cluster and join it: POSTPONED Document for HA with OCFS2: POSTPONED Document for CLVM: POSTPONED Include documentation in Ubuntu Server Guide: POSTPONED == 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: http://www.redhat.com/summit/2011/presentations/summit/whats_new/thursday/dake_th_1130_high_availability_in_the_cloud.pdf == 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)
