I'm willing to bet you have an 8GB card or better, and yet your screenshots show that you've used only 1.8GB but only have 22MB remaining. That's because your SD card wasn't expanded after having Stratux flashed (loaded) onto it. The Stratux software, including the underlying operating system, is skrunched down to a bare-bones size so that it takes less time/bandwidth to download the complete image. This is true for most all software packages and is expected. The drawback in this case is that once that image is loaded onto your card, it's still the same small size, regardless of what size SD card you have. That's why your system is reporting itself as full, when in fact there's 6 more GB available - the system just needs to be told that it's there.
You've refused my advice here before that would've fixed your problem. I'm going to assume you'll ignore it again, but I'll spell it out anyway in case it helps someone else. There's actually several ways to solve your problem and I'm going to spell out what I think will be the easiest and safest.
First, you'll need an ssh client (ssh = "Secure SHell" - an encrypted way to talk from one machine to another). It's how you'll "talk" to the underlying Raspberry Pi software. You'll need to download the ssh client onto a computer that can later connect wirelessly to the Pi, such as a Windows laptop or Android phone/tablet. If you only have CrApple products then I can't help you - read my instructions and figure out how to do the same thing on a CrApple.
On Windows, download/install PuTTY: https://the.earth.li/~sgtatham/putty/latest/w32/putty.exe
On Android, download/install JuiceSSH: https://play.google.com/store/apps/de...cessh&hl=en
(both are free and widely used)
After installation, connect your device to the Stratux wifi and open up the ssh client. Figure out how to connect the client to the Stratux - it'll involve the Stratux's IP address of 192.168.10.1, and a port of 22. (Google if you get stuck, or look for a YouTube video). It'll give you a large "Sky is falling!" screen about "The keys have changed!" or some such message. This only means that the ssh client has never seen this particular device (Stratux), and wants to be sure you know what you're doing. Pretend you do, and accept the risk. You'll then be asked to give a user id - type in "pi" lowercase, no quotes. Then it'll ask for a password - type in "raspberry", all lowercase and no quotes. At this point you'll see a glorious "Welcome to Stratux!" screen, and the curser will be at a text prompt at the bottom. Type in "sudo raspi-config" and hit enter. find the option that mentions expanding the file system - I think it's the first one. Expand the file system. The screen will flash a few times and you'll get a message that says the file system will be expanded on the next boot. You're thru with raspi-config - use the tab key to exit. [EDIT: If you see an option to "Reboot Now", do it and you're done! Otherwise, continue --->] Back at the text prompt, type "sudo reboot" ("sudo" is the Linux equivelent of saying "Mother may I?"). Screen activity will stop and you can close the ssh screen/app - it's done its job. The Stratux system will reboot, and when it comes back up the Status page will verify that you now have access to the whole 8 or 16 or 32 or whatever Gigabytes.
This is all from memory so a step or two may be slightly off. Google is your friend.
Once you succeed, remember how to ssh in and get to the text prompt. Watch the Stratux Status page over time and when the disk starts to reach 6-7GB (now it'll take forever to fill up unless you're running it 24/7), ssh into the Stratux and type "sudo rm -f /var/log/stratux*". This'll delete any/all logs associated with Stratux and the clock can start over again.
Hope this helps somebody
