Hi,
I had some problems with my subscription and e-mail, so I send my forst
mail again here:
I am using Heartbeat 2.0.8 on Fedora 7.
It's a two node cluster Activie/Passive with crm activated.
The cluster starts up fine, but if i block with iptables the ping nodes
on the active node, then it will not start the resources on the other node.
In the logs I see of the actove node:

This will give you a pingd score of 500. A ping_group is treated as one
ping_host score wise.
If you want to take each ping hosts connectivity into play, you should have
ping 10.14.0.10
ping 10.14.0.11
ping 10.14.0.12
ping 10.14.0.13
instead. This would give a pingd score of 2000 (and make your setup work
score-wise).

Apart from the fact that these attributes should be "meta_attributes"
instead of "instance_attributes", this will give you a score of 4 * 200
= 800 for the node the group is actually running on.
So with ping working, you should have scores of
800 + 500 for node1
500 for node2
Now you block icmp on node1. You will have:
800 on node1
500 on node2
So why should the cluster move any resource?

It would be nice to acutally get this setup working with scores, but it
does not work as you see in the logs. There won't be a failover to the
other node.
Any hints, how i could get working the setup with scores as above?
Thanks,
Achim

Hi,

to
<rsc_location id="group_1:connected"

<expression

value="0"/>
</rule>
</rsc_location>
Now it works as expected. Those two setups were described on:
http://www.linux-ha.org/pingd
But still it would be nice to get pingnodes working with scores as
made in my first example or described on taht page in "Quickstart -
Run my resource on the node with the best connectivity".
Does anyone have any hints how to get that stuff working?
That should work - what did you see (and what did you expect)? You
propably need to adjust the pingd multiplier. showscores.sh helps a
lot here to figure out what's not as expected (see
http://www.linux-ha.org/ScoreCalculation )
