DNS Clustering - Duplicate Entries in named.conf

[MattF]

I am having trouble with DNS clustering between 3 servers (2 of which are name server too), entries are getting duplicated in named.conf which of courses causes named to fail.

Funny thing... I have the same problem, but it not just duplicates one account it triples it. It only happens to one domain. Very strange.

That won't fix your problem will give you some ideas of to why things get whacked with dns clustering.

I made some perl scripts to do my own dns clustering works this way.
I kind of do it like in that post above but it isn't automatic.
I just use a cron to update the dns every few hours.

I have 3 servers in the cluster syncing each other ns1, ns2, ns3.
Now and then, when adding a new zone, i get duplicate entries in named.conf only on the server which runs ns3....

Having the same problems with 3 clustered servers.

How do you have them syncing?
Option 1
ns1 to ns2 and ns3
ns2 to ns1 and ns3
ns3 to ns1 and ns2

or
Option 2
ns1 to ns2
ns2 to ns1 and ns3
ns3 to ns2

I set my like option 1 above and sometimes get the duplicate problems. I was thinking about moving to option 2. It should have the same effect - IF ns2 will relay between the other 2.
