Well, if it works for other zones, it's unlikely to be an OS problem unless
that zone was built in the system using an older version that did things
slightly differently and now it can't be removed because of that difference.
Have you tried comparing a working zone that can be deleted from the problem
zone with rndc zonestatus and rndc showzone? Maybe something will stand out
there. But at this point, all I have to suggest is theoretical. Sorry, I
don't know how to manually remove / rebuild the zone database. If you're stuck
after this and no one has any further suggestions, I'd recommend turning up the
logging level on named and comparing operations or doing them under strace and
seeing where success and failure diverge.
Best of luck,
Scott

OS running is FreeBSD 12.1 with bind version 9.16.7.
I'm running rndc commands as root user.
Yes, the zone was created with rndc addzone. And it's also possible to add and
delete other zones this way.
Only the one particular zone throws this error.
Is there a way to manually clean or rebuild the nzd database?
Thanks, Christian

There are a LOT of possibilities why this isn't working. The first two things
I'd check is trying this action again as root (if you're not already) to make
sure this action isn't trying something that's DAC prohibited and checking the
SELinux / AppArmor log (if you're running them) to see if this particular
action (it doesn't sound like it's something you do often) is making a system
call that's forbidden by the MAC.
These are suggestions to see if the issue is at the OS level, of course. I'm
assuming what you're doing is permitted in the application (i.e. the zone
you're trying to delete was created with rndc addzone) but you haven't provided
enough detail to determine that.
HTH,
Scott

Subject: unable to delzone
Hi,
I want to delete a zone with:
rndc delzone domain.org
In the logfile I get:
Oct 12 10:16:30 nsmaster named[669]: general: received control channel command
'delzone domain.org'
Oct 12 10:16:30 nsmaster named[669]: general: zone domain.org scheduled for
removal via delzone
Oct 12 10:16:30 nsmaster named[669]: general: deleting zone domain.org in view
_default via delzone
Oct 12 10:16:30 nsmaster named[669]: general: mdb_txn_begin: Invalid argument
Oct 12 10:16:30 nsmaster named[669]: general: unable to open NZD database for
'_default.nzd'
Oct 12 10:16:30 nsmaster named[669]: general: unable to delete zone
configuration: failure
And so in the nzd db the config remains active:
named-nzd2nzf _default.nzd | grep domain.org
zone "domain.org" { type master; file "../dynamic/domain.org"; };
So why can the nzd db not be opened? And how can that be solved?
Thanks in advance,
Christian
