### 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)

Some backends, most notably S3, do not report the amount of bytes used. Some backends, most notably S3, do not report the amount of bytes used.
