[gpfsug-discuss] changing default configuration values

Hi Aaron,

The default value applies to all nodes in the cluster.  Thus changing it
will change all nodes in the cluster.  You need to run mmchconfig to
customize the node override again.

Is there a way to change the default value of a configuration option
without overriding any overrides in place?

Take the following situation:

- I set parameter foo=bar for all nodes (mmchconfig foo=bar)
- I set parameter foo to baz for a few nodes (mmchconfig foo=baz -N
n001,n002)

Is there a way to then set the default value of foo to qux without
changing the value of foo for nodes n001 and n002?

-Aaron
