[CentOS] BiND Failover

[Darrin Khan]

Hi,

If it is a mission critical system, check out http://www.linux-ha.org/

I have that managing a cluster of servers for HA SQL. In your case you may
get away with just using a floating IP. Have the DNS pointing to that.

Then no matter what server the IP is on the DNS doesn't need to be updated.
the fail over times in this type of setup are relativley low, maybe <1m
depending on how you set it up ..

Another Idea anyway.
