[Pdns-users] Issue with lightningstream replication not working

[Nico Cartron]

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
