maybe you need interleave=true in your clones

>> Dear list
>> I am quite new to PaceMaker and i am configuring a two node active/active
>> cluster which consist basically on something like this:
>> I am using pcsd Pacemaker/Corosync:
>>  Clone Set: dlm-clone [dlm]
>>      Started: [ pbx1vs3 pbx2vs3 ]
>>  Clone Set: asteriskfs-clone [asteriskfs]
>>      Started: [ pbx1vs3 pbx2vs3 ]
>>  Clone Set: asterisk-clone [asterisk]
>>      Started: [ pbx1vs3 pbx2vs3 ]
>>  fence_pbx2_xvm    (stonith:fence_xvm):    Started pbx1vs3
>>  fence_pbx1_xvm    (stonith:fence_xvm):    Started pbx2vs3
>>  Clone Set: clvmd-clone [clvmd]
>>      Started: [ pbx1vs3 pbx2vs3]
