<div> </div>
<div>I am using DRBD (8.4.5) in dual primary mode (with GFS2) on Red Hat Enterprise Linux Server release 7.0 (Cluster, Pacemaker).</div>
<div> </div>
<div>Everything workes fine only if a node crashes (i<span class="hps"> pull</span> <span class="hps">the power plug</span>), the shared directory becomes unusable: for eg. a 'ls -l' blocks until the node has rebooted normally.</div>
<div>During this situation the drbd status for the second node is Unknown/Outdated.</div>
<div> </div>
<div>I am using the configuration as supposed on the homepage.</div>
<div> </div>
<div>Am i missing something ?</div>
<div> </div>
<div>Another question: It is possible to define the time when an active node gets informed about another node crash (currently it takes about 2sec before DRBD changes the status of the crashed node) ?</div>
<div> </div>
<div>thx</div>
