Managing virtual disks with fsdisk

Introduction

Managing virtual disks with fsdisk is an essential task for system administrators who work with virtual machines. Fsdisk is a command-line tool that allows users to create, delete, resize, and format disk partitions on virtual disks. This tool is particularly useful for managing disk space on virtual machines that run on hypervisors such as VMware, VirtualBox, or KVM.

Creating Virtual Disks

One of the primary functions of fsdisk is to create virtual disks for use with virtual machines. To create a virtual disk, you can use the command fsdisk -l to list all available disks on the system. Once you have identified the disk you want to use, you can use the fsdisk -s command to create a new partition on the disk. You can specify the size of the partition and the filesystem type (e.g. ext4, ntfs, etc.)

Resizing Virtual Disks

Another important feature of fsdisk is the ability to resize virtual disks. This can be useful when you need to increase the size of a disk partition to accommodate more data. To resize a virtual disk, you can use the fsdisk -r command followed by the name of the disk and the new size of the partition. Fsdisk will then resize the partition accordingly without losing any data.

Formatting Virtual Disks

Formatting virtual disks is another common task that can be easily done with fsdisk. To format a virtual disk, you can use the fsdisk -f command followed by the name of the disk and the filesystem type you want to use. Fsdisk will then format the disk with the specified filesystem type, making it ready for use with a virtual machine.
