[Felix New]

Hi all,

we have one master server and several slave servers with Bind 9.9.2-P1, and
service for about 50K zones.

i shutdown one slave,start it, then a lot of transfer between the slave and
server:

the check transfer(maybe this is usefull for consistency) will take a lot
of time, for example several hours. in the meantime, if the master added
new RR and send notify to the slave, the transfer not start(may be added to
the end of transfer queue, new Inconsistency).

Can i skip the check transfer after slave start? if not ,can speed up?

options state in the named.conf of master:
options {
        listen-on port 53 {10.198.190.1;};
        directory "/var/named/master";
        pid-file "named.pid";
        version "v2";
        transfer-format many-answers;
        transfers-in  1000;
        transfers-out 1000;
        transfers-per-ns 2000;
        allow-new-zones yes;
        zone-statistics yes;
        recursion no;
        check-integrity no;
        allow-update { key rndc-key; };
        notify yes;
        also-notify {10.198.190.2; };
        allow-transfer { localhost; 10.198.190.1; 10.198.190.2; };
};

options state in the named.conf of slave:
options {
        listen-on port 53 {10.198.190.2;};
        directory "/var/named/slave";
        pid-file "named.pid";
        version "v2";
        allow-new-zones yes;
        notify no;
        allow-transfer { none; };
        transfer-format many-answers;
        transfers-in  1000;
        transfers-out 1000;
        transfers-per-ns 2000;
        recursion no;
};
