Hello,
i'm trying to configure a 2-node cluster with one resource (ClusterIP) which
should only be allowed to run if a cloned ping resource succeeds.
After reading the pacemaker configuration explained document and some WIKI
entries i came up with the following configuration:
node centos5srv1
node centos5srv2
primitive ClusterIP ocf:heartbeat:IPaddr2 \
meta target-role="started" is-managed="true" \
operations $id="ClusterIP-operations" \
op monitor interval="1s" timeout="5s" start-delay="0" \
params ip="192.168.0.65" cidr_netmask="32" nic="eth0"
primitive ping ocf:pacemaker:ping \
params dampen="5s" multiplier="1000" host_list="192.168.0.60
10.100.64.50" name="pingval" \
operations $id="ping-operations" \
op monitor interval="10s" timeout="5s"
clone Connected ping
location ClusterIP_on_Connected ClusterIP \
rule $id="ClusterIP_on_Connected-rule" -inf: pingval lt 2000
property $id="cib-bootstrap-options" \
dc-version="1.0.7-d3fa20fc76c7947d6de66db7e52526dc6bd7d782" \
cluster-infrastructure="openais" \
expected-quorum-votes="2" \
no-quorum-policy="ignore" \
stonith-enabled="false"
rsc_defaults $id="rsc_defaults-options" \
resource-stickiness="100"
but this does not work, the ClusterIP resource wont get started at all.
after i removed all but one ping-target from the configuration, (and the
constraint accordingly) it works.
primitive ping ocf:pacemaker:ping \
params dampen="5s" multiplier="1000" host_list="192.168.0.60"
name="pingval" \
operations $id="ping-operations" \
op monitor interval="10s" timeout="5s"
clone Connected ping
location ClusterIP_on_Connected ClusterIP \
rule $id="ClusterIP_on_Connected-rule" -inf: pingval lt 1000
as i understand the documentation i am allowed to put multiple targets into the
"host_list" directive, and the value of "pingval" contains the number of
reached hosts multiplied with the value of "multiplier"?
in the log i see errors complaining about a failing ping:
Jan 26 15:42:15 centos5srv2 lrmd: [21076]: WARN: ping:0:monitor process (PID
885) timed out (try 1). Killing with signal SIGTERM (15).

-q -W 5 -c 5 10.100.64.50' 143:
when i issue the stated ping cmd "ping -n -q -W 5 -c 5 10.100.64.50" myself,
it succeeds.
i probably could create a cloned ping resource for every host i want to have
checked and than write corresponding rules for the location constraint, but
this would result in a much more complex configuration that is needed as far as
i understood the docs.
Any Help/Suggestions are appreciated :-)
Using:
centos5.4 x86_64
corosync-1.2.0-1.el5
openais-1.1.0-1.el5
pacemaker-1.0.7-2.el5
Thanks & Regards,
Moritz
