Error Reading DNS Settings

Hey folks, I'm having some odd problems with DNS. Over the weekend I added a second ML server to my network. I changed the hostname on my original server from my FQDN to server1.domain.com.

When I changed the hostname, the server created a new zone with a nameserver and machine record. I deleted those and added the proper information to my domain.com zone. I setup a secondary zone on my second server and everything was peachy. Now today I went in to change a CNAME record and DNS is all hosed up. In console it says it cannot load the zone file from db.domain.com.

I'm getting these errors:

Jul 10 20:38:27 server1.domain.com servermgrd[4118]: -[DNSManagerRRMgr bindZoneDB]: Unable to load zone database (RRs) for "domain.com" from file "db.domain.com": CNAME and other data

Jul 10 20:38:27 server1.domain.com Server[3758]: Error: The server '127.0.0.1' reported an error while processing a command of type: 'readSettings' in plug-in: 'servermgr_dns'. Error: Error Domain=XSActionErrorDomain Code=1000 "An unknown error occurred" UserInfo=0x7fad23a24c90 {NSLocalizedDescription=An unknown error occurred}

So it would appear that I entered something wrong but when I open my db.domain.com file in /var/named it looks fine.

Any thoughts?

Fixed it. There was indeed a rouge CNAME entry at the top of the db.domain.com file. Deleted that, restarted server.app and it works like a champ.

Hi Mplsee08, just a heads up to you and others that this also rectified this symptom on a clients OS X Server V.4 just recently.

I had what seems a corrupt db.domain.name file in /library/server/named

for this reading, I did the following

stopped the DNS on that server where the Server.app was seeing correct settings
renamed (in my case three primary zones)

warwick$ ls -1 /library/server/named

db.1.0.10.in-addr.arpa

db.2.0.10.in-addr.arpa

db.mydomain01.production

db.mydomain02.studio

db.myredirect03.com

localhost.zone

named.ca

named.conf

named.local

rndc.key

zzz_db.mydomain01.production

zzzz_db.mydomain02.studio

zzzz_db.myredirect03.com

start the DNS and reviewed the UI where all reserve DNS records were now available
stopped DNS, rename each of the 3 primary zone back to original, each time starting the DNS until I could see which one was corrupt.
manually added those Machine Records back for that zone using the Server.app/DNS UI

Thanks for your info it was very helpful.
