[Linux-cluster] having problems trying to setup a two node cluster

[Jonathan E Brassow]

try to do a 'ccs_test connect' after doing the cman_tool join, and see 
what happens

ccs_test will not allow you to connect to an inquorate cluster, unless 
you use the force option.  Since your nodes become quorate after 
cman_tool join, you should be able to connect...  If you can not, it 
suggests that the magma-plugins are not installed/correct.
