У ведомого сервера имен Bind9 проблемы с передачей основного файла

У меня настроен главный сервер имен, и сейчас я пытаюсь настроить подчиненное устройство. Bind9 загружается и работает нормально, однако я получаю следующую ошибку:

Apr 27 12:47:21 ns2 named[23563]: dumping master file: slaves/tmp-oJ5LJ1RtO4: open: file not found

Вот мой файл named.conf.options:

options {

recursion yes;
allow-recursion { trusted; };
listen-on { 10.0.1.11; }; //this machines IP. 
allow-transfer { none; };

// If there is a firewall between you and nameservers you want
// to talk to, you may need to fix the firewall to allow multiple
// ports to talk.  See http://www.kb.cert.org/vuls/id/800113

// If your ISP provided one or more IP addresses for stable 
// nameservers, you probably want to use them as forwarders.  
// Uncomment the following block, and insert the addresses replacing 
// the all-0's placeholder.

forwarders {
    10.0.1.12;
    x.x.x.x; //keeping my ISPs nameservers private for post in askUbunutu
    x.x.x.x; //
};

//========================================================================
// If BIND logs error messages about the root key being expired,
// you will need to update your keys.  See https://www.isc.org/bind-keys
//========================================================================
dnssec-validation auto;

auth-nxdomain no;    # conform to RFC1035
listen-on-v6 { any; };

};

Slaves named.conf.local file:

//
// Do any local configuration here
//

// Consider adding the 1918 zones here, if they are not used in your
// organization
//include "/etc/bind/zones.rfc1918";
zone "mycity.example.com" {
type slave;
file "slaves/db.mycity.example.com";
masters { 10.0.1.12; };
};

zone "1.0.10.in-addr.arpa" {
    type slave;
    file "slaves/db.10";
    masters { 10.0.1.12; };
};

Права доступа к каталогу для / etc / bind / slaves

drwxr-sr-x   2 bind bind  4096 Apr 27 09:41 slaves

Есть идеи, что я делаю неправильно?
