Sorry, somehow I missed this question ...
The intent is to avoid sending notifications to *all* clients. The
cluster user mode scripts will have to associate the floating IP(s) with
fsid(s) and relies heavily on the information passed by rpc.statd's
ha-callout program. My test ha-callout user mode program shows the
following:
/mnt/lockd/ha-pg/hatest is invoked with 3 arguments.
add-client
192.168.24.146
192.168.24.149
/mnt/lockd/ha-pg/hatest is invoked with 3 arguments.
del-client
192.168.24.145
192.168.24.149
These info(s) will be used to construct the notification list when
notification actually take places.
