Hello list
I have no technical questions at the moment, just a couple of
distribution-specific and backward compatibility questions..
1- I just wonder will Pacemaker at any time in the near future (the next
two
years) drop HeartBeat as a cluster stack?
The overhead for supporting it is minimal, and as yet there are no
core features that can't be implemented for Heartbeat as well.
If either of those two things change, then we would have to
re-evaluate how best support Heartbeat in the following release
series.
There are no plans to change anything for the upcoming 1.1 and 1.2
release series (ie. the next 2-3 years).
2- Andrew, when shall we see Pacemaker in RHEL instead of Redhat Cluster
Suite?
Red Hat has a very strict policy about discussing what "may or may not
be part of a current and/or future Red Hat products".
Having said that, I got approval to include the following in an
abstract I submitted for this years Red Hat Summit:
"Pacemaker is the scalable High-Availability cluster resource
manager intended to be the successor to rgmanager."
Although I doubt using it on top of Heartbeat would ever be an option.
If corosync/openais is the preferred option nowadays why is heartbeat chosen
as default when installing the RPMs from clusterlabs.org?
What do you mean by default?
Neither cluster stack is installed by default if you just do:
yum install pacemaker
you have to explicitly specify either corosync or heartbeat
Pacemaker pulls in hearbeat and corosync as dependency. This is what
happens on a freshly install centos 5.4 VM:
