I changed the location line so that now I have:
primitive pinggw ocf:pacemaker:ping \
params host_list="192.168.101.1" multiplier="100" \
op start interval="0" timeout="90" \
op stop interval="0" timeout="100"
clone cl-pinggw pinggw \
meta globally-unique="false"
location nfs-group-with-pinggw nfs-group \
rule $id="nfs-group-with-pinggw-rule" -inf: not_defined pingd or pingd lte 0
But now nothing happens if I run for example
iptables -A OUTPUT -p icmp -d 192.168.101.1 -j REJECT (or DROP)
in the node where nfs-group is running.....
Do I have to name the primitive itself to pingd????
It seems that the binary /bin/ping is not accessed at all (with ls -lu ...)
Or do I have to change the general property I previously define to avoide
failback:
rsc_defaults $id="rsc-options" \
resource-stickiness="100"
crm_mon -f -r gives:
Online: [ ha1 ha2 ]
Full list of resources:
SitoWeb (ocf::heartbeat:apache): Started ha1
Master/Slave Set: NfsData
Masters: [ ha1 ]
Slaves: [ ha2 ]
Resource Group: nfs-group
ClusterIP (ocf::heartbeat:IPaddr2): Started ha1
lv_drbd0 (ocf::heartbeat:LVM): Started ha1
NfsFS (ocf::heartbeat:Filesystem): Started ha1
nfssrv (ocf::heartbeat:nfsserver): Started ha1
nfsclient (ocf::heartbeat:Filesystem): Started ha2
Clone Set: cl-pinggw
Started: [ ha2 ha1 ]
Migration summary:
* Node ha1: pingd=100
* Node ha2: pingd=100
Probably I didn't understand correctly what described at the link:
http://www.clusterlabs.org/wiki/Pingd_with_resources_on_different_networks
or it is outdated now... and instead of defining two clones it is better
(aka works) to populate the host_list parameter as described here in case of
more networks connected:
http://www.clusterlabs.org/doc/en-US/Pacemaker/1.1/html/Pacemaker_Explained/ch09s03s03.html
Probably I'm missing something very simple but I don't get a clue to it...
