<table cellspacing="0" cellpadding="0" border="0" ><tr><td valign="top" style="font: inherit;">Hello --<br><br>We've experienced a weird problem 3 times in the last month on different clusters.<br><br>Environment:<br>- Pacemaker 1.0.9.1-1<br>- Corosync 1.2.5-1<br>- RHEL5.4<br>- 2 nodes<br><br>We run a simple configuration with a master/slave resource, appended below.<br><br>Three times we have found different clusters in a state where both instances are slaves and Pacemaker seems perfectly happy with this.&nbsp; Looking at the configuration (cib.xml) reveals that the target-role attribute for the master/slave resource has changed from Master to Started.&nbsp; Changing the value of this attribute back to Master fixes the problem immediately.<br><br>Any ideas what might be causing this?&nbsp; Nobody is doing it manually.<br><br>I'll hold off on logs until asked, this stuff can get voluminous.<br><br><br>Thanks, Rick
