Good.

Not sure what you mean.

Please search the archives before posting.  This is discussed
almost monthly.

Quick summary:

* DNS is easy enough.  Let one server be the master, and all
  others be the slave.  You can do this on a per-domain basis.
* MX should be primary/secondary.
* Websites can get you into trouble with dynamic content and
  log processing.
* Forget about databases.

CobaltOS is NOT a distributed/cluster operating system.  Any sort
of redundancy is implemented on a per-service basis.  Searching
the archives will give you a good start... there's simply too
much to put in one email message, and the thread comes around
very often.

Most hardcore high-availability involves moderate amounts of
"roll your own" and/or coding... which is way beyond the scope of
this list. ;-)
