CentOS 7 Install

CentOS 16 Comments

I have a CentOS 7 install that seems to be filling up disk space to 100% on the root partition.

in /tmp I found files of names… systemd-private-XXXXXXXX-colord and rtkit I have never seen these files before.

there were also files of XXXXXXXXXXXXX.tmp in the /tmp folder.

Why are these files appearing? I have a number of installs and never came across this before.

  • This is a listing.

    Its the XXXXXXX.tmp directory that seem to be filling up… They have .tmp files in the directory.

    or the tracker-extract-files is also an unknown.

    What is that? how do I stop it ?


  • It looks like its these files:
    drwx—— 2 root root 8192 Aug 17 16:11 lu10398gvo2au.tmp drwx—— 2 root root 8192 Aug 17 16:14 lu3245gvrkvp.tmp drwx—— 2 root root 4096 Aug 17 16:14 lu4298gvwjcr.tmp

    That just keep growing and “many” files in each directory. Over time it fills the / root partition.

    What is making those files ? How do I stop it?


  • It’s where tracker extracts files.

    Google for “CentOS7 tracker disable”

    I suspect the lu*.tmp directories are from when tracker uses LO to extract and index documents.

    If you don’t use, or want to use, tracker, then disable tracker.


  • Hmm. was unaware of tracker-etc. what are these indexes used for?
    I can’t think of anything I do on the system that would need to know all bout some arbitrary file somewhere on the filesysystem, so why would this be useful?

    thanks in advance!


  • A more interesting question would be: Where would one go to completely STOP these files from being created / cached / logged / stored etc?

  • In Gnome 3.

    1. Got o Settings
    2. Select Search
    3. Un-check all the things you don’t want to be tracked or just turn search off.

  • My main desktop is a CentOS 7 installation, and Tracker is a very useful desktop search tool when I need to find a local file by using a keyword. I need to use it almost every a few minutes.

  • Unrelated to the disk space issues, but the systemd-private-*
    directories are created by systemd services that have PrivateTmp turned on. THose services run with a private /tmp namespace, so they can’t see the rest of the OS’s /tmp.

  • This morning. I sat down, opened my CentOS 7 laptop. It sprung back from suspension. I needed to check my project plan so I pressed the start key
    (some people call it Win key) and typed in “project plan”. Tracker Search instantly listed all documents in my home that have “project plan” in either file name and content. I pressed down key twice and then enter to open the file that I wanted to edit.

    Five minutes later, I needed to edit a project specification. I pressed the start key and typed in “MyAwesomeProject specification”. Tracker against listed all matching documents, and what I needed was usually among the top few choices.

    Another five minutes later, my insurer called and asked about some bill. I need a spreadsheet so I pressed start key and typed in “calc”. LibreOffice Calc was the first choice so I directly pressed Enter to open it. I always use this method to open any app I need, and I won’t have to touch the mouse.

    After this call, I need to schedule a meeting with a partner in London so I pressed the start key and typed in “london”. Tracker showed the current time and I could press enter to see the weather in London.

    That’s just what happened this morning.

  • Although I have to admit that the current GNOME Tracker extension is not perfect. Sometimes the search results don’t show cities. Hope the GNOME
    3.22 from RHEL 4.7 could fix this bug and bring more desktop functions.

  • Sorry for the late reply, I had to go away.

    Well, the answer I gave above is relevant:

    ‘Google for “CentOS7 tracker disable”‘

    Primarily you install the ‘tracker-preferences’ package via yum and use that to configure what tracker does.

    But in all honesty I’ve never found tracker to be intrusive after the initial scan.
