Different search path/nameservers in master/slave cobbler servers

[Gonzalo Servat]

Hi All,

I have 2 cobbler servers in different data centres. The second cobbler
server is set to replicate all from the first. In the second data centre,
for every profile I'd like to set a different set of nameservers and search
path. If I change the path, when it replicates to the slave, it will change
it to whatever the primary is set to.

One solution is to edit my cron so that after a replicate, it sets every
profile to the nameservers/search paths that I want. Any other solution
come to mind?

Thanks!
Gonzalo

So we have 4 data centers.  Each data center has a different set of
name servers and search paths.  We deal with that by setting the
default_name_servers and default_search_path (or whatever it is) in
/etc/cobbler/settings at each site to the settings for that site and
then making sure that all profiles are empty in those settings, thus
everything gets the site specific details.

If you want each profile on the slave to have different options but
still inherit the profiles from the master, I've nothing but to say
your cron job is definitely one method.

Alternatively I guess you could re-write the networking snippet to
support drawing that data from an alternate source instead of the
name_server variables.  Then its an active process rather than a cron
job updating things.  Although is kinda meh to have to do it that way.

Ah, yes. I assume you then modified the post_install_network_config snippet
to use these variables to set the search path and nameservers?

Thanks for your reply.

No,  i dont believe that I did have to modify the snippet.
