Hello,

Best advice is to follow SK60080 and use du command (disk usage) - Disk space tips and tricks for SecurePlatform / Gaia / IPSO / Linux OS

Most of the time most space is due to logs ($FWDIR/log) and previous JHF.

Hope it helps!

Glad I could help, another advise is to set up a cron job that clean your logs each X days, you can even make the script to upload them to a ftp/sftp.

It appears that / is the mount point that is filling up. The quickest and safest ways is to clear up unnecessary files in /home.

If you run a du -hs /home/*     then you should see the user with the largest home directory and then remove unnecessary files like cpinfos, database exports, etc.
