Ken wrote:
"
Pore through the daemon.log entries around the time you do your "resource start". There are a variety of log tags (cib, lrmd, pengine, etc.), so grepping usually isn't worth the bother. The main difficulty is the verbosity and the fact that it's not obvious what's expected and what indicates trouble. Not every message with the word "error" in it is an error. ;-)

But if you go line by line through all that, you can usually find a telltale indicator of what really went wrong.

Out of curiosity, why do you put apache in your cluster resources? If people are connecting to your virtual IP, there's generally no harm in having apache continue running on the other node. But if your DRBD is master-slave and apache can't run without it, that would make sense.
"

I would start by working out when '[notice] caught SIGTERM, shutting down' appears relative to what the cluster is doing.
If its prior to the failed monitor operation - then some external actor is causing a failure and pacemaker is merely detecting it.
If it happens afterwards, then it is likely that the monitor operation in the LSB script is broken somehow - add logging (somehow) to figure out what's going wrong.
