[Pacemaker] 2 node cluster enters deathmatch. Please Help!

I have a fairly simple two nodes cluster with one "lsb" resource and "external/ipmi" based "stonith"s
In attempt to test STONITH I did "#killall aisexec" on one of them and as expected it was immediately shot.
However when on reboot I started the cluster software again it shot the survived node and this "revenge" game seems to go for ever :-(.
I noticed that both nodes keep different version of the ring counter and was wondering if there is a command to tell a failed server that it has been dead for a while and should not pull the trigger but rather persist synchronizing.
Please, help!
Am I missing something in my cluster config? Is there a proper procedure to bring failed nodes back into the cluster?
P.S. here is my config:
node ppst1pru001
node ppst1pru01
primitive pprus lsb:pprus \
        op monitor interval= 10s  timeout= 90s  \
        op start interval= 0  timeout= 25s  \
        op stop interval= 0  timeout= 25s  \
        meta target-role= Started 
primitive ppst1pru001-stonith stonith:external/ipmi \
        params hostname= ppst1pru001  ipaddr=  userid= root  passwd= 1q2w3e$  interface= lan 
primitive ppst1pru01-stonith stonith:external/ipmi \
        params hostname= ppst1pru01  ipaddr=  userid= root  passwd= 1q2w3e$  interface= lan
