Hi Andrew, Thanks for the reply. I have a couple of more questions below. I have seem to have two main problems: isolated node updating CIB; corosync behaviour to ifdown.

Would you consider this a bug, or is there a case where this behaviour is desired? In the meantime, I have a run script over the weekend that brings down the network on the current drbd master, randomly using one of two options: ifdown ethX; or add iptables rule to block all incoming and outgoing packages. All of the roughly 350 block ports scenarios were successfully recovered (i.e. no split-brain), whereas 130 out of 350 ifdown scenarios resulted in split-brain (the script automatically repaired split-brain between test interations). (Note that in order to aggravate the problem, these tests are based on using stonith with an artificial delay before reset, and ensuring that crm-fence-peer timeout is still greater than this delay -- I also intend to redo test with normal conditions.) Is this a known/expected issue, which effectively means I shouldn't test using "ifdown ethX"? If so, is there some configuration I can apply to change behaviour to ifdown? My major fear is that some network failure could trigger the code path that leads to the isolated node updating CIB, etc. Thanks again, Tom -----Original Message----- From: Andrew Beekhof [mailto:and...@beekhof.net] Sent: 15 July 2013 01:52 To: The Pacemaker cluster resource manager Subject: Re: [Pacemaker] Issue with an isolated node overriding CIB after rejoining main cluster On 12/07/2013, at 10:49 PM, "Howley, Tom" <tom.how...@hp.com> wrote: > Hi, > > pacemaker:1.1.6-2ubuntu3, ouch > corosync:1.4.2-2, drbd8-utils 2:8.3.11-0ubuntu1 > > I have a three node setup, with two nodes running DRBD, resource-level > fencing enabled ('resource-and-stonith') and obviously stonith configured for > each node.
