【Linux】将Oracle安装目录从根目录下迁移到逻辑卷
1.1 BLOG文档结构图
1.2 前言部分
1.2.1 导读和注意事项
各位技术爱好者，看完本文后，你可以掌握如下的技能，也可以学到一些其它你所不知道的知识，~O(∩_∩)O~：
① Linux逻辑卷的创建和管理（重点）
1.2.2 相关文章链接
linux逻辑卷管理：http://blog.itpub.net/26736162/viewspace-2124620/，这篇文章非常不错。
1.2.3 本文简介
由于Oracle版本太多，鉴于学习使用，所以，小麦苗在RHEL6.5上安装了Oracle 11.2.0.3、Oracle 10.2.0.1和Oracle 10.2.0.4。但是由于没有采用逻辑卷的管理方式，现在根目录磁盘空间不足，而且也添加了好几块硬盘了，管理非常不方便。以后等Oracle 12cR2出来后还得安装在一起，想了想还是一次性将这些Oracle的安装目录都迁移到逻辑卷中，以后也好管理。本文记录了迁移过程，以备有同样需求的朋友使用。
1.3 迁移过程
1.3.1 磁盘现状
最后操作的结果就是把磁盘2、3、4和5去掉，只剩下1块或2块磁盘。
1.3.2 分区并创建物理卷
