[DRBD-user] Node w/ lost networking remains primary

[Dan Gavenda]

Hi, 

I am a newbie to drbd/heartbeat.  We have two servers/nodes and have it  working 
w/ one exception.  When the master loses networking, it stays  primary.  When it 
regains networking, it causes a 2pri split brain since  the slave took primary.  
What is the best method to have the master  change states when it loses 
networking?  We have tried using dopd and  ipfail which don't seem to do that 
probably due to lack of proper  configuration.  This is were help would be 
greatly appreciated. 


Failover works properly when the master is halted/rebooted.  The problem  
happens only when it loses networking. 



Here are the configs.
