Virtual machine 增加虚拟机的磁盘空间

正如您在下面的命令中所看到的，我已经为我的虚拟机分配了总共500 GB的磁盘空间。但我看到了14.4 GB的实际可用磁盘空间，一旦它被完全使用。我出错了没有多少空间可以使用？如何扩展/dev/mapper/centos root的空间

我正在使用VMware ESXi和centOS来实现此虚拟机

[root@localhost Apr]# fdisk -l

Disk /dev/sda: 536.9 GB, 536870912000 bytes, 1048576000 sectors
Units = sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk label type: dos
Disk identifier: 0x00064efd

   Device Boot      Start         End      Blocks   Id  System

Disk /dev/mapper/centos-root: 14.4 GB, 14382268416 bytes, 28090368 sectors

Disk /dev/mapper/centos-swap: 1719 MB, 1719664640 bytes, 3358720 sectors

Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 byte

在VMWare中添加空间后，执行以下步骤以增加Linux磁盘：

步骤1-更新分区表

fdisk/dev/sda

步骤2-重新启动虚拟机

步骤3-验证更改是否已保存

fdisk-l

步骤4-将新分区转换为物理卷

步骤5-扩展物理卷（centos是您的VG名称，如果不是，请使用您的VG名称代替centos）

vgextend centos/dev/sda3

步骤6-扩展逻辑卷（500G是要添加的大小，如果不是，请使用正确的大小代替500G）

lvextend-L+500G/dev/mapper/centos root

步骤7-联机扩展ext文件系统

调整大小2FS/dev/mapper/centos root

Press p to print the partition table to identify the number of partitions.
Press n to create a new primary partition.
Press p for primary.
Press 3 for the partition number, depending on the output of the partition table print.
Press Enter two times.
Press t to change the system's partition ID.
Press 3 to select the newly creation partition.
Type 8e to change the Hex Code of the partition for Linux LVM.
Press w to write the changes to the partition table.

pvcreate /dev/sda3
