[Linux-ha-dev] libglue2 dependency missing in cluster-glue
Hi as some of you might have seen on the pacemaker list, I tried to install a 3 node cluster and there were ipc issues reported by the cib and therefore the cluster could not start correctly. The reason was that libglue2 and cluster-glue were not installed from the clusterlabs repository, as the rest of the packages were, but instead they were pulled from the original opensuse repository in an older version. So I went and updated cluster-glue with the version from the clusterlabs repository. Nothing changed though. rpm -qa|grep glue revealed that libglue2 was still the old version while cluster-glue was updated. Looking at the package dependencies, I think the problem is that cluster-glue does not depend on package libglue2 (while they do the other way around). So one error, which I could improve, was that the installation instructions on the clusterlabs site did not mention libglue2 and cluster-glue. They do now which should prevent others who follow those instructions. The dependency thing is up for grabs ;) Regards Dominik ___ Linux-HA-Dev: Linux-HA-Dev@lists.linux-ha.org http://lists.linux-ha.org/mailman/listinfo/linux-ha-dev Home Page: http://linux-ha.org/

Hi Dejan The reason was that libglue2 and cluster-glue were not installed from the clusterlabs repository, as the rest of the packages were, but instead they were pulled from the original opensuse repository in an older version. This is what I found in pacemaker.spec.in in the repository: Requires(pre): cluster-glue = 1.0.6 Which version of glue was that older version? 0.9.1 So you're saying pacemaker depends on cluster-glue 1.0.6. Well, that was not installed when I installed pacemaker. And I did not use --nodeps or such thing. Instead, that old version was installed from the original opensuse repositories. So I went and updated cluster-glue with the version from the clusterlabs repository. Nothing changed though. rpm -qa|grep glue revealed that libglue2 was still the old version while cluster-glue was updated.

So you're saying pacemaker depends on cluster-glue 1.0.6. Well, that was not installed when I installed pacemaker. And I did not use --nodeps or such thing. Hmm, then it looks like the spec file used there was different. Is that clusterlabs.org? That'd be strange.

[Linux-ha-dev] Patch to ocf:heartbeat:IPaddr2 to check if link status is up
IPAddr2 puts the interface up on start and down on stop.
But its not able to detect an UP or DOWN change in status or monitor.
Therefore an ifconfig interface down from a thrird program or a
careless administrator would drop the link without pacemaker noticing!
The attached patch tries to fix that
