RMAN 备份时提示错误，如下 ：

[root@rac2 ~]# su - oracle
  /home/oracle@rac2>rman target /;

经过哈哈朋友帮忙后，发现10G的挂载有点小技巧。

这个是原先的挂载方式。

[root@rac2 ~]# mount -o tcp 192.168.0.240:/nfsshare/ /orabk;

 

修改为 ：

[root@rac2 ~]# mount /orabk;

[root@rac2 ~]# df -h
Filesystem            Size  Used Avail Use% Mounted on
/dev/sda1             119G   41G   73G  36% /
none                  7.9G     0  7.9G   0% /dev/shm
192.168.0.240:/nfsshare
                      3.6T  2.6T 1008G  73% /orabk

 

重新备份就成功了；
