    Yes.

    

    P.S. Dont remove the mailing list from the recipients. Bad etiquette
    :-)

            That document says
              to remove the pacemaker plugin.  Should I start pacemaker
              as a service?

                   Yes, the original documentation you came across
                    that talks about CMAN :-)

                    http://www.clusterlabs.org/doc/en-US/Pacemaker/1.1/html/Clusters_from_Scratch/ch08s02.html

                    Though you dont need the gfs stuff if youre not
                    going to be using gfs

                            Is
                              there some documentation on how to set up
                              option 3?

                              

                              corosync + cpg + cman + mcp

                              

                              Do I simply start up pacemaker????

                              Also, what is cpg?

                                            I've spent
                                              the last month or so
                                              building linux clusters. 
                                              2 of them in a VM
                                              environment on fedora 15. 
                                              I went through the
                                              Clusters from Scratch
                                              Tutorial; which sort of
                                              worked.  At this time I am
                                              looking for a sanity
                                              check.

                                              

                                              My requirements are  to
                                              have  a 4 node load
                                              balanced cluster with
                                              shard access to a SAN
                                              volume.  The SAN will be
                                              using GFS2.

                                              

                                               I believe I need
                                              corosync, Openais,
                                              PaceMaker, and GFS2
                                              utilities.  

                                              

                                              Where the confusion is
                                              coming from is the use of
                                              CMAN in the clusters from
                                              scratch.  It seems from
                                              what I am reading that
                                              Pacemaker should be able
                                              to do everything I need
                                              and I am wondering if the
                                              use of cman is old
                                              information.  

                                              

                                              Any thoughts comments or
                                              suggestiosn are greatly
                                              appreciated, Thanks in

                                    No, CMAN is the new information.
                                    Theres a nasty bug out there (see http://www.mail-archive.com/openais@lists.linux-foundation.org/msg05600.html)
                                    if you setup pacemaker 1.1 without
                                    the new MCP stuff. Best solution is
                                    to switch to CMAN.
