[Pacemaker] Active / Active pacemaker configuration advice

[Marko Potocnik]

Hi,



I am trying to configure a service (ftp for proof of concept) to run in an
active / active configuration. A floating IP is used to access this service.
What I am trying to achieve is that a floating IP would move to second node,
if service fails on the first node. After that service should be restarted.

I am able to achieve all but the restart of the service with the following
configuration:



node $id="34d5eba9-130f-4c64-9460-4a5310ac510c" jesenice.iskratel.si \

        attributes standby="off"

node $id="5fdf23a5-61c4-4a57-80fb-c764954a5f14" olimpija.iskratel.si \

        attributes standby="off"

*primitive res_ftp lsb:vsftpd \*

*        meta migration-threshold="1" \*

*        op monitor on-fail="restart" interval="10s"*

*primitive res_ip_ftp ocf:heartbeat:IPaddr2 \*

*        params ip="172.18.251.6" cidr_netmask="24" \*

*        op monitor interval="15s" timeout="30s"*

*clone c_ftp res_ftp \*

*        meta clone-max="2" clone-node-max="1" globally-unique="false"
target-role="Started"*

*colocation c_ip_on_ftp inf: res_ip_ftp c_ftp*

property $id="cib-bootstrap-options" \

        dc-version="1.0.8-9881a7350d6182bae9e8e557cf20a3cc5dac3ee7" \

        cluster-infrastructure="Heartbeat" \

        stonith-enabled="false" \

        default-resource-stickiness="200" \

        no-quorum-policy="ignore" \

        last-lrm-refresh="1290440895"



If I up the migration-threshold then service restarts n times, but floating
IP doesn’t move to another node. Do you have any idea how to achieve the
desired configuration?



Regards,


Marko
