      Pre-2.7.2/23.09: Only install packages for your version, or risk breaking it. Select your branch in System/Update/Update Settings.
      When upgrading, allow 10-15 minutes to restart, or more depending on packages and device speed.

        Connect to the console. Run item 8 (Shell). Run this command and see where all the files are:

        du -Pshx /*

          1. Take a full Backup in the WebGUI
          2. Reinstall 2.4.4-p1 with some more space
          3. Online Update to 2.4.4-p2
          4. Restore your Backup

            Thank you for your reply @Rico
            If i reinstall, Can I use my backup of WebGUI completely without any changed? Because I am afraid that If I restore backup of WebGUI, i want to get back my all settings all rules without any error.

                It looks like everything is in /var where the logfiles are stored. I run a VM with a 4GB disk and only have 56MB there. Take a look at Status/System Logs/Settings and see if you are logging all traffic that is allowed to pass. That would fill things pretty quick. If so, clear this check box and reset the logs to get the space back.

                After that, I would check your rules and see if you have some excessive logging turned on there. Maybe someone created or was testing a rule and forgot to turn logging off. Hope this helps.

                  pfSense uses circular logs, so unless he has increased the log file size setting considerably none of the logs from the base system will fill up the disk. This is more likely, and like @teamits suggested, a package going rampant.

                    du -Pshx /var/*
                    
                     du -Pshx /var/log/*
                    

                    to track it down.

                                  @FroLien Looks like it's your Squid cache (I think so anyway, I don't run Squid). I think you just need a larger disk. Can you expand it? Maybe to 20GB?

                                      I deleted logs folder from /var/squid
                                      After I deleted it, i got over half of free space.

                                      alt text

                                      I deleted it with this command.
                                      rm -r /var/squid/logs in shell (8)

                                        @FroLien It's not the logs, it's the cached info that Squid serves (images, etc, etc) so they don't have to be retrieved again from the Internet. How much disk space do you have allocated for Squid in settings?

                                        EDIT - Well OK then... :) It was the logs... I don't have Squid installed, so I don't know what the file structure is at that level. I still think I'd make your disk about 10-20GB...
