[drbd-mc] Possible to edit heartbeat settings after cluster setup.

[Caspar Smit]

Hi Rasto,

During the cluster setup wizard I get a configuration window with the
/etc/ha.d/ha.cf config file and that it should be equal on both sides
(naturally).

Is it possible to edit these heartbeat settings AFTER the cluster has been
setup? I can't seem to find it anywhere.

When I do a cluster setup of the existing nodes the selection between
heartbeat/corosync is greyed out (can't select anything)

Kind regards,

Caspar Smit

In the "Cluster Wizard", you can get to the config file dialog window and
press "edit a new config".

It is greyed out if Heartbeat or Corosync is not installed or both.

Normally you shouldn't change it after you configured one of them, and if
you do, you should clean up the hostnames on couple of places, because of
how host id changed in the configuration.
