I'm working on clustering my DHCP server on a 5-node OES11 SP1 cluster. I'm stuck on step 8 of the docs that says

Copy the /etc/dhcpd.conf file to /media/nss/DHCPVOL/etc directory and modify the LDAP attributes as required.
For example,
ldap-server "";
ldap-dhcp-server-cn "DHCP_acme";
Set the ldap ‐ server attribute with the shared NSS pool IP Address.
Set the ldap ‐ dhcp ‐ server ‐ cn attribute with the name of the DHCP server object that you want to use.

My problem is that if I use one of the five nodes, what's the point of clustering DHCP? If that node dies, DHCP is dead. What do I put there?
