hello,
ill try to keep things short so please do not consider it rude:
2 (debian 4.0) nodes: eth0 = external; eth1 = hb channel
the cluster has been in the state:
Current DC: webcluster02 (917954cd-0285-4fcd-9cd2-671736c4de66)
2 Nodes configured.
> ...
Node: webcluster01 (49e81295-8e2f-4aeb-98f3-a14de6f62298): online
Node: webcluster02 (917954cd-0285-4fcd-9cd2-671736c4de66): online
on webcluster01 i issued /etc/init.d/networking restart causing:
Sep 26 10:33:59 webcluster01 kernel: [78706.462355] tg3: eth1: Link is down.
Sep 26 10:34:02 webcluster01 kernel: [78708.758368] tg3: eth1: Link is up at

Sep 26 10:34:29 webcluster01 heartbeat: [31919]: info: Link webcluster02:eth1
dead.

now, crm_mon is in a split-brain situation:
webcluster01:

Q: how do i resolve this issue without restarting heartbeat? shouldn't
there be a check to avoid this kind of split-brain situation?
do you need any further information?
cheers,
raoul bhatia
ps: i do not use stonith yet as i do not want stonith to interfere with
configuration errors :)
