[Openais] first time install of corosync, openais and pacemaker on ubuntu 9.04

[Frank DiMeo]

Yes, the pacemaker.lcrso file is in the correct place.

Here's the current status:

1) I was confused as to which configuration file to use when using both corosync and openais together.  I thought that the /etc/ais/openais/openais.conf file would override the /etc/corosync/corosync.conf file, but it seems that it's the other way around.  Even when you use /etc/init.d/openais to start, the /etc/corosync/corosync.conf file is used.

2) The /etc/init.d/openais script calls out openaisserviceenable, but the code (openais 1.1.2) is built to load something called openaisserviceenablestable.  When I change the /etc/init.d/openais to call out openaissserviceenable, then it loads that module correctly.  Maybe I have an old or outdated /etc/init.d/openais??

3) The /etc/init.d/openais script calls out openaisparser, but I don't find any registration for that module in the code, so it fails to start.  Also, there is no openaisparser.lcscro file.

4) If I remove the remove openasiparser from the /etc/init.d/openais script, then /etc/init.d/openais start fails and says: "couldn't find totem handle"

5) If I remove the references to both openaisserviceenablestable and openasiparser from /etc/init.d/openais, then everything starts normally, and pacemaker seems to load (according to /tmp/corosync.log
