前言

大家好，這里是浩道linux，主要給大家分享linux、python、網絡通信相關的IT知識平臺。

今天浩道跟大家分享幾個關于磁盤管理的shell腳本，助理自動化管理磁盤！?

一、實現磁盤分區的

只支持分配主分區和標準的linux文件系統(ext4/xfs)的分區

?

#!?/bin/bash
#?Function:對硬盤進行分區,得到一個標準的linux文件系統(ext4/xfs)的主分區
cat?/proc/partitions?>?old
read?-p?"請輸入你要分區的硬盤(寫絕對路徑，如：/dev/sda)："?A
if?[?-e?$A?];then
??echo?"true"
else
??echo?"該設備不存在！！"
??exit
fi
read?-p?"請輸入你要創建的磁盤分區類型(這里只能是主分區，默認按回車即可):"?B
read?-p?"請輸入分區數字，范圍1-4，默認從1開始，默認按回車即可："?C
read?-p?"請輸入扇區起始表號，默認按回車即可："?D
read?-p?"請輸入你要分區的分區大小(格式：如?+5G )："?E
fdisk?$A?<?new
F=`diff?new?old?|?grep?"<"?|?awk?'{print?$5}'`
echo?"-------------------------------"
echo?$F
echo?"你想對新分區設定什么類型的文件系統？有以下選項："
echo?"A：ext4文件系統"
echo?"B：xfs文件系統"
read?-p?"請輸入你的選擇："?G
case?$G?in
????????a|A)
???????????mkfs.ext4?/dev/$F
???????????echo?"該分區將被掛載在?"/mnt/$F"?下"?
???????????m=`ls?/mnt/|grep?$F?|?wc?-l`
???????????if?[?$m?-eq?0?];then
????????????mkdir?/mnt/$F
???????????fi
???????????n=`cat?/etc/fstab?|?grep?/dev/$F|?wc?-l`
???????????if?[?$n?-eq?0?];then
??????????????echo?"/dev/$F?????/mnt/$F?????ext4?????????defaults??????????0??????0"?>>?/etc/fstab
???????????else
??????????????sed?-i?'/^/dev/$F/c/dev/$F?????/mnt/$F?????ext4?????????defaults??????????0??????0'?/etc/fstab
???????????fi
???????????mount?-a
???????????df?-Th
;;
????????b|B)
???????????mkfs.xfs?-f?/dev/$F
???????????echo?"該分區將被掛載在?"/mnt/$F"?下"?
???????????m=`ls?/mnt/|grep?$F?|?wc?-l`
???????????if?[?$m?-eq?0?];then
??????????????mkdir?/mnt/$F
???????????fi
???????????n=`cat?/etc/fstab?|?grep?/dev/$F?|?wc?-l`
???????????if?[?$n?-eq?0?];then
??????????????echo?"/dev/$F?????/mnt/$F??????xfs???????defaults??????????0??????0"?>>?/etc/fstab
???????????else
??????????????sed?-i?'/^/dev/$F/c/dev/$F?????/mnt/$F?????xfs?????????defaults??????????0??????0'?/etc/fstab
???????????fi
???????????mount?-a
???????????df?-Th
;;
????????*)
???????????echo?"你的輸入有誤！！"
esac

二、使用一整塊硬盤創建邏輯卷

?

#!/bin/bash
#?Function:使用一整塊硬盤創建LVM邏輯卷
read?-p?"請輸入你要做成邏輯卷的硬盤(寫絕對路徑，如：/dev/sda)："?path
if?[?-e?$path?];then
??echo?"true"
else
??echo?"該設備不存在！！"
??exit
fi
pvcreate?$path
echo?"該硬盤已做成物理卷！"
vgcreate?myvg?$path
echo?"該物理卷已加入卷組?myvg?中"
vgs
free=`vgs|?awk?'$1~/myvg/{print}'|awk?'{print?$6}'`
echo?"該物理卷剩余的空間大小為：$free?"
read?-p?"請輸入你要創建邏輯卷的大小(如：1G)："?repy2
lvcreate?-L?$repy2?-n?mylv?myvg
echo?"已成功創建邏輯卷mylv"
echo?"------------------------"
lvs
echo?"------------------------"
echo?"你想對新分區設定什么類型的文件系統？有以下選項："
echo?"A：ext4文件系統"
echo?"B：xfs文件系統"
read?-p?"請輸入你的選擇："?repy3
case?$repy3?in
????????a|A)
???????????mkfs.ext4?/dev/myvg/mylv
???????????echo?"該分區將被掛載在?"/mnt/mylv"?下"?
???????????m=`ls?/mnt/|grep?mylv?|?wc?-l`
???????????if?[?$m?-eq?0?];then
????????????mkdir?/mnt/mylv
???????????fi
???????????echo?"/dev/myvg/mylv?????/mnt/mylv?????ext4?????????defaults??????????0??????0"?>>?/etc/fstab
???????????mount?-a
???????????df?-Th
;;
????????b|B)
???????????mkfs.xfs?-f?/dev/myvg/mylv
???????????echo?"該分區將被掛載在?"/mnt/mylv"?下"?
???????????m=`ls?/mnt/|grep?mylv?|?wc?-l`
???????????if?[?$m?-eq?0?];then
??????????????mkdir?/mnt/mylv
???????????fi
???????????echo?"/dev/myvg/mylv?????/mnt/mylv??????xfs???????defaults??????????0??????0"?>>?/etc/fstab
???????????mount?-a
???????????df?-Th
;;
????????*)
???????????echo?"你的輸入有誤！！"
esac

三、將一塊硬盤分區，然后分區設置為虛擬卷

?

#!?/bin/bash
#?Author:謝公子
#?Date:2018-10-13
#?Function:新建一個分區，并做成邏輯卷
cat?/proc/partitions?>?old
read?-p?"請輸入你要分區的硬盤(寫絕對路徑，如：/dev/sda)："?A
if?[?-e?$A?];then
??echo?"true"
else
??echo?"該設備不存在！！"
??exit
fi
read?-p?"請輸入你要創建的磁盤分區類型(這里只能是主分區，默認按回車即可):"?B
read?-p?"請輸入分區數字，范圍1-4，默認從1開始，默認按回車即可："?C
read?-p?"請輸入扇區起始表號，默認按回車即可："?D
read?-p?"請輸入你要分區的分區大小(格式：如?+5G )："?E
read?-p?"請輸入你要劃分為邏輯卷的分區盤符(默認回車即可)："?Z
fdisk?$A?<?new
F=`diff?new?old?|?grep?"<"?|?awk?'{print?$5}'`
echo?"-------------------------------"
echo?$F
pvcreate?/dev/$F
echo?"該硬盤已做成物理卷！"
n=`vgs?|?grep?myvg?|wc?-l`
if?[?$n?-eq?0?];then
???vgcreate?myvg?/dev/$F
???echo?"該物理卷已加入卷組myvg中"
else
???vgextend?myvg?/dev/$F
???echo??"該物理卷已加入卷組myvg中"
???vgs
???free=`vgs|?awk?'$1~/myvg/{print}'|awk?'{print?$7}'`
???echo?"該卷組剩余的空間大小為：$free?"
???lvs
???exit
fi
vgs
free=`vgs|?awk?'$1~/myvg/{print}'|awk?'{print?$6}'`
echo?"該卷組剩余的空間大小為：$free?"
read?-p?"請輸入你要創建邏輯卷的大小(如：1G)："?repy2
lvcreate?-L?$repy2?-n?mylv?myvg
echo?"已成功創建邏輯卷mylv"
echo?"------------------------"
lvs
echo?"------------------------"
echo?"你想對新分區設定什么類型的文件系統？有以下選項："
echo?"A：ext4文件系統"
echo?"B：xfs文件系統"
read?-p?"請輸入你的選擇："?G
case?$G?in
????????a|A)
???????????mkfs.ext4?/dev/myvg/mylv
???????????echo?"該分區將被掛載在?"/mnt/$F"?下"?
???????????m=`ls?/mnt/|grep?$F?|?wc?-l`
???????????if?[?$m?-eq?0?];then
????????????mkdir?/mnt/$F
???????????fi
???????????echo?"/dev/myvg/mylv?????/mnt/$F?????ext4?????????defaults??????????0??????0"?>>?/etc/fstab
???????????mount?-a
???????????df?-Th
;;
????????b|B)
???????????mkfs.xfs?-f?/dev/myvg/mylv
???????????echo?"該分區將被掛載在?"/mnt/$F"?下"?
???????????m=`ls?/mnt/|grep?$F?|?wc?-l`
???????????if?[?$m?-eq?0?];then
??????????????mkdir?/mnt/$F
