报错如下：

[root@11grac1 .ssh]# mount -t nfs  192.168.137.141:/mnt/rac_ogg/rac_ogg /u01/app/ogg/11.1
mount: 192.168.137.141:/mnt/rac_ogg/rac_ogg failed, reason given by server: Permission denied

在nfs服务端查看配置文件：

[root@openfiler rac_ogg]# cat /etc/exports

# End of Openfiler configuration

/mnt/rac_ogg/rac_ogg  192.168.137.*(rw,sync,no_root_squash,no_all_squash,no_subtree_check) 

修改后如下：

[root@openfiler rac_ogg]# cat /etc/exports

# PLEASE DO NOT MODIFY THIS CONFIGURATION FILE!
#       This configuration file was autogenerated
#       by Openfiler. Any manual changes will be overwritten
