Hi Listers,
I am trying to test Linux-HA with DRBD.
The active/passive test environment consists of:

-        zVM 5.4

-        SLES10-SP2

-        2 nodes/guests ( lnodbbt & lnodbct )

-        Oracle
I have managed to setup drbd and to mount the database filesystem on lnodbbt ( active/master ).
Now I want to bring up Oracle.  I have created a resource ORADB and am using the ocf scripts to start oracle which doesn't work.  However, I can manually run the ocf startup script and oracle comes up.
My questions follow:

1.      Should I be using the LSB startup scripts instead of the ocf script ?

2.      How do I configure drbd so that lnodbbt is the master and lnodbct is the slave ?

3.      Do I have to set up any constraints for the ORADB resource so that it only starts up on the guest that has the /dbms mounted and what would the constraints be ?

Attached is my /etc/drbd.conf and etc/ha.d/ha.cf and ha-logs from lnodbbt ( the active/master ) guest.
Any help or pointers would be much appreciated.
