Hi, So I've decided to make things simpler and go with a wired network instead of wireless. I connected both boxes to a router, manually edited the ifcfg-eth0 files to set static IP addresses for both boxes (not before downloading and building a driver for the nic of 1 of the boxes), did a "chkconfig NetworkManager off", "service NetworkManager stop", and "service network restart".
I'm able to ping each other via IP address and hostname. I also already have corosync, pacemaker, crmsh and cman installed. I then did the following as per the guide at http://geekpeek.net/linux-cluster-corosync-pacemaker service corosync start - success. service pacemaker start - I get a "Starting cman...corosync cluster engine is already running [FAILED]" What's up? :( On Oct 15, 2014 12:23 PM, "Sihan Goi" <gois...@gmail.com> wrote: > No typo. > > [root@node02 network-scripts]# ls -lah > /etc/sysconfig/network-scripts/ifcfg-* > -rw-r--r--. 1 root root 254 Oct 10 2013 > /etc/sysconfig/network-scripts/ifcfg-lo > > I installed CentOS 6.5 with the LiveDVD.
