<div class="gmail_quote">Hi,<br><br>I'm testing split-brain in a master/slave scenario with dopd and have some doubts about the automatic recovery procedure. The steps I took were:<br><br>1º Unplug the crossover cable<br>
<br>Master:<br><br>Primary/Unknown ds:UpToDate/Outdated<br>
<br>Slave:<br><br>StandAlone ro:Secondary/Unknown ds:Consistent/DUnknown<br><br>2º Plug the cable back on:<br><br>Both nodes remain with the same state: Update/Outdated and Consistent/Unknown<br><br>My question is: shouldn't the slave rejoin/resync to the master automatically after I plug the cable?<br>
<br>I have to manually run: "drbdadm adjust all" to recover it. <br><br>My conf (centos 5.3; drbd 8.3.1; heartbeat 2.99)<br><br>/etc/drbd.conf<br><br>global<br>{<br>usage-count no;<br>}<br>common<br>{<br>syncer<br>
