Blueprint changed by Andres Rodriguez:
Whiteboard changed:
Work items for lucid-alpha-3:
[ivoks] package/merge latest pacemaker components: DONE
[ivoks] package/merge latest RHCS components: DONE
[ivoks] package/merge latest DRBD: DONE
[andreserl] package/merge latest keepalived (1.1.17-2): DONE
test pacemaker: DONE
test redhat-cluster-suite: TODO
test drbd: DONE
[andreserl] test keepalived+ipvsadm: DONE
test pacemaker+drbd: DONE
test redhat-cluster-suite+drbd: TODO
write MIRs for pacemaker components: INPROGRESS
create cluster task for tasksel: TODO
Work items for lucid-beta-1:
- documentation
- * Loadbalancing:
+ Documentation
+ * [andreserl] Loadbalancing:
- keepalived/ipvsadm - NAT [INPROGRESS]
* Failover:
- Pacemaker+DRBD [TODO]
Notes:
keepalived 1.1.17-2 has been merged from debian. Latest is 1.1.19 but,
according to debian Maintainer, this new upstream release introduces several
bugs that are yet to be fixed in next upstream release.
jib review 2009-12-18: This spec appears to reflect the longterm goals
of the project; which items do you expect to target for lucid-alpha3? To
be able to track progress on this blueprint, converting it to the
workitem spec would be preferred:
https://wiki.ubuntu.com/WorkItemsHowto. I would like to discuss this at
the next server meeting at the 6th of January to make sure we are
alligned.
jib review 2010-1-8: Re-targeted MIR for pacemaker and cluster stack
task to alpha3 as they are considered features and should therefor land
before Feature Freeze (Feb 16th). Anything after would require a feature
freeze exception, which I can't guarantee will happen.
These are the excerpts from UDS session:
= Ubuntu Cluster Stack =
Discussed options:
* Redhat Cluster Suite
* Heartbeat
* Going to die.
* Pacemaker
* http://clusterlabs.org/wiki/Main_Page
Upstream status:
* Movement to standardize on cluster between distros.
Plans:
* ubuntu-ha team to approach Debian team for a joint work on cluster stack
* Create templates for cluster stack to make it easier to deploy
* Management tool for setting up, and maintaining clusters
Goal for Karmic:
* Focus on Pacemaker/OpenAIS setup as a future cluster stack and keep
Redhat Cluster Suite until Pacemaker is ready.
* Update RHCS to latest version and make it easier to setup
* Documentation for RHCS/Pacemaker with DRBD.
* HA Cluster
* Add to Server Guide
* OpenAIS
* Will need a guide for migrating from RHCS to Pacemaker/OpenAIS.
* Everything is in the archive, just needs some polish.
2009-11-12 mdz: RHCS is up for discussion in server-lucid-seeds
= UDS Lucid =
== Status ==
* Stay with RHCS??
* Pacemaker: Too unstable.
* Heartbeat: Linbit is trying to push users to use Pacemaker + Heartbeat 3.0
to provide an update patch from Heartbeat 2.x
== ToDo ==
* Be more active in upstream. Ubuntu users join upstream irc
channel(#linux-cluster and #linux-ha) to ask for help.
* Documentation, Documentation, Documentation
* Would be a nice idea to also document software proxies (squid, ctdb for
samba, pgpool, etc)
* Track Linbit changes for Heartbeat 3.0 to provide and update path from
Heartbeat 2.1.x to pacemaker + heartbeat 3.0.
* What about LoadBalancing.
* keepalived for software
* If we use this one, we need to support bonding out of the box
* update packages
* ipvsadm
* ipvs-adm for hardware base
* Documentation
* RHCS
* keepalived - ipvsadm
* Pacemaker
- Corosync/OpenAIS
- Heartbeat 3.0
