#213235 — /usr 100%

Dear All
On my server , the "df -m" shows /usr as 100% occupied .
How can I find big size files on it to delete someone to free more space ?
Thank you

My preferred command is

du -hxd1 /usr | sort -h

- ignores other filesystem (e.g. if you mounted something on /usr/local)
- does not ignore "dot" files and directories
- sorts by size for easier reading

Be aware that /usr contains mostly files belonging to installed 
packages, so you should not remove such files by hand, but remove 
unnecessary packages instead. Exceptions are /usr/local and possibly 
/usr/src (although the latter should not be used for local compilation) 
as the whole /usr should be considered read-only.

Hi,

if your /usr is full, you can do this:

1. Add a fresh harrdrive  into your computer, format it ext2, 3 or 4,

2. mount it to some dir like /disk1

3. Then rsync all files from /usr to /disk1

4. edit /etc/fstab, so that the new harddrive is mounted to /usr

5. remount all, or reboot

6. You can then mount the OLD partition (where the old /usr resides)
and examine it.

7. Have fun and thank the developers for all the great tools in debian

Best regards

Hans

This might be awkward if the OP was installing software at the time
and things are in a partially installed state.

Assuming /usr is a separate partition, a short term fix might be to
borrow some space on another partition and move some parts of, say,
/usr/share/doc onto it. For example, here are the biggies on this
system:

15M     /usr/share/doc/sqlite3-doc
30M     /usr/share/doc/ffmpeg
35M     /usr/share/doc/python2.7
41M     /usr/share/doc/python3.5
56M     /usr/share/doc/imagemagick-6-common
73M     /usr/share/doc/debian-handbook
1.3G    /usr/share/doc/texlive-doc

101M    /usr/share/doc/texlive-doc/fonts
334M    /usr/share/doc/texlive-doc/generic
844M    /usr/share/doc/texlive-doc/latex

Then the software installation can be completed, and a decision made
on a longer term strategy.

Cheers,
David.

Am 25. Aug, 2019 schwätzte Hadi Motamedi so:

moin moin Hadi,

du -sh /usr/*

That will show you disk usage per directory in /usr/.

You can then investigate the directories using lots of space.

You might also verify you don't have a bunch of deleted files that haven't
yet been removed from the disk.

sudo lsof | grep dele

My experience with /usr filling up is that something is putting data in
there that shouldn't go there or that /usr isn't big enough to hold all
the library files. For the latter, see if there are unused packages you
can uninstall.

There shouldn't be any hidden files in /usr, but you might want to verify.

ls -la /usr/

ciao,

der.hans
