Hello,
I have a problem with a new, small IPv6 reverse zone
It's a small zone, configured like this :
zone:
- domain: "a.8.1.a.8.0.0.0.0.d.1.4.1.0.0.2.ip6.arpa."
file: "a.8.1.a.8.0.0.0.0.d.1.4.1.0.0.2.ip6.arpa"
notify: "corrin"
acl: "acl_corrin"
dnssec-signing: "off"
module: mod-synthrecord/revovh2
There is data in the journal :
root@arrakeen:/var/lib/knot/external# knotc zone-read
a.8.1.a.8.0.0.0.0.d.1.4.1.0.0.2.ip6.arpa

3600 PTR corrin.geekwu.org.
But if I change anything (like adding another host), on knotc reload I
get this error :
knotd[21892]: error: [a.8.1.a.8.0.0.0.0.d.1.4.1.0.0.2.ip6.arpa.] zone
event 'load' failed (malformed data)
I've purged the zone with zone-purge, replaced the zone file with a copy
of the dump, and got a new record on reload, but further edits fails the
same way
I'm using knot 2.9.2-1~cz.nic~buster1 for deb.knot-dns.cz/knot-latest
Do you have an idea on what's going on ?
Thanks,

Hello Bastien,
Could you share the zone file and its exact modification?

Hello Bastien,
Could you share the zone file and its exact modification?

Hello.
(Your mail was lost in migration, so it will probably break the thread.)
I've attached zone.dump.txt, which is the zone file that were dumped by
knot after a shutdown; and zone.bad.txt, which was the modified file
I've edited and knot refuses to load
Regards,

Hi Bastien,
at my place, all your zone files tend to load normally.
Maybe the "malformed" something comes from another place than a zone file.
Could you please share some longer snippet of your logs?
Have you tried to purge the journal (if it makes no harm in your use-case)?

Hello,
Here is the complete log of the reload event.
(I do not get messages from the list, was my address blacklisted due to
errors, or is the delivery failing due to old records in DNS ?)
I purged the journal with
"knotc zone-purge a.8.1.a.8.0.0.0.0.d.1.4.1.0.0.2.ip6.arpa", is it a
better/stronger way ?
Thanks,

Bastien,
The zone purge operation requires the force mode:
"knotc -f zone-purge a.8.1.a.8.0.0.0.0.d.1.4.1.0.0.2.ip6.arpa"
Does this help?

I indeed used the -f flag, as instructed by knotc.
This allowed me to add the last 2 entries in the zone, but the problem
reappeared soon after that.

Ok,
Then try removing the journal directory.
Btw, is the same after server restart?

Removing the journal directory allowed me to make a bunch of changes.
The server was restarted a few times during the problem. That's why I
got my zone file overwritten by the dump ^^
I kept the journal directory in my /tmp, if you want to look at it. If
not, no problem ;)

If you could send us a tarball including journal, config file, and zone file it would be
nice :-)

Hi Bastien,
thank you very much for all the reports, information and data.
I hope i have found and fixed the issue.
The issue can be workarounded by deleting the whole journal (rm -rf
/path/to/journal/), if this makes no collateral damage.
It will be fixed by this patch:
https://gitlab.labs.nic.cz/knot/knot-dns/merge_requests/1104
You might check and verify my conclusions.
Thanks,
Libor

Hello.
I deleted my journal yesterday, so I didn't have a test case anymore ;)
Thanks for your work.
