Hello Emmanuel
 
config file here:
I copied only some parts of  it
 
<?xml version="1.0"?>
<cluster alias="testsapcluster" config_version="169" name="testsapcluster">
        <fence_daemon clean_start="0" post_fail_delay="0" post_join_delay="3"/>
        <clusternodes>
                <clusternode name="sapclsn1.sedas.com" nodeid="1" votes="1">

                                <method name="1">
                                        <device name="fence_node1"/>
                                </method>
                        </fence>

Hello AKIN

can you show me your full cluster config and your cluster log?

If you think it's a problem with quorum disk, you can monitor the operation speed with this command

mkqdisk -d -L
