Sorry for sending this again. The log format was a bit messy in the previous one.
Thanks for your hints. I went through the cluster logs more carefully. By comparing the logs from the two nodes, the real different is after the line info: process_lrm_event: LRM operation fs_mysql_start_0 On node arsvr1, after that line we got a confirmation on Action fs_mysql_start_0 as such info: match_graph_event: Action fs_mysql_start_0 (8) confirmed on arsvr1 and then went on to Initiating action 9: start mysql_start_0 on arsvr1 (local). However on node arsvr2, we never see the confirmation from Action fs_mysql_start_0. So mysql_start_0 is never called. But the strange thing is, I can see the drbd partition of fs_mysql is properly mounted on arsvr2. Anyone knows what might stop arsvr2 to run that Action fs_mysql_start_0 (8) confirmed? Thanks in advance. Here are the logs from the two nodes.
