<p class="MsoNormal" style="text-align:left;direction:ltr;unicode-bidi:embed">Hello,<o:p></o:p></p>
<p class="MsoNormal" style="text-align:left;direction:ltr;unicode-bidi:embed"><o:p> </o:p></p>
<p class="MsoNormal" style="text-align:left;direction:ltr;unicode-bidi:embed">We built a pacemaker cluster with 2 physical servers.<o:p></o:p></p>
<p class="MsoNormal" style="text-align:left;direction:ltr;unicode-bidi:embed">We configured DRBD in Master\Slave setup, a floating IP and file system mount in Active\Passive mode.<o:p></o:p></p>
<p class="MsoNormal" style="text-align:left;direction:ltr;unicode-bidi:embed">We configured two STONITH devices (fence_ipmilan), one for each server.<o:p></o:p></p>
<p class="MsoNormal" style="text-align:left;direction:ltr;unicode-bidi:embed"><o:p> </o:p></p>
<p class="MsoNormal" style="text-align:left;direction:ltr;unicode-bidi:embed">We are trying to simulate a situation when the Master server crushes with no power.
<o:p></o:p></p>
<p class="MsoNormal" style="text-align:left;direction:ltr;unicode-bidi:embed">We pulled both of the PSU cables and the server becomes offline (UNCLEAN).<o:p></o:p></p>
<p class="MsoNormal" style="text-align:left;direction:ltr;unicode-bidi:embed">The resources that the Master use to hold are now in Started (UNCLEAN) state.<o:p></o:p></p>
<p class="MsoNormal" style="text-align:left;direction:ltr;unicode-bidi:embed">The state is unclean since the STONITH failed (the STONITH device is located on the server (Intel RMM4 - IPMI) – which uses the same power supply).
<o:p></o:p></p>
<p class="MsoNormal" style="text-align:left;direction:ltr;unicode-bidi:embed"><o:p> </o:p></p>
<p class="MsoNormal" style="text-align:left;direction:ltr;unicode-bidi:embed">The problem is that now, the cluster does not releasing the resources that the Master holds, and the service goes down.<o:p></o:p></p>
<p class="MsoNormal" style="text-align:left;direction:ltr;unicode-bidi:embed"><o:p> </o:p></p>
<p class="MsoNormal" style="text-align:left;direction:ltr;unicode-bidi:embed">Is there any way to overcome this situation?
<o:p></o:p></p>
<p class="MsoNormal" style="text-align:left;direction:ltr;unicode-bidi:embed">We tried to add a qdevice but got the same results.<o:p></o:p></p>

<p class="MsoNormal" style="text-align:left;direction:ltr;unicode-bidi:embed">We are using pacemaker 1.1.15 on CentOS 7.3<o:p></o:p></p>
