Remove old DNS Local Data

[MtK]

Hey,
I have a server that was part of a multi-server cluster, where other servers updated it with their DNS data/zones, so the server if full with Local Data = NO zones.
I've recently moved the NS Server from within DirectAdmin to an external DirectSlave.

Is it safe to delete all those Local Data = NO zones?
won't they be deleted in other servers (by mistake)...?

It should be; the worst case is the zones will be deleted.

Isn't that what you want?

well, not really, since it will delete the data from the actual 'real' server as well.

Sorry, I missed that . What about just turning off the clustering to that server? Or have I missed something else?

It is safe to delete them if you switch off MultiServer function on the server prior to deleting, or you might want to remove them from named.conf file directly.

Thanks, I did just that.

nope, cause I can't tell from there which is local (which is still needed) and which is not.



speaking of which, is it now safe to disable named completely, on that server?

Are you hosting domains on this server? If so, are you hosting DNS elsewhere? If so, where are people updating their DNS? On this server?

If you're using Multi-Server on this server to host DNS elsewhere I believe it's done as multiple masters to other DirectAdmin servers, and if so, Multi-Server may work even with BIND off, but if you're using any slave solution it won't work because BIND must be on for the server to act as a hidden master.

if you're managing DNS on this server then you'll need to have some kind of stub do-nothing program where BIND should be, because DirectAdmin will try to restart BIND every time a change is made.

yes, yes, elsewhere (directslave).

directslave took care of it

My understanding is that DirectSlave uses Master->Slave function built into BIND to actually transfer the zones. If that's so, then BIND must be turned on at the master, even if it's a hidden master.
