_2016-08-16_ - btrfs-size.pl is a quick little script to provide an overview of
|
|
the disk space used by btrfs subvolumes. It's comparable to
|
|
[btrfs-size.sh](https://poisonpacket.wordpress.com/2015/05/26/btrfs-snapshot-size-disk-usage/),
|
|
but is somewhat faster and has a few options to sort the output.
|
|
|
|
Honestly, it's still hard to draw any conclusions from the sizes provided by
|
|
btrfs, but sadly, [ncdu](/ncdu) is useless for snapshot-heavy filesystems.
|
|
|
|
Only tested with btrfs-progs v4.4.1.
