交互式Shell脚本实现Linux物理卷管理
# Linux LVM Tool完整版本: http://xin23.blog.51cto.com/1827266/1198836(update 2013.5.13)# 脚本仅供交流学习使用！
# 脚本当前版本为1.0.实现了物理卷的创建,移除,更改(启用/禁用分配),扫描,查看功能.# 后续会补齐卷组和逻辑卷的管理,整合成一个Linux LVM TOOL.类似于AIX的SMIT.虽然,它只能管理LVM.# 脚本已在Red Hat Enterprise Linux 5.4 64bit上测试通过.原则上适用于RHEL 5和RHEL 6.# 欢迎提出改进意见.# 直接复制请注意标点符号.也可通过微盘下载文件,避免复制引起的问题:http://vdisk.weibo.com/s/zKW6M#!/bin/bash# Version 1.0# AUTHOR:Xin23 http://weibo.com/231988PV(){NextLine(){ echo ' '}Split(){ echo '-----------------------------------------------------------------------'}EchoTitle(){ echo "--------$Title-----------------------------------------"}ShowPVFirstMenu(){ echo ' Physical Volumn Main Menu Input Number To Choose!
