Modify YKD to select primary component and execute the synchronization operation only in the main partition. In the non-primary partition, no new requests are allowed - they are all returned with the error code SA_AIS_ERR_TRY_AGAIN. git-svn-id: http://svn.fedorahosted.org/svn/corosync/trunk@878 fd59a12c-fef9-0310-b244-a6a79926bd2f
