is pingd doing alive tests differently compared to the normal ping command?
normal & flood ping of these hosts show 0% packet lost from my both nodes.
In the log below pingd - besides the warnings -
states that the node is alive and that it had sent an update,
but it does not show up in the cib.

I defined a constraint for a resource so that it depends on
pingd-internal
<constraints>
<rsc_location id="hbtest1b-connectivity" rsc="hbtest1b">
<rule id="hbtest1b-connectivity-exclude-rule" score="-INFINITY" >
<expression id="hbtest1b-connectivity-exclude"
attribute="pingd-internal" operation="not_defined"/>
</rule>
</rsc_location>
</constraints>
But this causes the resource to be unrunnable on either of my both
nodes,
There are as expected 2 pingd daemons running:
root 6132 1 0 21:07 ? 00:00:00
/usr/lib/heartbeat/pingd
-D -p /var/run/heartbeat/rsctmp/pingd-pingd-internal:0 -a
pingd-internal
-d 5s -m 1000 -h 172.17.32.23 -h 192.168.132.23
root 13142 1 0 21:47 ? 00:00:00
/usr/lib/heartbeat/pingd
-D -p /var/run/heartbeat/rsctmp/pingd-pingd-external:0 -a
pingd-external
-d 5s -m 1000 -h 195.244.97.241
The problem is, I can't see in the cibadmin -Q output that the pingd
daemons have
have stored their results anywhere..
In the log I see the following output:

Where should the current pingd status be located in the cib ?
What is wrong with my setup ?
