Is it possible to make rndc always validate on reload?

Question

I've noticed that on some occasions, when I run rndc reload foobar.com, it'll validate the domain -- it'll give me an error if there is one, for example:

rndc: 'reload' failed: multiple RRs of singleton type

... or ...

rndc: 'reload' failed: not a valid number

... which is good.

However, some times, rndc will say:

rndc: zone reload queued

... and the error will only be logged.

Is it possible to have rndc always validate on reload? The reason being, when my application updates a zone, it runs rndc to reload the zone and assumes that it will fail if the zone is invalid. However, it only does this some times.

Try:

named-checkzone

To expand on that answer a bit: I'm not aware of a way, via rndc, to force an immediate reload. But by working named-checkzone into your reload operation, as with a small script or alias, you can accomplish your goal.

Yeah, I think I'll change the app so it calls this first. Thanks. – Nick Bolton Jul 07 '10 at 18:56

`named-checkconf -zj` may be helpful for a broader check (validates config + zones found from config). – Håkan Lindqvist Jun 26 '19 at 15:25
