NFS服务器端（10.153.99.4）:配置如下
[root@BACKUP backup_10.153.100.3]# cat /etc/exports
/dbbackup/rman_backup/backup_10.153.100.3 10.153.100.3/24(rw,sync)
[root@BACKUP backup_10.153.100.3]# service portmap status
portmap (pid 2074) 正在运行...
[root@BACKUP backup_10.153.100.3]# service nfs status
rpc.mountd (pid 2147) 正在运行...

rpc.rquotad (pid 2132) 正在运行...
[root@BACKUP backup_10.153.100.3]# exportfs -rv
exporting 10.153.100.3:/dbbackup/rman_backup/backup_10.153.100.3
[root@BACKUP backup_10.153.100.3]#

NFS客户端（10.153.100.3）

[root@localhost /]# showmount -e 10.153.99.4
Export list for 10.153.99.4:
/dbbackup/rman_backup/backup_10.153.100.3 10.153.100.3
[root@localhost /]# mount -t nfs 10.153.99.4:/dbbackup/rman_backup/backup_10.153.100.3 /dbbackup
mount: 10.153.99.4:/dbbackup/rman_backup/backup_10.153.100.3 failed, reason given by server: 权限不够
[root@localhost /]#

为什么不能mount?

服务端面和客户端都没有防火墙，能拼通，网络正常。
10.153.99.4上面的/dbbackup本来也是nfs，在NAS存储上。
