Hi Pacemaker guru's

I have installed pacemaker successfully and I have setup a cluster with the
following configuration:

node tsparxdb01
node tsparxdb02
primitive ClusterIP ocf:heartbeat:IPaddr2 \
params ip="192.168.1.254" cidr_netmask="32" \
op monitor interval="30s" \
meta target-role="Started"
primitive Data ocf:linbit:drbd \
params drbd_resource="data" \
op monitor interval="60s" \
op start interval="0" timeout="240s" \
op stop interval="0" timeout="240s"
primitive DataFS ocf:heartbeat:Filesystem \
params device="/dev/drbd/by-res/data" directory="/data" fstype="ext4" \
op start interval="0" timeout="60s" \
op stop interval="0" timeout="60s"
primitive MySQL lsb:mysql \
op monitor interval="60s" timeout="120s" \
op start interval="20" timeout="120s" \
op stop interval="20s" timeout="120s"
group Server-MySQL DataFS MySQL ClusterIP
ms DataMaster Data \
meta master-max="1" master-node-max="1" clone-max="2" clone-node-max="1"
notify="true"
colocation DataFS_on_DataMaster inf: Server-MySQL DataMaster:Master
order DataFS-after-DataMaster inf: DataMaster:promote Server-MySQL:start
property $id="cib-bootstrap-options" \
dc-version="1.0.8-042548a451fce8400660f6031f4da6f0223dd5dd" \
cluster-infrastructure="openais" \
expected-quorum-votes="2" \
stonith-enabled="false" \
no-quorum-policy="ignore"
rsc_defaults $id="rsc-options" \
resource-stickiness="100"


Everything except the MySQL resource is working correctly (state 1):

The MySQL resource keeps trying to start, but after a while I will see this
(state 2):

     MySQL      (lsb:mysql):    Stopped
     ClusterIP  (ocf::heartbeat:IPaddr2):       Started tsparxdb02

Failed actions:
    MySQL_monitor_60000 (node=tsparxdb02, call=62, rc=7, status=complete):
not running

And then it will go back to the previous state 1.

I have tried to use both RA ocf:heartbeat:mysql and lather the lsb:mysql.

My MySQL startup script seems to be LSB compliant since, it gives on all the
start/stop/status commands the correct result 0 or 3.

Anyone any idea what could be wrong. Attached you will find the snippet of
corosync.log that show when the switch between state 1 and state 2 occurs.

Hoping you can help me.
