We're wanting to build a web server farm with approx 18 nodes. We're 
aware of scalability issues with Corosync/Pacemaker but we're also told 
that it is getting better with newer versions of the software. Ubuntu 
12.04 is packaged with corosync 1.4.2 and pacemaker 1.1.6.  I imagine 
that we'll probably need to remove the packages and compile from source 
to get the later versions.  What is the latest version suitable for 

Also, does anyone have any suggestion for tuning Corosync to scale to 
18-24 nodes, running 18 services?

Thanks for any help.
