Good afternoon,
in preparation for Knot 3.1, I wanted to update our template that uses
zonefile-load: difference-no-serial from journal-content: changes to
journal-content: all.
However, it seems that we somehow have to update the existing journal.
Otherwise it seems the first change to a zone after that change, will
lead to the following error (running knot 3.0.4):
error: [example.net.] zone event 'load' failed (semantic check)
Subsequent changes seem to be applied just fine.
What is the proposed strategy to change this setting?
Regards
André

Hello André,
thank you very much for your report.
However, I found rather little information. Could you please provide
some more info about you configuration (at least zonefile-sync and
zonefile-load) and longer log snippets uncovering what was going on
after the configuration change?
Thanks,
Libor

I'm afraid the log is not much more verbose, I can try to reproduce the
issue with a higher log level if that would help.
So after the config change:

Then when adding a record to the zonefile:

But me initial statement, that subsequent changes work was wrong. The
zone that loaded, was the original zone. If I now make changes to the
zone it always fail to load, if I revert the zone-file to the original
state and reload, the changes go through. So currently with the new
journat-content: all setting, I cannot make changes to this zone.
(And the change is syntactically correct, zone-check and named-checkzone
do not have any issue with the new zonefile)
Configuration (knotd (Knot DNS), version 3.0.4):
server:
user: knot:knot

@ IN AAAA 2001:db8::100
www IN A 192.0.2.100
www IN AAAA 2001:db8::1010
I omitted the acl/remote/key section as well as the definition of the
other zones, as I do not think this is relevant information for the
issue at hand. Please let me know if you need this information.
-> journal-content: allin the master_dnssec template is the only change
I did. There was no journal-content configuration before. There are
other zones using this template that show the same behavior, zones using
using the master_default template work normally.
Does this information suffice or would you need to know anything else?

Hi André,
thank you for your report and the detailed information you provided.
I was able to reproduce your issue and it occurs to be a bug. We will
fix it for the next 3.0.x version.
You might use any of two possible workarounds:
1) after changing the configuration file by setting journal-content:
all, you can stop and cold-start knotd instead of reloading the
configuration.
2) before changing the configuration, you can stop the single affected
zone by `knotc -f purge +expire example.net.` and proceed with `knotc
reload`.
Cheers,
Libor
