Anyone who can help to get this working?
Or where I can look?

Many thanks
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.

Hi,

I have a two node cluster with a DRBD, heartbeat and pacemaker (on

Debian Wheezy)

The cluster is working fine. 2 DRBD resources, Shared IP, 2 File

systems and a postgresql database start, stop, migrate, ... correctly.

Now the problem is with the lsb:apache2 resource agent.
When I try to start is (crm resource start p_ps_apache)

immediately I got an error like

p_ps_apache_monitor_60000 (node=wegc203136, call=653, rc=7,

status=complete): not running

When I start Apache from the console (service apache2 start), it

works fine

I have checked if the Init Script LSB is compatible  (see
http://www.linux-ha.org/wiki/LSB_Resource_Agents
).
All sequences tested are ok

How can I found out why crm is not starting Apache?


most likely the status url is not setup/configured.
have you checked the apache logs?

Is there a certificate passphrase when starting apache from command line?

Is it really not started, or just is not configured enough to be
successfully monitored and then monitor op fails?
What your apache logs say?
