They are all different things, and should all be there for a
working system:

  codasrv:  The Coda file server, must be running on server(s).  It was
            used to be named "srv".

  auth2:    The authentication server, must be running on an authentication
            server(s) (could be the same machine(s) as any server(s)).

  update:   Actually, I think you mean updateclnt and updatesrv
            (and don't confuse with the "update" program use by the
            Linux OS).

            They are the programs use to make sure non-SCM server get
            the same database files (such as VSGDB, VLDB etc) as the
            SCM server.  In other words, when you make change to those
            database files on a SCM, sooner or later they will be get
            propagated to all other non-SCM server.  "updateclnt" should
            always run on non-SCM server, and "updatesrv" should always
            run on SCM machine.

            Umm..., it used to be the case that there is another
            program called "updatemon" which monitors and makes sure that
            updateclnt and updatesrv are always up and running.  Has it
            been retired ? I couldn't find it in recent Coda release
            (mines is 4.6.1).

  coda.o:   The kernel module that must be up and running in any
            Coda client.  However, usually, you don't need to start it
            explicitly, it will automatically loaded when you start venus.

On my system, I can check if all those babies are there by:
