Increasing the Virtual Disk Capacity

If you find that the capacity of your virtual machine's hard disk does not fit your needs anymore, you can increase it using the prl_disk_tool utility. For example, you can execute the following command to set the capacity for the MyVM-0.hdd disk to 80 GB:

# prl_disk_tool resize --size 80000 --hdd /vz/MyVM.pvm/MyVM-0.hdd/

Operation progress 100%

This command adds additional disk space as unallocated space. You can use standard means (e.g. the Disk Management tool in Windows-based virtual machines) to allocate this space by creating a new partition or expanding an existing on.

At the same time, you can use the --resize_partition option to automatically add additional space to the last partition on the virtual disk:

# prl_disk_tool resize --size 80000 --hdd /vz/MyVM.pvm/MyVM-0.hdd/ --resize_partition

Operation progress 100%

When increasing the disk capacity, keep in mind the following:

• You cannot increase the capacity of a virtual disk if the virtual machine using this disk is running.
• The virtual machine using the virtual disk you want to configure must not have any snapshots. Otherwise, the operation will fail:

  # prl_disk_tool resize --size 68000 --hdd /vz/MyVM.pvm/MyVM-0.hdd/

  This disk has one or more snapshots and cannot be resized.

  You need to delete snapshots using the pctl tool before resizing the disk.

  In this case, you should delete all existing snapshots and run the command again. To learn how to delete virtual machine snapshots, refer to Deleting a Snapshot .

• The capacity of an expanding virtual disk shown from inside the virtual machine and the size the virtual disk occupies on the server's physical disk may differ.
