Joe,
I saw a problem in the rc.lvs_dr script for running on the real servers. I
changed these lines:
DIRECTOR_INSIDE_NETWORK="255.255.255.240"
DIRECTOR_INSIDE_NETMASK="209.116.71.47"
to:
DIRECTOR_INSIDE_NETWORK="209.116.71.32"
DIRECTOR_INSIDE_NETMASK="255.255.255.240"
It still isn't working, but at least the script output on the real servers
is a bit cleaner:
