Hello,
From what I've seen, when using an external DNS server, xCAT's
'makedns' command looks for the NS records for the zone and sends them
the update.
What's the reasoning behind this instead of, let's say, sending the
update to the MNAME field (primary master) of the SOA record, as for
instance the 'nsupdate' command does when no 'server' directive is used ?
As a matter of fact, in a setup consisting of (with bind/named) :
- a (hidden) master
- 2 slaves (only them have the NS records for the zone)
it leads to unneccessary transfers :
- xCAT sends update to slave(s)
- slaves forward the update to the master
- master notify the slaves
- records get transfered from master to slaves
Thanks
