Browse Source 
Now you can specify --vfs-disk-space-total-size to set the total disk
space (default to -1)

@ -307,6 +307,13 @@ If the flag is not provided on the command line, then its default value depends
on the operating system where rclone runs: "true" on Windows and macOS, "false"
otherwise. If the flag is provided without a value, then it is "true".
### VFS Disk Options
This flag allows you to manually set the statistics about the filing system.
It can be useful when those statistics cannot be read correctly automatically.
--vfs-disk-space-total-size Manually set the total disk space size (example: 256G, default: -1)
### Alternate report of used bytes
Some backends, most notably S3, do not report the amount of bytes used.
