Request for pacemaker / cluster-glue packages

RHEL/CentOS/Fedora 7 Pacemaker Package was built without 'legacy' plugin support

'Legacy' pacemaker plugins provide useful, well tested resource providers for linux high availability / the open cluster framework (OCF), most of them are still very widely used / relied upon and are a potentially blocker for people wanting to build modern linux clusters based on RHEL/CentOS 7 and beyond.

In a perfect world RHEL/Fedora would simply build the pacemaker package with the --with stonithd flag and reinstate the cluster-glue package that was present in 6, However I know how hard it is to get those kind of changes made after a release (and probably for good reason).

  • There is only one difference when building the pacemaker package that enables this that requires no additional packages or code.
  • There are three parts to this request - they are neither complex or fraught with dependency nightmares.
  1. Provide the package pacemaker with legacy-plugins enabled when the RPM is generated.
  2. Provide the cluster-glue & cluster-glue-libs packages that are missing from RHEL/CentOS 7 but is still widely used. (Also included in the latest OpenSUSE distributions.)
  3. Provide the crmsh package that is missing in RHEL/CentOS 7 but is widely used by many tools to manage linux HA clusters.
  • Here is the link to the official pacemaker RPM spec with the --with stonithd option.

If it helps at all I am happy to provide the packages I have built / picked and we have deployed very successfully with CentOS 7.


Required Steps

  1. Ensuring pacemaker is built with legacy-plugin support simply requires building the pacemaker package with --with stonithd:
rpmbuild -ba --with stonithd pacemaker.spec
  • I've also mirrored all the pacemaker packages built --with stonithd to my RPM repo here
  1. Add the cluster-glue and cluster-glue-libs packages to the repo.
  • It's available from OpenSUSE and works with CentOS 7 (Which is what we're currently doing).
  • Version 1.0.12 or greater is required rpmfind search rpmfind package
  • I've also mirrored these to my RPM repo here
  1. Add the crmsh package to the repo:
  • It's available from OpenSUSE and works with CentOS 7 (Which is what we're currently doing).
  • Version 2.1 or greater is required rpmfind search rpmfind package
