Then connect to ESXi shell via SSH or open ESXi shell directly on an ESXi host. Resizing a virtual disk in the ESXi command lineįirst, enable ESXi shell and Bash Console in the Direct Console User Interface (DCUI) of ESXi or in VMware Host Client. First, I will expand a virtual disk of a Linux VM on an ESXi server. You can use the command line tools or tools with the graphical user interface. There are different methods to adjust disk partition size and extend Linux partitions. In this section, I explain how to extend partitions in Linux after expanding virtual disks. Changing disk partition size may be risky if you make a mistake during the configuration process. It is recommended that you back up your VM before doing operations with disks. If your virtual machine has snapshots, delete them before you resize a virtual disk and adjust disk partition size. To be resized, a virtual disk must not have snapshots. However, you may need to reboot a VM for the operating system to detect the resized disk. Virtual disk size can be increased while a virtual machine is running. Some conditions must be met before you resize a virtual disk and the partitions on that disk.
Let’s imagine this scenario: you’ve created a virtual disk, created partitions, and installed a guest operating system on one of the partitions on that virtual disk. By Michael Bose Increasing the Size of a Disk Partition: A How-to Guide
