VMware disk expansion record

1 Original disk size

2 VMwareDisk expansion settings

VMware面板中"我的计算机"Select the virtual machine that needs disk expansion,右击“设置”,在“虚拟机设置”页面,选择“硬盘”–>“扩展”：

调整磁盘大小：

Click the extension to get the following tips,点击确认即可.

3 operating system settings

1、Increase the disk partition

fdisk /dev/sda

依次输入m、n、p、回车、回车、w保存,Forgot to take screenshots in this section,具体操作可参考https://blog.csdn.net/qq_44297579/article/details/107318096中的“2.管理sda磁盘”内容.

2、重启操作系统
3、进行第三步操作–>添加新LVM到已有的LVM组,实现卷扩容

lvm　　　　　　　　　　　　           #进入lvm管理

lvm>pvcreate /dev/sda4　　           #这是初始化刚才的分区4

lvm>vgextend centos /dev/sda4     #将初始化过的分区加入到虚拟卷组centos (卷和卷组的命令可以通过 vgdisplay )

直接执行vgextend centos /dev/sda4后报错,After thinkingcentosShould be the name of a volume or volume group,It should be different from the original blogger,根据后面的注释,执行vgdisplay命令,结果为空.至此,The subsequent actions cannot be followed（If it can go well,You can continue to operate according to the steps of the original blogger）.

4、创建物理卷和卷组

pvcreate /dev/sda4

5、添加挂载点

[[email protected] /]# mount /dev/sda4 /testspace
mount: unknown filesystem type 'LVM2_member'
[[email protected] /]#

如上,报错.

参考文章 https://blog.csdn.net/whatday/article/details/106135126 ,Check the current status of the server as follows --> This workaround does not apply to this issue.

# 查看物理卷
[[email protected] /]# pvs
  PV         VG Fmt  Attr PSize  PFree
  /dev/sda4     lvm2 ---  10.00g 10.00g
[[email protected] /]#

# 查看卷组 --> 无数据
[[email protected] /]# vgs
[[email protected] /]#

# 查看逻辑卷 --> 无数据 
[[email protected] /]# lvdisplay
[[email protected] /]#

最后,参考文章 https://blog.csdn.net/colin_yu/article/details/77892918 中的方案二 The partition was formatted directly：

[[email protected] opt]# mkfs -t ext4 -c /dev/sda4
mke2fs 1.42.9 (28-Dec-2013)
Filesystem label=

Block size=4096 (log=2)

再次挂载 --> 成功：

4 Check the disk status after expansion

# 查看磁盘分区情况
[[email protected] opt]# lsblk -f
