How to Resize a Virtual Disk Drive#

Note

Drives can only be increased in size; they cannot be reduced. Verify whether your guest OS supports resizing without a power cycle, particularly for Virtio-SCSI drives.

To resize a virtual disk drive within a VM, follow these steps:

  1. From the VM Dashboard, click Drives in the left menu.
  2. Select the drive to be modified.
  3. Click Edit in the left menu.
  4. Modify the drive size as desired.
  5. Click Submit.

Important Notes#

Note

If the VM configuration allows hot-plugging, the disk interface is set to Virtio-SCSI, and the guest Operating System (OS) supports it, the drive size can typically be increased without power cycling the VM.

Warning

Drives cannot be reduced in size. While partitions may be resized inside the guest OS, the disk drive itself cannot be shrunk.

Warning

Modifications to drive size will most likely require corresponding changes within the guest Operating System to utilize the newly added space.
