More specifically, whenever you run makedhcp -n on the mgmt node (which only has to be run if you change your networks table), you should edit your dhcpd.conf file on the mgmt node (and service nodes if you have them) and replace the line:
option domain-name "<domain1>" with option domain-search "<domain1>", "<domain2>" and restart dhcpd. This should cause dhcp to put both of these domains in the computes nodes' /etc/resolv.conf file every time it gets a dhcp lease. If you just sync /etc/resolv.conf from the mgmt node to the compute nodes, it will be overridden each time the dhcp client renews its lease, unless you set PEERDNS=no in the relevant /etc/sysconfig/network-scripts/ifcfg-* file.

For now, on the node's master and the node, if you run makedhcp, you should edit the dhcpd.conf file that is created and add your additional domain to search. If you just sync the /etc/resolv.conf file then each time dhcpd is restarted, it will overlay your sync'd file. Lissa K.
