This article will explain in detail how to add disks in Vmware, the content of the article is of high quality, so the editor will share it for you as a reference. I hope you will have a certain understanding of the relevant knowledge after reading this article.

When creating a Linux, the utilization of disk space increases as the usage increases, so you need to add or expand the disk at this time.

For example, the disk of this Linux (CentOS 7.3) is 20 gigabytes, and it has been used to nearly 80%.

[root@mail ~] # cat / etc/redhat-release CentOS Linux release 7.3.1611 (Core) [root@mail ~] # dfFilesystem 1K-blocks Used Available Use% Mounted on/dev/mapper/cl_angular-root 17811456 13985948 3825508 79% / devtmpfs 1521180 01521180% / devtmpfs 1532160 01532160 0% / dev/shmtmpfs 1532160 877615233841% / runtmpfs 1532160 0 1532160 / sys/fs/cgroup/dev/sda1 1038336 123500 914836 12% / boottmpfs 306432 0 306432% / run/user/0 [root@mail ~] #

Expand disk or add disk

There are two ways under Vmware:

Add disk

Extended disk

Note: the expansion disk needs to be in a stopped state of this virtual machine, and the number of the expansion is the expected size after the expansion, such as 20g in advance, if you want to expand 10G, you should enter 30. This article uses extended disks.

Confirm statu

After expansion, restart linux and find that the state of df has not changed

[root@mail ~] # dfFilesystem 1K-blocks Used Available Use% Mounted on/dev/mapper/cl_angular-root 17811456 13985948 3825508 79% / devtmpfs 1521180 01521180% / devtmpfs 1532160 01532160 0% / dev/shmtmpfs 1532160 8776 15233841% / runtmpfs 1532160 01532160 0% / sys/fs/cgroup/dev/sda1 1038336 123500 914836 12% / boottmpfs 306432 0 306432 / run/user/0 [root@mail ~] #

Use fdisk to confirm that the disk space has been expanded

You can see "Disk / dev/sda: 32.2 GB", which has expanded 10G space.
