這篇文章主要講解了“怎么給VMware虛擬機(jī)中的CentOS分區(qū)擴(kuò)容”，文中的講解內(nèi)容簡單清晰，易于學(xué)習(xí)與理解，下面請大家跟著小編的思路慢慢深入，一起來研究和學(xué)習(xí)“怎么給VMware虛擬機(jī)中的CentOS分區(qū)擴(kuò)容”吧！

林芝網(wǎng)站制作公司哪家好，找創(chuàng)新互聯(lián)！從網(wǎng)頁設(shè)計、網(wǎng)站建設(shè)、微信開發(fā)、APP開發(fā)、成都響應(yīng)式網(wǎng)站建設(shè)等網(wǎng)站項(xiàng)目制作，到程序開發(fā)，運(yùn)營維護(hù)。創(chuàng)新互聯(lián)自2013年創(chuàng)立以來到現(xiàn)在10年的時間，我們擁有了豐富的建站經(jīng)驗(yàn)和運(yùn)維經(jīng)驗(yàn)，來保證我們的工作的順利進(jìn)行。專注于網(wǎng)站建設(shè)就選創(chuàng)新互聯(lián)。

由于開發(fā)測試機(jī)器dev-vhost017根分區(qū)規(guī)劃不足只有10G,需要擴(kuò)容。(基于LVM)

先關(guān)閉dev-vhost017，然后在vSphere Client 將根分區(qū)硬盤10G 調(diào)整到50G

開啟虛擬機(jī)
原始/ 大小 10G

代碼如下:

[root@dev-vhost017 ~]# df -h

Filesystem            Size  Used Avail Use% Mounted on
/dev/mapper/vg_centos6-lv_root
                      8.3G  4.0G  3.9G  51% /
tmpfs                 939M   12K  939M   1% /dev/shm
/dev/sda1             477M   57M  396M  13% /boot

查看磁盤sda已擴(kuò)展到50G

代碼如下:

[root@dev-vhost017 ~]# fdisk /dev/sda

         switch off the mode (command 'c') and change display units to
         sectors (command 'u').

查看lvm狀態(tài)

代碼如下:

[root@dev-vhost017 ~]# pvs

  PV         VG         Fmt  Attr PSize PFree
  /dev/sda2  vg_centos6 lvm2 a--  9.51g    0

代碼如下:

[root@dev-vhost017 ~]# vgs

  VG         #PV #LV #SN Attr   VSize VFree
  vg_centos6   1   2   0 wz--n- 9.51g    0

代碼如下:

[root@dev-vhost017 ~]# lvs

  LV      VG         Attr       LSize Pool Origin Data%  Meta%  Move Log Cpy%Sync Convert
  lv_root vg_centos6 -wi-ao---- 8.51g                                                  
  lv_swap vg_centos6 -wi-ao---- 1.00g

分區(qū)/dev/sda3

代碼如下:

[root@dev-vhost017 ~]# fdisk /dev/sda

/dev/sda3            1306        6527    41942367+  83  Linux

代碼如下:

[root@dev-vhost017 ~]# partprobe

重啟虛擬機(jī) 格式化/dev/sda3

代碼如下:

[root@dev-vhost017 ~]# mkfs.ext4 /dev/sda3

lvm 擴(kuò)容

代碼如下:

[root@dev-vhost017 ~]# pvcreate  /dev/sda3

  Physical volume "/dev/sda3" successfully created

代碼如下:

[root@dev-vhost017 ~]# pvs

代碼如下:

[root@dev-vhost017 ~]# vgextend /dev/mapper/vg_centos6 /dev/sda3 (注意組名)

  Volume group "vg_centos6" successfully extended

代碼如下:

[root@dev-vhost017 ~]# lvextend -L 39.9G /dev/vg_centos6/lv_root /dev/sda3
