无法启动heartbeat3.0.4

redhat 6.3 yum安装 heartbeat-3.0.4 pacemaker-1.1.9 drbd-8.4.3之后，启动heartbeat报错如下：
Starting High-Availability services: Heartbeat failure [rc=6]. Failed.

查找后发现/usr/libexec/pacemaker/下有这些文件，故而针对这些文件做了软连接：
ln -s /usr/libexec/pacemaker/cib /usr/lib64/heartbeat/cib
ln -s /usr/libexec/pacemaker/stonith /usr/lib64/heartbeat/stonithd
ln -s /usr/libexec/pacemaker/attrd /usr/lib64/heartbeat/attrd
ln -s /usr/libexec/pacemaker/crmd /usr/lib64/heartbeat/crmd
一台主机成功，一台主机还是死活报这个错误，不解 啊不解！Anyone else?
