In SUSE's defence, there have occasionally been pushes for the package XYZ to ship an OCF agent for XYZ.
This is likely what happened here, nothing nefarious.  So the agent is upstream, just in a different upstream.

Reason I ask is, I noticed lots of log spamming by clvmd after upgrading from SLES 11 SP2 to SP3.  Indeed clvmd is now running with the '-d2' option, which is the new default:
