I have tested mkfs.ocfs2 as Tim suggested and it works. So whole cluster 
configuration could be done by cts now and only mkfs would be ran by script.

This is class for full OCFS2 configuretion (except STONITH):

class OCFS2(CIB10):
     def add_resources(self):
         self._create('''primitive clvm ocf:lvm2:clvmd op start 
interval="0" timeout="90s" op stop interval="0" timeout="100s"''')
         self._create('''primitive cmirror ocf:lvm2:cmirrord op start 
interval="0" timeout="90s" op stop interval="0" timeout="100s"''')
         self._create('''primitive dlm ocf:pacemaker:controld op start 
interval="0" timeout="90s" op stop interval="0" timeout="100s"''')
         self._create('''primitive o2cb ocf:ocfs2:o2cb op start 
interval="0" timeout="90s" op stop interval="0" timeout="100s"''')
         self._create('''primitive ocfs2 ocf:heartbeat:Filesystem params 
directory="%s" fstype="ocfs2" device="%s" op monitor interval="20" 
timeout="40" op start interval="0" timeout="60s" op stop interval="0" 
timeout="60s"''')
         self._create('''group o2stage dlm clvm o2cb cmirror''')
         self._create('''clone c-o2stage o2stage meta interleave="true"''')
         self._create('''clone c-ocfs2 ocfs2 meta interleave="true" 
ordered="true"''')
         self._create('''colocation colo-ocfs2-o2stage inf: c-ocfs2 
c-o2stage''')
         self._create('''order order-ocfs2-o2stage 0: c-o2stage c-ocfs2''')

I put in also interval so there are no issues with them.

I understand it. But this is just class declaration. So it would be 
called elsewhere.

This is different task. It is about ext3 fs being mounted into dir 
/var/lib/mysql (I didn't specify it in case other distros have it 
elsewhere) and then mysql being ran.

Class with OCFS2 is mentioned above.

Thanks all for help.
