<p class="MsoNormal">Sometimes it seems like Pacemaker fails over an entire cluster when only one resource has failed, even though no other resources are dependent on it. Is that expected behavior?<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">For example, suppose I have the following colocation constraints…<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">filesystem with drbd master<o:p></o:p></p>
<p class="MsoNormal">vip with filesystem<o:p></o:p></p>
<p class="MsoNormal">mysql_01 with filesystem<o:p></o:p></p>
<p class="MsoNormal">mysql_02 with filesystem<o:p></o:p></p>
<p class="MsoNormal">mysql_03 with filesystem<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">…and the following order constraints…<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">promote drbd, then start filesystem<o:p></o:p></p>
<p class="MsoNormal">start filesystem, then start vip<o:p></o:p></p>
<p class="MsoNormal">start filesystem, then start mysql_01<o:p></o:p></p>
<p class="MsoNormal">start filesystem, then start mysql_02<o:p></o:p></p>
<p class="MsoNormal">start filesystem, then start mysql_03<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Now, if something goes wrong with mysql_02, will Pacemaker try to fail over the whole cluster? And if mysql_02 can’t be run on either cluster, then does Pacemaker refuse to run any resources?<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I’m asking because I’ve seen some odd behavior like that over the years. Could be my own configuration mistakes, of course.
