&gt;Dan&nbsp;has&nbsp;shortly&nbsp;described&nbsp;the&nbsp;reason,&nbsp;as&nbsp;have&nbsp;I&nbsp;in&nbsp;my&nbsp;first&nbsp;mail&nbsp;to&nbsp;this

&gt;thread:

&gt;

&gt;&gt;&nbsp;The&nbsp;idea&nbsp;with&nbsp;the&nbsp;DRBD&nbsp;configs&nbsp;is&nbsp;to&nbsp;tell&nbsp;each&nbsp;node&nbsp;about&nbsp;the&nbsp;whole

&gt;&gt;&nbsp;picture,&nbsp;and&nbsp;each&nbsp;node&nbsp;will&nbsp;pick&nbsp;the&nbsp;information&nbsp;it&nbsp;needs.&nbsp;That's&nbsp;why&nbsp;it

&gt;&gt;&nbsp;can&nbsp;even&nbsp;work&nbsp;when&nbsp;each&nbsp;node&nbsp;sees&nbsp;a&nbsp;slightly&nbsp;different&nbsp;picture.

&gt;&gt;&nbsp;But&nbsp;don't&nbsp;try&nbsp;tricking&nbsp;DRBD,&nbsp;because&nbsp;you&nbsp;will&nbsp;only&nbsp;confuse&nbsp;yourself.

&gt;&gt;&nbsp;Just&nbsp;install&nbsp;the&nbsp;whole,&nbsp;working&nbsp;config&nbsp;on&nbsp;each&nbsp;of&nbsp;your&nbsp;nodes.

&gt;

&gt;Make&nbsp;sure&nbsp;to&nbsp;explain&nbsp;to&nbsp;your&nbsp;manager&nbsp;that&nbsp;installing&nbsp;different&nbsp;configs

&gt;on&nbsp;each&nbsp;DRBD&nbsp;peer&nbsp;is&nbsp;a&nbsp;maintenance&nbsp;nightmare.&nbsp;E.g.,&nbsp;in&nbsp;a&nbsp;year,&nbsp;you&nbsp;will

&gt;probably&nbsp;not&nbsp;be&nbsp;able&nbsp;to&nbsp;tell&nbsp;what's&nbsp;supposedly&nbsp;correct&nbsp;anymore.

&gt;

&gt;There&nbsp;is&nbsp;really&nbsp;no&nbsp;reason&nbsp;to&nbsp;set&nbsp;yourself&nbsp;up&nbsp;for&nbsp;future&nbsp;silly&nbsp;mistakes.

&gt;

&gt;Is&nbsp;there&nbsp;any&nbsp;reason&nbsp;your&nbsp;management&nbsp;insists&nbsp;on&nbsp;a&nbsp;messed&nbsp;up&nbsp;configuration?
