I2600 partition / has 0% free

Hi guys,

 

I have full partition error on my cluster i2600. version 13.1.3 (LTM+APM) : partition / has 0% free.

we publish an internet website with wilcard certificate

The system is continuously writing "tmp.*" files in /tmp directory.

output :

[root@xxxx:Active:In Sync] config # ls -l /tmp | more 

-rw-------. 1 root  root   2285 2020-03-12 04:59 tmp.000gWvi8JI

When i opened one the "tmp.*" file i can see it is a certificat.

after deleting the "tmp.*" files, the F5 is still writing anothers files in this directory.

Is Anyone had experience same issue ?

Please advice,

 

Thanks,

 

Leon

 

  • Hello guys,

     

    The issue was resolved after opening ticket with F5 support.

    The matter was the PKI external monitor script . this script used to write temporary certitifcate

    in /tmp for comparizon.

    symptoms of the issue was creation of /tmp/tmp.XXXX files. In order to find responsible process F5 support used auditd : auditctl -w /tmp

    and then search entries /var/log/auditd/audit.log.

    we correct the script.

    Now / partition is OK.

     

    Thanks to all of you

  • I can't help with why certificates are saved to the tmp directory, but you might get a few tips on how to clear disk space on the BIG-IP from this link (if you haven't seen it already): https://support.f5.com/csp/article/K14403

  • Hi raydakis10 ,

    I've already seen a similar problem on Devcentral, it was an iRule that creates these junk files. Do you use irules on you F5 BIG-IP ?

  • Those are just 2 KB files.... Can you please run the below and share us the output.

    df -h

    List top 20 files,

    find /var/tmp -xdev -type f -exec du {} \; | sort -rn | head -20
  • Hi Lidev,

     

    Yes i have irules on this DMZ F5 .

    Today, i'am working out of the office.

    the directory that is full is /tmp. i'll provide the output of the command ASAP :

    1. find /tmp -xdev -type f -exec du {} \; | sort -rn | head -20
