[Pacemaker] Linux HA setup for CentOS 6.5

[Digimer]

You can manually configure the wireless LAN without NetworkManager. If 
you take a look, there should be existing config files in 
/etc/sysconfig/network-scripts/ for the wireless connection. I've not 
done it myself since many Fedora's ago, but I believe you can change 
NMCONTROLLER="no" and then start it up with /etc/sysconfig/network 
start. I could be a bit wrong, but I am sure you can make wireless work 
without NM.

Question; Servers with WLAN? I assume these won't be used for corosync?
