It is currently possible to have swift-recon report on disk usage by two means:
swift-recon -d OR
swift-recon --all (which includes -d)

Disk usage provides two options:
--human-readable to provide usage in GB rather than bytes
--top <integer> to list devices with the most usage

These options are currently usable when using -d but not --all.
This is because the options are not passed to disk_usage when using all:

Versus when using -d:
