What are you saying me ? I should have another communication

You need at least 2 connections between the nodes. It never was
different.
It once was true that a null modem oder serial cable as the second
connection was enough - from my _personal_ experience, having 2
ethernet connections is better (because faster and able to cope with
the rather high traffic of v2 (pacemaker)).
I tested two options. I think the best option is a second ethernet
card. I have configured this option but I saw that my cluster didn't
do a failover.
The two connections are in different networks (One in 192.168.18.X
and other in 172.16.1.0) but I don't know why pingd isn't going down
all of resources.
I have this connectivity constraint:
<rsc_location id="mail-connectivity" rsc="Mail-drbd">
<rule id="mail-pingd-prefer-rule" score="-INFINITY"
role="Master">
<expression id="mail-pingd-prefer"
attribute="pingd" operation="lt" value="1000"/>
</rule>
</rsc_location>
<rsc_location id="samba-connectivity" rsc="Samba-drbd">
<rule id="samba-pingd-exclude-rule" score="-INFINITY" >
<expression id="samba-pingd-exclude"
attribute="pingd" operation="lt" value="1000"/>
</rule>
</rsc_location>
And this colocation:
<rsc_colocation id="mail_drbrd_rule" rsc="Mail" with-rsc="Mail-drbd"
with-rsc-role="Master" score="INFINITY"/>
<rsc_colocation id="samba_drbrd_rule" rsc="Samba"
with-rsc="Samba-drbd" with-rsc-role="Master" score="INFINITY"/>
The node lost connectivity with 192.168.18.0 (I defined all host in
this network for pingd) and pingd value should be less than 1000.
Should be or is?
It Should be changing value but it isn't changing it.
(To know I am using: watch -n1 "cibadmin -Ql | grep status-.*-pingd" )
Pingd is writing this to log;
pingd[3181]: 2008/11/20_17:17:42 info: ping_read: Retrying...
Could you post your xml including the status section in this situation?
Yes, first I will compile the new version of Pacemaker because pingd was
broken in other versions and this could be the same.

Dominik
