Linux下調(diào)整根目錄的空間大小

一悠瞬、目的

在使用CentOS6.3版本linux系統(tǒng)的時候昵骤，發(fā)現(xiàn)根目錄(/)的空間不是很充足，而其他目錄空間有很大的空閑交惯，所以本文主要是針對現(xiàn)在已有的空間進(jìn)行調(diào)整次泽。首先，先來查看一下系統(tǒng)的空間分配情況：

[root@CentOS-78?/]#?df?-h

Filesystem????????????Size??Used?Avail?Use%?Mounted?on

/dev/mapper/vg_centos-lv_root

50G???14G???34G??30%?/

tmpfs?????????????????1.9G?????0??1.9G???0%?/dev/shm

/dev/sda1?????????????485M???37M??423M???8%?/boot

/dev/mapper/vg_centos-lv_home

404G??670M??382G???1%?/home

下面的詳細(xì)步驟部分將從vg_centos-lv_home分區(qū)下取出100G的空間添加到/vg_centos-lv_root分區(qū)上去席爽。

二意荤、詳細(xì)步驟

1、卸載vg_centos-lv_home分區(qū)

[root@CentOS-78?/]#?umount?/home

此時在用df命令查看將會發(fā)現(xiàn)/home目錄已經(jīng)看不見了只锻，如下所示：

[root@CentOS-78?/]#?df?-h

Filesystem????????????Size??Used?Avail?Use%?Mounted?on

/dev/mapper/vg_centos-lv_root

50G???14G???34G??30%?/

tmpfs?????????????????1.9G?????0??1.9G???0%?/dev/shm

/dev/sda1?????????????485M???37M??423M???8%?/boot

2玖像、從新設(shè)定vg_home-lv_home的大小

[root@CentOS-78?/]#?resize2fs?-p?/dev/mapper/vg_centos-lv_home?282G

resize2fs?1.41.12?(17-May-2010)

Please?run?'e2fsck?-f?/dev/mapper/vg_centos-lv_home'?first.

這一步設(shè)定vg_home-lv_home大小沒有成功，系統(tǒng)提示我們先運行下面的命令齐饮，操作如下：

[root@CentOS-78?/]#?e2fsck?-f?/dev/mapper/vg_centos-lv_home

e2fsck?1.41.12?(17-May-2010)

Pass?1:?Checking?inodes,?blocks,?and?sizes

/dev/mapper/vg_centos-lv_home:?1386/26836992?files?(0.9%?non-contiguous),?1855856/107344896?blocks

從新設(shè)定vg_home-lv_home的大芯枇取：

[root@CentOS-78?/]#?resize2fs?-p?/dev/mapper/vg_centos-lv_home?282G

resize2fs?1.41.12?(17-May-2010)

Resizing?the?filesystem?on?/dev/mapper/vg_centos-lv_home?to?73924608?(4k)?blocks.

檢查是否成功：

[root@CentOS-78?/]#?mount?/home

[root@CentOS-78?/]#

[root@CentOS-78?/]#?df?-h

Filesystem????????????Size??Used?Avail?Use%?Mounted?on

/dev/mapper/vg_centos-lv_root

50G???14G???34G??30%?/

tmpfs?????????????????1.9G?????0??1.9G???0%?/dev/shm

/dev/sda1?????????????485M???37M??423M???8%?/boot

/dev/mapper/vg_centos-lv_home

278G??663M??263G???1%?/home

[root@CentOS-78?/]#

3、將lv_home邏輯分區(qū)減小到指定大小

[root@CentOS-78?/]#?lvreduce?-L?282G?/dev/mapper/vg_centos-lv_home

WARNING:?Reducing?active?and?open?logical?volume?to?282.00?GiB

THIS?MAY?DESTROY?YOUR?DATA?(filesystem?etc.)

Do?you?really?want?to?reduce?lv_home??[y/n]:?y

Reducing?logical?volume?lv_home?to?282.00?GiB

Logical?volume?lv_home?successfully?resized

[root@CentOS-78?/]#

我認(rèn)為這個命令是將已經(jīng)減少的100G空間拿到系統(tǒng)公共的區(qū)域祖驱，可以被其他分區(qū)加載和利用握恳。

查詢卷組的信息：

[root@CentOS-78?/]#?vgdisplay

---?Volume?group?---

VG?Name???????????????vg_centos

System?ID

Format????????????????lvm2

Metadata?Areas????????1

Metadata?Sequence?No??5

Free??PE?/?Size???????32637?/?127.49?GiB

VG?UUID???????????????1k4ooN-RFV9-uyf1-uMYf-aERG-YaGs-ZNoSD6

Free PE / Size指定的應(yīng)該是現(xiàn)在可在分配的空間。

4捺僻、增加vg_centos-lv_root分區(qū)的大小

將可用的空間添加到vg_centos-lv_root分區(qū)上面：

[root@CentOS-78?/]#?lvextend?-L?+127.40G?/dev/mapper/vg_centos-lv_root

Rounding?up?size?to?full?physical?extent?127.40?GiB

Extending?logical?volume?lv_root?to?177.40?GiB

Logical?volume?lv_root?successfully?resized

[root@CentOS-78?/]#

從新設(shè)定該分區(qū)的大兴ァ：

[root@CentOS-78?/]#?resize2fs?-p?/dev/mapper/vg_centos-lv_root

resize2fs?1.41.12?(17-May-2010)

Filesystem?at?/dev/mapper/vg_centos-lv_root?is?mounted?on?/;?on-line?resizing?required

old?desc_blocks?=?4,?new_desc_blocks?=?12

Performing?an?on-line?resize?of?/dev/mapper/vg_centos-lv_root?to?46504960?(4k)?blocks.

The?filesystem?on?/dev/mapper/vg_centos-lv_root?is?now?46504960?blocks?long.

5、再次查看分區(qū)大小

[root@CentOS-78?/]#?df?-h

Filesystem????????????Size??Used?Avail?Use%?Mounted?on

/dev/mapper/vg_centos-lv_root

175G???14G??153G???9%?/

tmpfs?????????????????1.9G?????0??1.9G???0%?/dev/shm

/dev/sda1?????????????485M???37M??423M???8%?/boot

/dev/mapper/vg_centos-lv_home

278G??663M??263G???1%?/home

我們發(fā)現(xiàn)vg_centos-lv_root分區(qū)的空間已經(jīng)增加了125G陵像，之所以比lv_home減少的空間要多25G主要是由于我們把系統(tǒng)所有的可用的空間都加在了lv_root分區(qū)就珠。

三、所遇到的問題

1醒颖、在卸載/home目錄的時候失敗

可先執(zhí)行如下fuser命令妻怎，然后再umount即可：

[root@CentOS-78?/]#?fuser?-m?/home

[root@CentOS-78?/]#

2、設(shè)定完lv_home的大小泞歉，再次mount該分區(qū)時逼侦，發(fā)現(xiàn)用df命令無法看到給分區(qū)匿辩，此時只要在mount一次即可

3、在設(shè)定lv_root的大小時榛丢，不要把Free PE / Size的空間全部都用上铲球，這很可能會出現(xiàn)Free PE空間不足的現(xiàn)象，建議保留一點Free PE的空間晰赞。

在Fedora13-x86_64 擴展 VolGroup-lv_root 分區(qū).

在使用Fedora13-x86_64過程中,發(fā)現(xiàn)系統(tǒng)分配給root用戶lvm份額太少.

[root@localhost ~]# df -h

Filesystem Size Used Avail Use% Mounted on

/dev/mapper/VolGroup-lv_root

50G 11G 37G 23% /

tmpfs 878M 100K 878M 1% /dev/shm

/dev/sda1 485M 28M 432M 7% /boot

/dev/sdc 124M 107M 18M 86% /media/16F0-286F

[root@localhost ~]#

總共才50G,決定給它增加份額,現(xiàn)做好重要文件備份,以防萬一.

思路:

先減掉VolGroup-lv_home的份額,再把減掉份額增加到VolGroup-lv_root.

[root@localhost ~]# pvscan

已經(jīng)可以了.

linux增加根目錄的磁盤空間(LVM)

第一步：添加磁盤

第二步：使用Linux下的fdisk工具進(jìn)行分區(qū)

用root用戶登錄：

打印當(dāng)前的磁盤分區(qū)表稼病，這時我們可以看到磁盤的總量的確增加到30GB 了，但是分區(qū)只有以前的那幾個原有的分區(qū)

[root@localhost ~]# fdisk -l

鍵入命令： fdisk /dev/sda?? “sda 就是經(jīng)過擴容的硬盤掖鱼，為 SCSI 硬盤然走， IDE 類型硬盤對應(yīng)為 hda ，是對該硬盤進(jìn)行操作 ”

選擇主分區(qū)吧戏挡，則鍵入 p

此時芍瑞， fdisk 會讓你選擇主分區(qū)的編號，如果已經(jīng)有了主分區(qū) sda1 褐墅， sda2 拆檬，那么編號就選3 ，即要創(chuàng)建的該分區(qū)為 sda3.

鍵入：???? 3

此時妥凳， fdisk 又會讓你選擇該分區(qū)的開始值這個就是分區(qū)的 Start 值（ start cylinder ）竟贯；這里最好直接按回車， 如果您輸入了一個非默認(rèn)的數(shù)字猾封，可能會造成空間浪費澄耍；

對于分區(qū)的 End 值（end cylinder），同樣直接按回車晌缘。這時候會顯示出你新建分區(qū)的柱面范圍和空間大小齐莲。

此時鍵入： w??? 表示" 保存所有并退出，分區(qū)劃分完畢 "

[root@localhost ~]# fdisk /dev/sda

The number of cylinders for this disk is set to 3916.

There is nothing wrong with that, but this is larger than 1024,

and could in certain setups cause problems with:

2) booting and partitioning software from other OSs
