This article mainly explains "how to expand the CentOS partition in the VMware virtual machine". The content in 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 expand the CentOS partition in the VMware virtual machine".

Due to the insufficient root partition planning of the development and test machine dev-vhost017, it is only 10G, so it needs to be expanded. (based on LVM)

Close dev-vhost017 first, and then adjust the root partition hard disk from 10g to 50g in vSphere Client

Turn on the virtual machine

Original / size 10G

The code is as follows:

[root@dev-vhost017] # df-h

Filesystem Size Used Avail Use% Mounted on

/ dev/sda1 477M 57M 396M 13% / boot

Check that disk sda has been expanded to 50G

The code is as follows:

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