Hi,
I have some questions regarding the integration of PostgreSQL replication and
PowerDNS operating in native mode.
As the replication of Postgres is a master - slave replication the transactions
on the slaves are read-only.
- Is there a way to delegate all write operations the the PowerDNS “master” (the one
using the PostgreSQL master instance), like "forward-dnsupdate=yes” does for
dnsupdates?
Are there any write operations? In native mode I guess there shouldn'T
be any write queries - maybe only for DNSSEC key management.
Maybe if you do some fancy stuff only against the PowerDNS which uses
the Postgres-Master then it should work.
- How does the DNSSEC inception works with the native mode? Will the “master”
try to re-sign the zone or are all PowerDNS servers trying to re-sign the zone
(with failures on the read-only databases)?
AFAIK PowerDNS does online-signing - hence the signatures are not in the
DB. Hence, every node does signing on its own (A PowerDNS server does
not know if the Postgresql DB is a replication slave or master).
What exactly is your problem?
regards
Klaus
