[ClusterLabs] Pacemaker 1.1.12 does not compile with CMAN Stack.

[Somanath Jeeva]

Hi ,

Thanks for your extended support and advise. I would like to give some background information about my exercise, which will give some fair idea to you folks. 

We are planning to use pacemaker + Corosync + CMAN stack in RHEL 6.5 OS. For the same, we are trying to collect the source from Clusterlab.

Initially we got the Pacemaker and Corosync Source successfully from Clusterlab and we were unable to fetch the source for CMAN from Cluster lab.

As you suggested, We already tried to use the latest set of Pacemaker with its prerequisites (Corosync) on top of RHEL 6.5, but it fails due to dependencies of RHEL 7.x Components (Systemd).

So we are requesting you to provide the below information.

Is it possible for me to get the source code for CMAN from Cluster lab ??? (since we are planning to use it for our production purpose, that's why we don't want to go with Red hat sites (even for Publicly available)).


With Regards
Somanath Thilak J

midly put, it's like trying to run with dinosaurs; that version of pacemaker together with that effectively superseded bundle of other components will hardly receive any attention in 2019.

But let's assume there's a reason.

Well, pacemaker alone won't magically bootstrap these other prerequisites, you need to take an effort of grabbing them as well.

For CMAN in particular, look here:

https://pagure.io/linux-cluster/cluster/blob/STABLE32/f/cman
https://ftp.redhat.com/pub/redhat/linux/enterprise/6Server/en/RHS/SRPMS/cluster-3.0.12.1-73.el6.src.rpm

Easy, no /etc/init.d/cman around, for the mentioned reason.

Still, I am not sure how far you'll get, sounds like an uphill battle.
Settling with the rather recent state of development may avoid significant chunks of troubles, incl. those that were only fixed in later versions of pacemaker.

I think having "cman" enumerated amongst features might be enough, but once you'll get past the "cman: unrecognized service" phase, you shall see.

Hope this helps.
