<br>i will simulate the same process couple of time more.. and will come back toyou ...<br>
<br>Thanks again on both <br><div class="HOEnZb"><div class="h5"><br><br><br><div class="gmail_quote">On 16 November 2011 13:00, Felix Frank <span dir="ltr"><<a href="mailto:ff@mpexnet.de" target="_blank">ff@mpexnet.de</a>></span> wrote:<br>

</div>so if drbd1 is connected...<br>

</div>...what is it connected to? I wonder.<br>
<br>
Getting both your local nodes in Secondary/Secondary is fine. The you<br>
must make one Primary and bring up the stacked resources.<br>
<br>
If you do get split brain between your local stacked resources and the<br>
remote resources, you do have to resolve it as hinted by Andreas.<br>
<br>
Bear in mind that your victim has stacked resources, you will have to<br>
discard its data using drbdadm --stacked.<br>
