[Pacemaker] Help on setting order of resources

Sat Aug 18 20:16:07 UTC 2012

Short description 
----------------------- 
Corosync ignores my resources order settings. 

Final goal
-----------
Being able to HA zimbra. 

Description of the system 
----------------------------------- 
This is an Ubuntu 10.04 LTS because current stable Zimbra works in Ubuntu 10.04 and not yet in 12.04. 

I've dist-upgraded packages from: https://launchpad.net/~ubuntu-ha-maintainers/+archive/ppa as it was advised on some sites. 

My main configuration is based on this document: http://www.clusterlabs.org/doc/Cluster_from_Scratch.pdf 

I've created some OCF resource agents (for zimbra and some network stuff) on my own and I've already tested them thanks to ocf-tester and ocf-tester-py (a hack of mine of ocf-tester that allows you to test python based ocf scripts). 

Finally some packages versions: 

libcrmcluster1 1.1.6-2ubuntu0~ppa2 
libcrmcommon2 1.1.6-2ubuntu0~ppa2 
corosync 1.4.2-1ubuntu0~ppa1 
libcorosync4 1.4.2-1ubuntu0~ppa1 
lvm2 2.02.54-1ubuntu4.1ppa5 
pacemaker 1.1.6-2ubuntu0~ppa2 
libglib2.0-0 2.24.1-0ubuntu1.1~ppa1 
lvm2 2.02.54-1ubuntu4.1ppa5 
cluster-glue 1.0.8-2ubuntu0~ppa4 
libcluster-glue 1.0.8-2ubuntu0~ppa4 
resource-agents 1:3.9.2-4ubuntu0~ppa2

Long description: 
----------------------- 
I expect that system tries to start resources in the following order: 
MySystem ZimbraDataClone:Master MyZimbra 
that after expanding group members is: 
ClusterOVHFailover ClusterIP ClusterHostRoute \ 
ClusterDefaultRoute ZimbraDataClone:Master \ 
ZimbraFS ZimbraServer 
. 

If crm_mon -o shows the operation history as per my former log it seems that corosync insists on starting ZimbraData on the first place and I don't want that. 

So, that's it. Am I missing something? If you need more logs don't hesitate to ask for them. 
Thank you! 

Other questions 
--------------------- 
Where is documented the probe operation which happens to appear on crm_mon output? 

P.S.: This unanswered email is very similar to my issue: http://lists.linux-ha.org/pipermail/linux-ha/2011-May/043144.html
