Bug 646616 – sys-fs/compsize - btrfs: find compression type/ratio on a file or set of files

• Status: RESOLVED FIXED
• Product: Gentoo Linux

[Description Forza 2018-02-04 23:20:52 UTC]

I think it would be good to add compsize to Gentoo. It is a small tool that shows compression statistics of Btrfs filesystems.

From the compsize GitHub page: https://github.com/kilobyte/compsize

compsize takes a list of files (given as arguments) on a btrfs filesystem and measures used compression types and effective compression ratio, producing a report such as:

[~]$ compsize /home
Processed 140058 files, 133128 regular extents (196786 refs), 80886 inline.
Type       Perc     Disk Usage   Uncompressed Referenced
TOTAL       93%       14G          15G          12G
none       100%       13G          13G          10G

Compsize version 1.1 ebuild

I wrote a (very simple) ebuild for this package.
