Hello,
I realized, that systemsize is 360Gb!
How can I reduce this?
Best regards,
Stefan
You can try to figure out what those DATAs are, seems like you have a huge installation, with tons of app-data 65.3 / backups 15.3 , /config 11.2 sounds also HUGE
How about your DB ?
Then you might have to look into “Docker” also , And /var/log/journal
Hi Stefan.
Click on that little symbol to the right of the word ‘belegt’ in your first picture you posted. Find it interesting?
Oh my, where to start… let me think out loud.
Your neighbour’s cat loves that spot right under the security camera to defecate each night. The ground looks undisturbed, but the gigabytes of security footage show there was movement, faithfully recorded, but the notifications were suppressed as your custom extension have animal detection turned on and it is working rather well. Your security footage was carefully selected to be retained for three months, as you had a holiday two years ago and wanted to go back and check later in case you were burgled. The retention period remains unchanged. The data files themselves have random names and are password protected and re-compressed nightly, and require a separate program to view for which you have to pay subscription fees to use.
Your AI extensions you have been experimenting with are using free CPU cycles in the background to carefully analyse the poo-ing cat videos and turn them into new cat memes and are posting them surrepticiously on the Internetz under a pseudonym to create clickbait revenue for some warmonger to support their rogue regime. The AI is keeping any that generate likes to use them to refine the content for further postings. Your neighbours cat is cute, so there are plenty of likes.
Your HomeAssistant database reorganisation housekeeping tasks have been failing due to a lack of free space, a bit like a silent passing of wind at a party - looking around - what - who - me? You are leaving doing it manually for another day, just in case the routines have changed but the documentation hasn’t been updated, or Google translate fails to translate some critical word accurately. You don’t want to lose your precious data under any circumstance, and your other backup destinations are running out of space too.
You encountered a problem, same as somebody on these forums, two years ago, and it was solved by looking closely at the error logs, so you have faithfully been keeping them in case it happens again, even though that add-on has now been re-written completely and is called an app.
You keep docker images as well as backups in three places, in case your SD Card (or SSD drive) crashes. One of the backup destinations is the very same SD Card. You keep multiple generations, in case you have to revert back to one from the year before last. You know your drive is being pounded and shortening its life. It keeps you awake at night with worry when it will inevitably fail.
Just before your Spotify subscription ran out, you decided to backup your songs to local storage using a well-pitched one-post vibed add-on that sort of worked. Part way through the Spotify download it crashed and you uninstalled it. Unfortunately, the partly downloaded songs were not cleaned up and persist to this day in their temporary folder, faithfully being backed up along with your other data, the vibe coded subroutines for cleaning up not been planned for by the newbie coder, and no testing was done before the 0.3 beta release. Of course there have not been any updates on GitHub and the one post wonder has disappeared. You closely examine the Python code for clues and discover they don’t have any relevant comments or clues where the temporary diwnloads are being stored, that part not being part of the GitHub repository that was uploaded.
Your mother-in-law visited three years ago and brought her bar heater which she left on continuously the two weeks she was in the spare room that doesn’t have heavy drapes. You are retaining the electricity consumption data, faithfully recorded every ten seconds, just in case she repeats it, and you want to prove the argument why she should be banned from visiting again. She gave the bar heater to your teenagers, who also used it on cold nights when you turned down the temperature 0.5 of a degree to save money and they noticed their room temperature setting wasn’t on ‘beach’ any more. The teenagers have since left home but the data is still being faithfully recorded every ten seconds. You keep a spare copy on MariaDb as well as SQLite and have a custom script that runs every night to export it to a csv file that your custom Graphana dashboard can display in pretty colors you can jab at while arguing your point about unnecessary electricity consumption. You can’t find that dashboard any more since last months updates, and you have forgotten which script it is, as they start with test1, test2, test 3, etc and live in a special directory you can’t get to as Samba isn’t starting again, and VS Code is hoarding system resources to the point of criticality.
You have given your teenagers admin level access, and they discovered Samba could be used to copy their favorite manga videos and porn stash to a secret folder that was encrypted rather than use space on their computers. As you were having problems with your NAS, they made a copy on your HomeAssistant drive, and changed it to the NAS when it worked again, but forgot to delete their old copy.
The teenagers took long hot showers. You decided to monitor water consumption, telling your wife it was to monitor for possible water leaks. You update the sensor every ten seconds also, as it is on the same ESP32 that you programmed in ESPHome that records your electricity. The code never worked too well, so you enabled debugging at the VERBOSE level for troubleshooting purposes. ESPHome refuses to recompile your code in Espressif format as you have custom Arduino subroutines that the original author archived years ago on GitHub and nobody has updated it. The logs faithfully record the verbose debugging data, year in, year out.
Your wife is very active on social media. A bit of an influencer actually, since the teenagers have left home. Even mastered computers since she has a little bit more time to herself. She loves to store and update recipes she has collected over the years. The WAF soared when you used Claude to make a simple screen scraper add-on to pull recipes off FaceBoob and InstaGram and store them locally where there is fast access. You are petrified of the consequences if any recipes go missing. You haven’t got around to asking Claude if they can be stored somewhere in the cloud in case somebody steals them, as your wife is writing a book, and also using Claude to collate them all, carefully sorted to her whims. Claude hasn’t been told about your NAS, so your HomeAssistant drive is the one accessible over the network from all places, even when she visits her friends and shows off the simple recipe app Claude created and she hopes to sell on Apple Apps store and Google Play to make a bit of pocket money, as well as passive income from her new book.
You tried different forms of VPN, even opening up some of your router ports in an attempt to get remote connectivity. Your teenagers demanded it so they could open the remote controlled door lock as they kept losing their house keys. You finally asked ChatGPT which offered an obscure solution which actually worked the third way it suggested, even though you don’t know why. Your system has since been silently compromised and your disk drive is currently being used to store and share unsavoury pictures across the internetz. The folders are hidden from your HomeAssistant login profile so you can’t see them using Samba from your desktop. You’ve since replaced your door lock with one that works on Matter, but are scared some of your other functionalities might stop working if you reconfigure your network even more, the shift to adding IPv6 being one that was painful, even with the assistance of AI instructions. You haven’t uninstalled the HACS integration as you have your window locks working off it as well.
Your window sensors are ZigBee, and the HACS integration you are using is flaky, so you are carefully monitoring the logs while running it in debug mode and watching the forums for clues and developments that may help.
It’s spring time, and you think it might be time to getting around to doing that update and cleanup as you are getting nervous, and the YouBoob video you were faithfully going to follow has a recent comment that somebody couldn’t get it to work for them since the big core update two months ago. You are valiantly searching for something better, but encountering lots of AI generated slop that you suspect from a gut feeling deep down is just-plain-wrong.
HomeAssistant is powerful, and flexible. Along with that great flexibility comes the severe potential to outreach your grasp. Understanding each and every nuance is even too complex for the latest artificial intelligence to grasp and keep up. There are few shortcuts that don’t come back and bite you. Each change has consequences, sometimes unanticipated.
