This article mainly explains "how to increase the virtual machine disk space of LINUX under VMware". The content of the article is simple and clear, and it is easy to learn and understand. Please follow the editor's train of thought to study and learn "how to increase the virtual machine disk space of LINUX under VMware".

There is a command line tool vmware-vdiskmanager.exe program under the VMware6.0 installation directory that can be used to modify the size of the virtual machine's hard disk. The methods are as follows:

1. Shut down the virtual machine; start the command prompt interface under Windows

two。 Enter the command into the installation directory of VMware (for example: d:\ VMware), enter "vmware-vdiskmanager" and press enter to display a description of the command.

3. Execute the following command: vmware-vdiskmanager-x 20Gb "J:\ VMware Space\ SUSE Linux 64-bit.vmdk" parameter-x indicates the virtual machine hard disk space to be expanded, followed by a number indicating the size to be expanded (for example, 20Gb, which represents the total disk capacity), and * * is the specific file of the virtual machine Linux to be operated. If there is a space in the path name, it must be enclosed in double quotation marks.

Wait about 20 minutes, finish execution, exit the command prompt window, restart VMware, and the virtual machine hard disk space has changed to 20GB. During this process, the installed Linux system will not be damaged.

If the original virtual machine hard disk has been divided into multiple partitions, then after expanding the hard disk space through vmware-vdiskmanager.exe, the additional partitions need to be partitioned and formatted in the virtual machine system.

4. Start the virtual machine system, log in with root (all subsequent steps should be logged in as root), and view it with fdisk-l on the command line. Since the original space size is directly modified here, you can see that the / dev/sda space has been changed to 21.4GB. If you add a virtual hard disk from the VMware menu, there will be one more / dev/sd?, here? Represents the hard disk number, * the hard disk number is a namely sda, the second is sdb, the third is sdc, and so on. Generally speaking, if the hard disk has not been added before, then the original hard disk is sda, and the virtual hard disk number added through the VMware menu is sdb. If the second hard drive you add is an IDE hard drive, you should see hdb. If it is a SCSI hard drive, you should see sdb.

5. Use fdisk / dev/sda to enter menu items, m to list menus, p to list partition tables, n to add partitions, and w to save and launch. Since the system already has three primary partitions, the newly added space is divided into extended partitions, and then the extended partitions are re-partitioned. Since the extended partition here is only 5G, 5G is divided into one zone.

6. Format it into ext3 format with the mkfs command.

Mkfs.ext3 / dev/sda5 7. Add folder / opt/sda5. The folder added here is to mount the newly added partition.

Mkdir-p / opt/sda5

8. Mount / dev/sda5 to / opt/sda5

Hawkzy:~ # mount / dev/sda5 / opt/sda5

View:

[email=hawkzy@hawkzy] hawkzy@ Hawkzy [/ email]: ~ > df-k

9. The files under the backup / usr folder are analyzed under / opt/sda5 / dev/sda2 / usr folder is very large, occupying 3.5 gigabytes of space. In order to free up system space, we will consider using the newly added partition as the image of / usr. The / dev/sda5 mounted by / opt/sda5 has 5G of space, which is enough to use.

Copy all files under / usr to / opt/sda5:

Cp-r / usr/* / opt/sda5/

10. Keep the / usr folder, but delete all files under / usr in preparation for mounting.

Cd / usr

Rm-rI *

11. Modify the / etc/fstab file, mount / dev/sda5 to the / usr directory, and add the following line

/ dev/sda5 / usr ext3 defaults 1 1

Restart after deletion

Init 6 .

After reboot, use the command to see whether the mount is successful or not. Under normal circumstances, it should be able to complete smoothly. If the mount fails, modify the file / etc/fstab and remount it with the command mount:

Mount / dev/sda5 / usr
