前言
大家好，這里是浩道linux，主要給大家分享linux、python、網(wǎng)絡(luò)通信相關(guān)的IT知識平臺。
今天浩道跟大家分享幾個關(guān)于磁盤管理的shell腳本，助理自動化管理磁盤！?
一、實現(xiàn)磁盤分區(qū)的
只支持分配主分區(qū)和標(biāo)準(zhǔn)的linux文件系統(tǒng)(ext4/xfs)的分區(qū)
?
#!?/bin/bash #?Function:對硬盤進(jìn)行分區(qū),得到一個標(biāo)準(zhǔn)的linux文件系統(tǒng)(ext4/xfs)的主分區(qū) cat?/proc/partitions?>?old read?-p?"請輸入你要分區(qū)的硬盤(寫絕對路徑，如：/dev/sda)："?A if?[?-e?$A?];then ??echo?"true" else ??echo?"該設(shè)備不存在??！" ??exit fi read?-p?"請輸入你要創(chuàng)建的磁盤分區(qū)類型(這里只能是主分區(qū)，默認(rèn)按回車即可):"?B read?-p?"請輸入分區(qū)數(shù)字，范圍1-4，默認(rèn)從1開始，默認(rèn)按回車即可："?C read?-p?"請輸入扇區(qū)起始表號，默認(rèn)按回車即可："?D read?-p?"請輸入你要分區(qū)的分區(qū)大小(格式：如?+5G )："?E fdisk?$A?<?new F=`diff?new?old?|?grep?"<"?|?awk?'{print?$5}'` echo?"-------------------------------" echo?$F echo?"你想對新分區(qū)設(shè)定什么類型的文件系統(tǒng)？有以下選項：" echo?"A：ext4文件系統(tǒng)" echo?"B：xfs文件系統(tǒng)" read?-p?"請輸入你的選擇："?G case?$G?in ????????a|A) ???????????mkfs.ext4?/dev/$F ???????????echo?"該分區(qū)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(qū)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(chuàng)建邏輯卷
?
#!/bin/bash
#?Function:使用一整塊硬盤創(chuàng)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?$path?];then
??echo?"true"
else
??echo?"該設(shè)備不存在！！"
??exit
fi
pvcreate?$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(chuàng)建邏輯卷的大小(如：1G)："?repy2
lvcreate?-L?$repy2?-n?mylv?myvg
echo?"已成功創(chuàng)建邏輯卷mylv"
