Linux Bind dns delegation
an you please give me a little assistance with how to properly Delegate the DNS record for the isilon smart pool via Linux DNS bind 9.
Currently I have the following configured
Isilon smart pool name: isilon.nfs.hpc.work
$ORIGIN .
- nfs.hpc.work NS isilon.nfs.hpc.work
$ORIGIN hpc.work.
- Isilon.nfs A 192.168.10.245
After restarting named (service named restart) I am not able to accomplish any of the following from the delegating DNS server:
Dig –t any nfs.hpc.work (no records returned resolved)
Dig –t a isilon.nfs.hpc.work (no records returned resolved)
Yet I get expected results when I query the isilon
Dig –t a +norecurs –t any nfs.hpc.work (query is properly answered with above configured NS & A record)
Dig –t any +norecurse isilon.nfs.hpc.work (Query is properly answered with above configured A record)
Dig @192.168.10.245 –t any nfs.hpc.work (no records returned)
Dig @192.168.10.245 –t a isilon.nfs.hpc.work (query properly resolved in a round robin manor)
Thus I am slightly confused as to my knowledge both sides are properly configured yet clients are unable to resolve the isilon.nfs.hpc.work record.
Any assistance will be greatly appreciated.
Thank you

Hi Chjatwork,
I suppose you want to create a Linux Bind DNS setup for use with smartconnect, not use with smartpools. Because Smartpools software is used for optimizing your scale-out storage resources with automated storage tiering. Is it right?

For example, the two lines of text will look similar to:
sc-nfspool.company.com. IN A 10.7.149.100
nfspool.company.com. IN NS sc-nfspool.company.com.
from:
Isilon OneFS: How to create a UNIX-based BIND DNS setup for use with SmartConnect
Here, sc-nfspool is the name for the fixed IP of the Isilon SmartConnect Adv DNS server lives.
nfspool is the name to be used as server when mounting from the SC zone (for a given address "pool" ;-)

Jeffey,
Correct we need SmartConnect to help us to do load balance on this secondary network that Isilon is connected to. No need for SmartPools because we don't have but the NL-400s all with the same type of spinning disk in them.

I was wondering if someone was able to make this work. Using BIND version 9 and implementing the said configuration in https://support.emc.com/kb/89758
doesn't work.

Configuring BIND for Isilon seems to be very tricky - in our cases the problem was the forwarders weren't enable for that particular zone.
Depending on your BIND configuration, it may be necessary to add line like the following for the particular isilon zone:
forwarders {Service.IP.Of.Isilon;};
