请教楼主：

zero.taryartar.com.               IN NS           gnsvip.zero.taryartar.com.

这个域名服务器gnsvip.zero.taryartar.com.的A记录在哪里？
# cat /var/named/taryartar.com.db
$TTL 1H        ; Time to live
$ORIGIN taryartar.com.
@       IN      SOA    mydns  root.taryartar.com.  (
                        2013011201      ; serial (todays date + todays serial #)
                        3H              ; refresh 3 hours
                        1H              ; retry 1 hour
                        1W              ; expire 1 week
                        1D )            ; minimum 24 hour

@       IN              NS mydns
;
        IN              A 192.168.0.88
mydns          IN A    192.168.0.88
gnsvip          IN A    192.168.0.89

这个“gnsvip”应该是gnsvip.taryartar.com.吧？

安装后检查报错 cluvfy comp scan

PRVG-1101 : SCAN name "tsmlinu-cluster-scan.zero2.test.com" failed to resolve

这个故障怎么排除？



grid@tsmlinux2 bin]$ cluvfy comp scan
