Hi All,
I have a 2 node cluster. My intention is ensuring the VIP is always on the
node that has httpd running, i.e. if service httpd on the VIP node is
stopped and fails to start, the VIP should switch to the other node.
With the configuration below, I observed that when httpd stops and fails to
start, the VIP is stopped also but is not switched to the other node that
has healthy httpd. I appreciate any ideas.
