try on your machine

The command lvresize is used to resize a logical volume in a Linux system.

Here's an explanation of the options used in the command:

--size -${120G}: Specifies the new size for the logical volume, which is calculated by subtracting 120 gigabytes (120G) from the current size. The minus sign (-) before ${120G} indicates that the size is being decreased.
--resizefs: This option instructs lvresize to also resize the file system within the logical volume after resizing it. This ensures that the file system can utilize the available space.
${volume_group}: This is a placeholder for the name of the volume group that contains the logical volume you want to resize. You need to replace ${volume_group} with the actual name of the volume group.
${logical_volume}: This is a placeholder for the name of the logical volume you want to resize. You need to replace ${logical_volume} with the actual name of the logical volume.

To summarize, the command lvresize --size -${120G} --resizefs ${volume_group}/${logical_volume} resizes the specified logical volume by reducing its size by 120 gigabytes and also resizes the file system within the logical volume to utilize the changed size.
