xCAT 2.7.6 dns解析

之前一直遇到这个问题

[root@mgmt3 ~]host node01

;; connection timed out; trying next origin

;; connection timed out; no servers could be reached

[root@mgmt3 ~]nslookup node01

;; connection timed out; trying next origin

[root@mgmt3 ~]dig @192.168.10.254 node01

; <<>> DiG 9.8.2rc1-RedHat-9.8.2-0.10.rc1.el6 <<>> @192.168.10.254 node01

; (1 server found)

;; global options: +cmd

;; connection timed out; no servers could be reached

还有就是在makedns时候，会在Getting reverse zones, this may take several minutes in scaling cluster. Updating DNS records, this may take several minutes in scaling cluster.停留很久。

最后cat /var/named/db.cluster.com

[root@mgmt3 ~]# cat /var/named/db.cluster.com
$TTL 86400
@IN SOA  mgmt3.cluster.com. root.mgmt3.cluster.com. (2013040901 10800 3600 604800  86400 )
IN NS      mgmt3.cluster.com.
mgmt3                   A       192.168.10.254

之前一直遇到这个问题，发现这个问题已经在2.8中被修复了

当然如果也可以尝试用makedns -n来重新产生dns文件

然后在Scaling cluster那里很快就过了，并且db.cluster.com中也有信息了

[root@mgmt3 ~]# cat /var/named/db.cluster.com
$ORIGIN .
$TTL 86400      ; 1 day
cluster.com             IN SOA  mgmt3.cluster.com. root.mgmt3.cluster.com. (

                                10800      ; refresh (3 hours)
                                3600       ; retry (1 hour)
                                604800     ; expire (1 week)
                                86400      ; minimum (1 day)
                                )
                        NS      mgmt3.cluster.com.
