Okay, as long as makedns -e updates the external named server just like it
would a local named instance. The reason I had asked that is because the
documentation was rather ambiguously worded on that point. So now I'm just
trying to figure out the best way to make xCAT only update the external DNS
instance. Since you said that you have the problem of the local deamon
starting up regardless when you run makedns -e, have you ever noticed
whether it is actually updating local records also? Is your /var/named/
directory on the xCAT server populated with zone files? Also did you remove
the MN's local host IP (whether loopback or assigned) from its
/etc/resolv.conf and make it point only to the external DNS server's IP?
Since I'm trying to transition without an outage I think I will have to
have a brief period where I have both the MN and the external server
running identical named configs. Then I can slowly begin to move my compute
cluster nodes to resolve to the external server in 10 node increments or
so, so that I can troubleshoot any problems and undo it to resolve back to
the MN again if need be. I just want to be as careful as possible.
Thanks,
Josh

What does it mean that you must manually configure the hostnames
and IP addresses? Does 'makedns -e' not do that for you, just like
it would if DNS were running locally on the MN itself by just
parsing /etc/hosts and adding/pushing it to the (remote) DNS zone
files for you?
We've occasionally pushed records into the DNS server by hand when
they're things external to xCAT, but I we've gone from that to
defining them in xCAT on our infrastructure management node and
pushing from there.
So we've got 4 xCAT management nodes updating the same external DNS
servers with makedns -e.
cheers,
Chris
