If the value is preceded with a signed symbol, the filesystem is resized with respect to the current filesystem size. size can be suffixed by k,m or g to represent kilobytes, megabytes, or gigabytes respec- tively. -A device Scans the device for btrfs filesystem. -a Scans all devices present in the system for btrfs filesystem. -c Forces a filesystem sync.
