[Linux-ha-dev] clones, groups and notify

[Raoul]

why do you need a group for myOCFS2 inside the clone?
try using a primitive instead:

     <clone id="clone_ocfs2_www" globally_unique="false">
         <instance_attributes id="clone_ocfs2_www_ia">
           <attributes>
             <nvpair id="clone_ocfs2_clone_max" name="clone_max"
value="2"/>
             <nvpair id="clone_ocfs2_clone_node_max" name="clone_node_max"
value="1"/>
             <nvpair id="clone_ocfs2_www_notify" name="notify"
value="true"/>
             <nvpair id="clone_ocfs2_www_globally_unique" name="notify"
value="false"/>
             <nvpair id="clone_ocfs2_www_role" name="target_role"
value="started"/>
           </attributes>
         </instance_attributes>
         <primitive class="ocf" id="ocfs2_www" provider="heartbeat"
type="Filesystem">
           <operations>
             <op id="ocfs2_www_mon" interval="120s" name="monitor"
timeout="60s"/>
           </operations>
           <instance_attributes id="ocfs2_www_ia">
             <attributes>
               <nvpair id="ocfs2_www_attr_0" name="device"
value="/dev/drbd0"/>
               <nvpair id="ocfs2_www_attr_1" name="directory"
value="/data/www"/>
               <nvpair id="ocfs2_www_attr_2" name="fstype" value="ocfs2"/>
             </attributes>
           </instance_attributes>
         </primitive>
       </clone>

cheers,
