Cluster Stack Status

[Andres Rodriguez]

Dear all,

I'd like to take this opportunity to inform you all about the status of the
Cluster Stack in Ubuntu Maverick.

This cycle we targeted to get the whole cluster stack package set into Main,
however, yet again we've been unable to do so. The reason behind this is
because of two packages that have failed MIR attempts. These packages are
cluster-glue and pacemaker, and the reason behind is how libraries are
packaged within those packages. We have made the efforts to get these
changes and merge them with Debian/Upstream, however, it has
been unsuccessful, given that they see these as too much work for a package
that will disappear in the future (cluster-glue), and no need to split the
other (pacemaker), given that those libraries are runtime libraries only.

Furthermore, we were working on trying to get these changes in Ubuntu,
however we couldn't have made them before Final Freeze. The only implication
of this is that RHCS in the archives will NOT have support for pacemaker.
However, we will provide a RHCS with pacemaker support in the Ubuntu HA
Maintainers PPA soon, and we will address this issues early in Natty's
cycle.

However, not everything is sadness. As you all now from UDS-M, some services
in Ubuntu were changed from using LSB init scripts to Upstart, which broke
monitoring in the Cluster (Pacemaker specifically). However, this has now
change. Thanks to the efforts of Senko Rasic and Ante Karamatic Pacemaker
now supports the monitoring of resources that make use of Upstart!!

On the other hand, DRBD kernel module has now been included in mainline
kernel. This means that the drbd8 source package in the archive no longer
uses DKMS to install the kernel module. Now, it only provides drbd8-utils.

I think that's all. If you have any further doubts please don't doubt to
contact us.
