                                             ---------------尽管所有者已更改为oracle，但后面oracle模式,raman 备份依旧提示没有权限，permission denied;
  [root@his2 /]# chmod 777 hisback    ---------------修改hisback 权限为777，u=7,g=7,o=7

• [root@his2 /]#  mount -o username=hisbackup,password=hisbackup //192.168.1.1/his1rman /hisback  ----------我当时是用这个命令挂载的，网络盘确实挂载上了，但这种命令没法赋予权限。

1. [root@his2 hisback]# id oracle     --------------查看oracle的uid和gid
   uid=1002(oracle) gid=1001(oinstall) groups=1001(oinstall),1002(dba),1004(asmdba)
2. [root@his2 /]# mount -t smbfs -o username="hisbackup",password="hisbackup",gid="1001",uid="1002" //172.16.2.99/his1rman /hisback
   mount: unknown filesystem type 'smbfs'  -----------------发现有报错，尝试用cifs
3. [root@his2 /]# mount -t cifs -o username="hisbackup",password="hisbackup",gid="1001",uid="1002" //192.168.1.1/his1rman /hisback   ------//192.168.1.1/his1rman为局域网windows网络共享磁盘，/hisback为挂载点。
   Refer to the mount.cifs(8) manual page (e.g. man mount.cifs)   --------------成功挂载
4. ####  如果不加uid,gid，挂载时默认缺省所有者，所属组为root,加这个就是修改挂载时默认所有者和属组为oracle
5. [root@his2 /]# mount                -------------mount一下查看，挂载状态

9. 永久挂载:通过修改 vim /etc/fstab 实现挂载，

10. 例如：增加 /dev/sdb1 /home/newdisk ext4 default 0 0  /*为新增sdb1磁盘，开机自动挂载*/

11. 添加完成后，执行 mount -a 即可生效。
