[Pacemaker] corosync stop and consequences

[andreas graeper]

(in addition)
n1 (former active/master node) is still stopped
n2 : corosync stop + start
now drbd is slave on n2 and nothing else starts

there is a location-constraint
<rsc_location rsc="ms_drbd_r0" id="drbd-fence-by-handler-r0-ms_drbd_r0">
        <rule role="Master" score="-INFINITY"
id="drbd-fence-by-handler-r0-rule-ms_drbd_r0">
          <expression attribute="#uname" operation="ne" value="lisel1"
id="drbd-fence-by-handler-r0-expr-ms_drbd_r0"/>
        </rule>
      </rsc_location>

Master, -INF uname __ne__ lisel1
i would interprete :
 master must not start where ?node-name? is not lisel1

but this node (n2) is 'lisel1'
i have deleted that location-constraint and corosync-stop+start again. did
not help.
