Name	Description
`--hdd <disk_path>`	Full path to the virtual disk.
`--force`	Forces the compacting operation for suspended virtual disks.
`-i, --info`	Do not compact the virtual disk; just display the information about the size the disk will have after compacting.

                     --hdd <disk_path> [--force]
prl_disk_tool resize -i, --info [--units <K|M|G|T>] --hdd <disk_path>

Name	Description
`--size`	The new size of the virtual disk. It can be set in kilobytes (`K`), megabytes (`M`, default), gigabytes (`G`), or terabytes (`T`).
`--resize_partition`	Resizes the last partition of the specified virtual disk. You cannot reduce XFS file systems (the default choice for CentOS 7 and Red Hat Enterprise Linux 7).
`--hdd <disk_path>`	Full path to the virtual disk.
`--force`	Forces the resizing operation for suspended virtual disks.
`-i, --info`	Do not resize the virtual disk; just show the size the disk will have after resizing.
`--units`	Displays the disk size in kilobytes (`K`), megabytes (`M`, default), gigabytes (`G`), or terabytes (`T`).
