RE: Configuration of BIND (named) for GNS in 11.2 RAC

It's hard to say without testing it, but the issue could be that your bind server is configured to slave the from the gns-server IP, which does not yet exist (hasn't been bound to the machine). This will cause bind to attempt to contact that IP, fail to, and then start returning SERVFAIL to queries directed against that subdomain, since it hasn't been able to slave the zone (this is correct behavior, btw, since NXDOMAIN is a cacheable query response, and in this case the dns server is just saying, "hey, look, maybe it's me").

Try removing the prod-cluster search subdomain, and if that doesn't work, you can try reversing the nsswitch order.

You can also manually enter your gns-server ip in the hosts file, see if that fixes it.

Hello group,

I am trying to get my head around GNS but somehow I am unable to install
Grid Infrastructure for RAC. OUI complains about INS-40904, unable to
resolve the hostname I put in.

This is RHEL 5.4 32bit, bind and dhcpd are configured and running. I am
pretty sure that name resolution works as I can ping the hosts without
entries in /etc/hosts. /etc/resolve.conf and /etc/nsswitch.conf are as
follows, I have attached my bind configuration (the custom one) to the
email. I also used the advanced installation as explained in the
documentation section 2.7.3 DNS Configuration for Domain Delegation to
Grid Naming Service

More info:

[root_at_node1 OraInstall2009-09-28_08-48-53PM]# grep hosts /etc/nsswitch.conf
hosts: dns files Any pointers greatly appreciated. BTW there is nothing on google or metalink about the particular error.... The gns-server VIP is not assigned to a host (can't ping it). The DNS server host can't reach the Internet, bind occasionally complains about not being able to resolve "." zone (which I don't want it to) Regards, Martin --
