    @sdetweil I guess I need to delete the wolfram. I’m using an 8GB but I have’t manually changed anything so I’m surprised that it doesn’t work anymore. Maybe the logs put it over the edge.

      @tkaauf32 logs are pretty small… do the du /var/logs | sort | head thing, just on the logs folder…

        @sdetweil Permission denied. Also tried it with /logs and /log. /log says “is a directory” and the latter says permission denied

          @tkaauf32 sorry, typo

           du  /var/log 2>/dev/null
          

          may need sudo

          sudo du  /var/log 2>/dev/null

              @tkaauf32 so, all the space is used IN the /var/log folder itself, not subfolders…

              but 13040 is a tiny 0.1% WAY below the critical threshold… (if u are over 80% used, you are in trouble)

                  the du command dumps out blocks used, and does it by folder.

                  in the last screenshot, there are 13040 blocks used for the entire /var/log subtree
                  there are 6846289 blocks of space on the memory card disk volume… so, divide

                  (13040*100) by 6846289 to get the percentage used = 0.19046815%

                  in system design, if u ever got over 80% used of the total capacity (memory, cpu, disk space), the system is in danger of failure ‘soon’… (I am a long time (45 yrs) computer system solution designer)

                    @sdetweil I’m just curious how you think it went over 80% total capacity? Will this continue to happen over time? Or should i just buy a 16gig SD and it will likely solve the issue?

                      @tkaauf32 the bigger disk will help…

                      the Wolfram stuff is eating a lot of space.,

                      but I don’t see anything else really large taking a lot of space… MagicMirror is only taking about 10%
                      home folder is under 15%
