BTRFS-Size

A script that will print out a list of BTRFS subvolumes along with their size in megabytes and their name

You will need to enable quotas first. Run this command as root: btrfs quota enable /

For more information check out this blog entry.

To invoke just run:

./btrfs-size.sh

To run on a directory outside root run:

./btrfs-size.sh /path

Example output:
