Why not to 1.0.9.1? [BS] Because when I checked the link http://www.clusterlabs.org/wiki/Get_Pacemaker it seemed to indicated that 1.0.8 was the last one fully tested with the rest of the stack (heartbeat, etc). Are there fixes in 1.0.9 in this area?

Yes, sounds like it. Where is the score set? Wouldn't "resource demote" do the right thing? [BS] I used the ~October 2009 DRBD agent as a reference. The "crm_master -Q -l reboot -v -10" call is made at the end of the start() entry point in the agent. I am not sure what you mean by "resource demote" > My configuration is: > > node $id="f4e5e15c-d06b-4e37-89b9-4621af05128f" mgraid-bob00001-0 > primitive SSJ5AMKP00009010REPK ocf:omneon:ss \ > params ss_resource="SSJ5AMKP00009010REPK" > ssconf="/var/omneon/config/config.J5AMKP00009010REPK" \ > op monitor interval="3s" role="Master" timeout="7s" \ > op monitor interval="10s" role="Slave" timeout="7" \ > op stop interval="0" timeout="100" \ > op start interval="0" timeout="120" \ > meta id="SSJ5AMKP00009010REPK-meta_attributes" > ms ms-SSJ5AMKP00009010REPK SSJ5AMKP00009010REPK \ > meta clone-max="2" notify="true" globaally-unique="false" You have a typo here.
