目的：
当时装操作系统没有给/opt单独挂载磁盘，现在要扩大磁盘空间，新增一块磁盘600G单独给/opt挂载
创建sdb1的过程省略，可参考http://allenyu.blog.51cto.com/193668/156256/
mount /dev/sdb1 /mnt
停掉ORACLE服务，将/opt所有目录下的东西拷贝至/mnt, /dev/sdb1中就要有跟/opt相同的目录结构，然后挂载 mount /dev/sdb1 /opt。
给/etc/fstab中写入
让其开机自动挂载，挂载成功后
1.然后启动oracle数据库监听，报错。
进入/opt/ora10/lib文件夹，检查libclntsh.so.10.1是否存在
文件确实存在，
此文件的路径为 /opt/ora10/lib
2.用root用户登录，修改该/etc/ld.so.conf添加/opt/ora10/lib路径

3.未解决，再持行chmod -R 755 /opt/ora10/后lsnctrl start启动成功
su - oracle
4.sqlplus / as sysdba登录报出错误ORA-09925: Unable to create audit trail filev
登不进去
chown –R oracle.oinstall /opt/ora10g

问题解决可以在里面建立新的表空间，新的用户，链接数据库正常，数据库目录重新挂载成功
