Answering to myself after I've been pointed out off-list that I was missing
lmdb-shards=1
in my pdns.conf
I don't know how I missed that, but as soon as I added that line,
lightningstream sync worked straight away and I can now see all changes
propagated in both directions - new zones, editing the content of a zone etc
Thank you Konrad! :-)
Cheers,

Hi,
I'm testing PDNS Auth 4.8-beta1 with lightningstream on FreeBSD 13.
I compiled PDNS manually with LMDB module (and gmake, as suggested in
the README), and am using Backblaze B2 as S3 backend.
The Lightningstream log indicate that replication happens in both
directions, and I can indeed see the snapshots in my S3 bucket.
But when I create a DNS zone on one PDNS server (with pdnsutil) and
populate it, I can't see that zone on the second PDNS server - a
pdnsutil list-all-zones doesn't show it.
However, when I try to create that same zone on the second PDNS
server, pdnsutil tells me that the zone already exists!
And surely enough, when I delete that zone on the first PDNS, then I
can create it on the second one - which shows that the
LMDB/Lightningstream workflow works.
The Lightningstream status webpage (http://:8500) also shows the same
metrics for both instances.
I must be missing something, but I'm having a hard time figuring out
what.
I looked at the Lightningstream doc and everything looks good.
My pdns.conf:
local-address=192.168.x.y
local-port=53
launch=lmdb
lmdb-filename=/var/spool/pdns-4.8/pdns.lmdb
lmdb-random-ids=yes
lmdb-flag-deleted=yes
lmdb-map-size=1000
lmdb-sync-mode=sync
zone-cache-refresh-interval=0
zone-metadata-cache-ttl=0
My Lightningstream YAML conf file:
instance: pdns
lmdbs:
main:
# Auth 'lmdb-filename'
path: /var/spool/pdns-4.8/pdns.lmdb
schema_tracks_changes: true
options:
no_subdir: true
create: true # optional for 'main', as auth will create it
on startup, if needed
map_size: 1000MB # for create=true, make sure to match auth's
lmdb-map-size
shard:
# Auth 'lmdb-filename' plus '-0' for the first shard
path: /var/spool/pdns-4.8/pdns.lmdb-0
schema_tracks_changes: true
options:
no_subdir: true
create: true # strongly recommended for shards
map_size: 1000MB # for create=true, make sure to match auth's
lmdb-map-size
storage:
type: s3
options:
access_key: XX
secret_key: YY
bucket: pdns
create_bucket: false
endpoint_url: https://s3.us-west-000.backblazeb2.com
http:
address: ":8500" # for status and metrics
Cheers,
