Preparations for scaling out - defaulting

 

Hi all,

There are some things coming up that will start to affect how we move forward 
with features and trying to keep them scalable.

The most interesting one of these for me at the moment is doing sensible 
defaulting on enlisted nodes, to reduce (or eliminate) manual input.  At the 
moment, admins have to set the parameters on each enlisted node one by one.  
This is going to get rather painful when setting up power parameters, for 
example.

I've suggested to a few people that we start having profiles like Cobbler does 
and apply them to nodes as defaults.  When we start having node groups (node 
groups are a set of nodes that need to share the same provisioning server, 
e.g. ones on the same subnet) those groups could have a default profile.  That 
would result in all nodes in a group getting a common default setting, which 
should hopefully work because they are all in the same subnet.

Does anyone have any comments on this approach?

Thanks.
