Hi,
I've been using RHCS for a while but for a couple of projects I need to
evaluate some other solutions.
I download/installed and configured (for what I could understand)
heartbeat but I'm haveing some problems.
Thank in advance for help.
Goal is to have a two cluster node with an active/passive apache2
configuration.
The setup is two nodes with Ubuntu 7.04 with (ConfigureME
configure/make/install) hearbeat 2.1.3.
Ubuntu01 eth0 192.168.43.161
Ubuntu02 eth0 192.168.43.112
Both nodes have eth0:0 configured at 192.168.42.185
The problem is I can't manage to let this work, after a couple of
seconds crm_mon gives:
Refresh in 2s...

Node: ubuntu01 (29e45e42-476f-4fff-ae68-866c06815b3f): OFFLINE
and after some more time it prints:

IPaddr_192_168_42_185_start_0 (node=ubuntu02, call=5, rc=1): Error
I hope I made myself clear enough, configuration files follow.
Here is the very simple ha.cf:
use_logd yes
ping 192.168.42.254
bcast eth0
auto_failback off
node ubuntu01 ubuntu02
crm on
I created the cib.xml for each node converting a very easy haresources
file (ubuntu01 192.168.42.185/24/eth0:0 apache2) with the appropriate
python script; here is the cib.xml for the node ubuntu01:
<cib admin_epoch="0" epoch="1" have_quorum="true" ignore_dtd="false"
num_peers="2" ccm_transition="2" cib_feature_revision="2.0"
