Hello,

My Nethserver is tranquilly install on a 160 Gb disk… When all the Nethserver space is hardly 3gb…
Since I made my first Time Machine backup, simply 260 Gb… The Disk Usage look like this:

Can I configure the Disk Usage module to ignore /opt ?

@Jim where are you?

At work…

@Nas, I’m not sure if you’re addressing what he’s asking.

@Jim, you want to exclude /opt from the disk usage calculation, right?

Nas · September 30, 2015, 7:47pm

Sory i see what he mean

I would imagine you add something to /etc/e-smith/events/actions/nethserver-duc-index for exclusions.

That’s the file that’s run with the daily cron job to recalculate disk usage and I believe it’s just rerun manually when you click the update button in the web gui.

edit: found it! change this line:

/usr/bin/duc index $INDEX_DIR --database=$DUC_DB

to

/usr/bin/duc index $INDEX_DIR --exclude=opt --database=$DUC_DB

Reference this for more cool stuff you can do!

duc(1) -- index, query and graph disk usage
===========================================

## SYNOPSIS

`duc` <subcommand> [options]


## DESCRIPTION

Duc is a collection of tools for inspecting and visualizing disk usage. 

Duc maintains an indexed database of accumulated sizes of directories of your
file system, and allows you to query this database with some tools, or create
fancy sunburst graphs to show you where your bytes are.

Duc scales quite well, it has been tested on systems with more then 500 million
files and several petabytes of storage.

Edited to correct lines to edit. Thanks @Nas!

@Adam have you test those feature ?

Adam · September 30, 2015, 8:22pm

Yes sir. Worked great for me.

duc index /var
Indexed 22759 files and 4779 directories, (1.8GB total) in 0.74 secs.

So You are Wrong @Adam

option that should be changed :

 # directory indexing
/usr/bin/duc index $INDEX_DIR --exclude=var --database=$DUC_DB

Nas · September 30, 2015, 8:30pm

and only after it it make right graphs

Adam · September 30, 2015, 8:37pm

Good catch! You’re totally right! … except he wants to exclude /opt, not /var…
