Your testcase is not exactly the best, but it should still cause a failover.
Please try the attached patch. I don't know why "start" was excluded at
that place. Does not make sense to me. Maybe someone can explain on the
dev list.
Imho, what you're doing should not produce what you're seeing and this
patch should fix it.
Comments please!

thanks for the reply, still the problem remains. If apache cannot be
started/restarted it is not failed over to the second node. I have two equal
servers and I want to run the virtual ip + apache (grouped) on either one of
the nodes. To test the configuration I have renamed httpd on the one node to
httpd_ else I am not sure how to simulate a non starting apache. But either way
when heartbeat is started the apache start is failed on www1test and nothing
happens then. I have attached my CIB and the logs
This is what crm_mon gives me:

Betreff: Re: [Linux-HA] Apache failover / renaming the binary
http://hg.linux-ha.org/dev/file/5072025b79b8/resources/OCF/apache
lines 516-518
another example of how to use exits codes incorrectly.
I'll commit a patch soon.
In your script: Make line 518 look like this (on all nodes!):
exit $OCF_ERR_INSTALLED
Then cleanup the resource or start the cluster from scratch and try
again. Should fix it.

Hello,
my simple active/passive cluster seems to work but when running and I do:
/opt/apache2/bin/apachectl stop && mv /opt/apache2/bin/httpd
/opt/apache2/bin/httpd_
Heartbeat is not failing over apache to node2 (Hard error: apache_2_start_0 failed with rc=6.) This is really odd because the log states "All 2 cluster nodes are eligible to run resources." but then 4 lines further it says "ERROR: unpack_rsc_op: Preventing apache_2 from re-starting anywhere in the cluster". I am using a very simple CIB with one virtual ip and apache grouped. If i stop apache manually heartbeat does restart apache fine. By the way can I configure it so that it does failover right to the other node if apache is stopped or fails? When manually stopping heartbeat the failover does work.
So I am not sure which part of my configuration or logs you need to see. I guess im missing something important here.
