Re: [cobalt-users] Setting a Seconday DNS Server - Help Please

["multivex RAQ" <johnny@xxxxxxxxxxxx>]

Dear Jeff:
                Thank you for your answer.

Maybe I will re-establish what I am trying to do:

I want to prevent downtime in the case of a hard disk failure in my RAQ or
in case DNS problems arise.
I understand I can use a RAQ4r with RAID, but both would be in the same
location, so this does not seem to be a good solution in case something
happens with that entire network..

I have two RAQs, each on a different location. I would like to use the
second to mirror the first, having both actualized content. So in case one
fails, being the other the secondary DNS for the domain, it could take over
and continue serving.

How would you establish such a solution?.

By the way, something I do not have clear (or may be I am totally wrong, in
this case please help me to clarify):

I understad that Secondary DNS takes the content from the Primary DNS Server
Disk instead as from the secondary DNS Server Disk. What happens if hard
disk in primary fails? From where will secondary DNS take content?

Regards

Johnny
