Hi all,
While trying to test to answer questions from my previous thread, I
hit another problem. Since posting the first thread, I moved on in the
Cluster from Scratch tutorial and got to the point where I was running
Active/Active.
Here I have a couple of problems.
First up, the dlm service doesn't start with the cluster, but I can
start it successfully manually.
Second, and more annoying, I can't get the cloned apache service to
start on both nodes:

Any other thoughts?
I went over CfS again and this time I don't see the WebSite clone, so I
probably just screwed up while trying to follow along. I'm going to blow
away my config and start over. :)
Cheers!
