So looking for commentary and wanting to demo pretty soon. The following
things I wanted to highlight/get feedback on:
-All node related configuration is not hosted in a global configuration
space like 'site' or 'passwd'. Notably, 'consoleondemand' becomes node by
node configuration (though it won't be called that, more on that below).
-To provide the simplicity that site/passwd provided, every single node is
considered a member of the 'everything' group unless some action is made to
undo that (explicitly deleting the group or explicitly removing a node from
it). I figure this allows the convention of people using 'all' as a
curated list of nodes considered to be really nodes contrary to the xCAT
philosophy of 'everything is a node' (and the group name matches).
-Providing more granularity in log configuration. I currently am
considering the following values:
full: continuously stay connected and log everything
events: continuously stay connected, log detected events (e.g. kernel
panic) and all data while someone is connected
interactive: connect only when a user wants a session, log all data
during that time
none: connect only when a user wants a session, write no data to log
at all
Technically, this could be broken out to two settings on when to connect
and what to log, but I think it's a bit easier to think of it in this way
and I don't think the options that would open up would be that useful
(connecting all the time, but doing nothing with that connection unless a
user is on, and logging events, but only when someone is watching).
So putting it together:
tabch key=consoleondemand site.value=1
Becomes:
nodegroupconfig everything console.logging=interactive
Also, I've been tentatively calling it 'confluent' (I like it suggesting
both being fluent in console management and the concept of the whole word
meaning flowing together), but I maybe that wouldn't fly since so many
things like to use that name, many of them in the IT space that could be
confusing. I don't know any software named 'confluent' (but confluence is
close). So any thoughts on what I should ultimately name it would be
welcome.
