I used ISPConfig to create a BIND DNS cluster, and it works great, but most here would consider that overkill.
most people except me (I have 9 DNS servers in 8 countries on 5 continents from 8 different providers) :P
The only option I know of is PowerDNS. Any others?
PowerDNS is a better choice for LEB's than bind9.
PowerDNS with PowerAdmin.

The instructions at the SolusVM wiki are pretty straightforward regarding how to setup a clustered PowerDNS setup:
http://docs.solusvm.com/powerdns
Simply add PowerAdmin on top, and you're good to go!

Thanks for the mention
@DomainBop - wow nice, I actually meant that most might think that using ISPConfig to manage the DNS cluster might be overkill.
I use PowerDNS to do this, a 32MB VPS is just more than enough for a pdns process, and you can use offload MySQL on other server but expect a little more responding time.
nsd is better
I mean, PowerDNS isn't bad, but if you take the MySQL backend into account it certainly takes more RAM than nsd.
@MikHo - Any possible issues with using Ubuntu 12.04 (which gives pdns-server 3.0-1.1ubuntu1 vs 2.9 with Debian Squeeze) instead of Debian with your PowerDNS guide?
@twain
Since ubuntu and debian are so close the steps should be the same.
Since it's mysql as backend and there is no difference regardless of the os.
The only thing that I can think of from the top of my head is the web-interface could be setup differently. Depending on httpd of choice.
But in general, the guide should work on ubuntu aswell.
@MikHo- Great thanks! Will be setting up a 2-server physical cluster today..
Powerdns is really simple to setup!
@twain
Good luck!
Let me know how it works out.
Webmin works as well
I'm a fan of nsd3 and a quick notify/restart script.
