My CMU, when install Video Player 3.7, CMU display notifications: RootFS is Full 100%
How to fix it ?

You could try the following options (not prioritized):

a) factory reset of the MZD and afterwards installation of tweaks with ticked install option (top left corner in AIO) "apps to resoures" (tweaks will not be installed in root, but in another partition).

b) Instead of factory reset you could try to delete all tweaks via AIO, but check that the install option "apps to resources" is not ticked, as the apps should be removed from root, right?! Afterwards install the tweaks to resources.

c) You could try to delete dump files as described here in the post.

Perhaps there is more you could do, but these are my ideas so far.

You can try to delete some unnecessary font files to get more free space. For example, I have deleted some Chinese, Japanese files as below list and got more 30M free space:

yes | rm -f /jci/fonts/JP/HeiseiKakuGothW5_213_C.ttf
yes | rm -f /jci/fonts/JP/J-SC-TC-K.ttf
yes | rm -f /jci/fonts/JP/J-SC-TC-K_bold.ttf
yes | rm -f /jci/fonts/JP/MYingHei_CP949-B_C.ttf
yes | rm -f /jci/fonts/JP/MYingHeiBold18030C.ttf
yes | rm -f /jci/fonts/JP/MYingHeiC-Bold-Big5HKSCS.ttf

yes | rm -f /jci/fonts/CHN/HeiseiKakuGothW5_213_C.ttf
yes | rm -f /jci/fonts/CHN/MYingHei_CP949-B_C.ttf
yes | rm -f /jci/fonts/CHN/MYingHeiBold18030C.ttf
yes | rm -f /jci/fonts/CHN/MYingHeiC-Bold-Big5HKSCS.ttf
yes | rm -f /jci/fonts/CHN/TC-SC-J-K.ttf
yes | rm -f /jci/fonts/CHN/TC-SC-J-K_bold.ttf

@luyenok : I tried to use your usb script, but it did not start. The usb stick was recognized by the MZD correctly, it is FAT32 and it was used before for a lot for tweaks. My assumption is, that the reason is, that in file dataRetrieval_config.txt the following code has to be changed:
Your code with sd?1:
Code:
CMD_LINE=sh /mnt/sd?1/tweaks.sh
to the new code with sd*:
Code:
CMD_LINE=sh /mnt/sd*/tweaks.sh

Please use the english language, as this is an english forum. I do not want to copy other languages to the translator every time. And in your case the translator`s output is some rubbish, which I do not understand.

If you are looking for a tweak to uninstall fonts via usb - see post #7 above.

And if you can not install tweaks via usb at 70.00.335 then you have to do the serial access process ID7v2: www.mazdatweaks.com/id7 (also read www.mazdatweaks.com/serial as basic knowledge).

Thanks @luyenok for creating this usb script for removing some CHN/JPN languages to free space at the CMU (see post#7 above).
I would not recommend to use this script, if you are in the ADR/4A N region/have this firmware region, as it might happen, that you then see some symbols/icons missing.

When I deleted all these languages (EU firmware), I only missed one icon in the AIO Speedometer Tweak: the average icon (round circle with a bar through it):


Then I tested/deleted (via SSH) all the fonts one by one - after each deletion, I had to reboot. Finally I found it. The font, which is necessary for this icon being displayed correctly is the font "HeiseiKakuGothW5_213_C.ttf" in the /jci/fonts/CHN folder. The same font might be in other folders, but this one in this folder is solving the speedometer average icon issue. So this should not be deleted.


Therefore I slightly adapted the tweak of luyenok (and added my sd* improvement mentioned some posts before) - see the attached file. Just rename it (delete the ".pdf" in the name and then unzip it).

Edit: I also attached this font here. Just rename it like above. Just in case someone already deleted it and needs it/wants to install it again.

Edit 2: I deleted this script/tweak, as is deleted too many fonts - see later post for more info. I will fix this bug in the future published tweak/script.

Thank you, sir. I didn't realize that missed icons in Speedometer. I will check it and will install your new tweak. Thanks again!

Please find the new script attached (just rename it and remove .pdf of the name). This is based on luyenoks script above, but does not delete the font, which is necessary for the average icon in AIO Speedometer Tweak (see posts above). Additionally it copies this font back to the CMU (just in case it was deleted before). Have fun with it.

Edit: I deleted this script. This script was not good. I added some big fonts for deletion. And then fonts at Navigation did not work properly. I will edit it (to fix the bug) and reupload it.

Many many thanks, Tristan!! I'll test it ASAP and post the results. Cheers!

Sorry for my former mistake.
Here is the newest script, which now does not delete any fonts in the /root folder (which obviously caused my Navigation to not show any readable symbols anymore). It deletes only the large fonts shown/scripted by luyenok (in the /CHN and /JPN folders), except the one I identified being necessary for the average icon of AIO speedometer tweak. And if this font is already deleted, it will copy it back in place.

Hey @Tristan-cx5 I admit don't know much about Linux but by reading this thread I checked my system and with only one tweak(Touchscreen while moving) running my rootfs is also at 100%. How come rootfs is so small and what's eating away the space? I've ticked the option apps to resources.
I've been using i-DM you think that's the reason rootfs is filled up and Mazda hide the app to avoid a system crash?

@craz : Have you had installed tweaks before on a lower firmware version or earlier at the current firmware version? If so, I just thought about a potential solution, which might be worth a try for you:
1. Open AIO, ensure that the install option "apps to resources" checkbox is NOT ticked.
2. Mark all tweaks as red for deinstallation. Compile tweak & run it in the car (tweaks or potential hidden tweak remains should get uninstalled this way). Reboot the MZD via longpress Nav+Mute+Fav. buttons at the same time.
3. Check, like you did before, or by using my delete dumps script above (just because of the logfile info about rootfs) to evaluate, if this method freed some space in rootfs.
4. Open AIO again, ensure that the install option "apps to resources" checkbox is ticked & install your "touchscreen while moving" tweak again (if necessary - perhaps it remained).
Fingers crossed for you.

I am not a developer, I can edit existing code, but can not code full apps/scripts in linux myself. So unfortunately I can not answer your questions. Sorry. And I never used i-DM and have no experience with that (if it creates logs they have to be stored somewhere and if they never will be deleted, they also might take some space of root).

To free some space:
You could delete the fonts with the script/tweak from this thread.
And you could check via SSH for the dump folder, which also could free some space - like described here: AIO - All-In-One tweaks

NEW "DELETE DUMPS TWEAK"

Based on the findings of @issam_isl in this post (Link) [reported ~400 MB of dump files], and based on the "delete fonts tweak" of @luyenok in post#7 here (Link), I combined these two and created a "Delete Dumps Tweak". Hopefully this can help someone who has 100% full root and has some dump files, to get some space at his root partition. [most probably unfortunately wrong info].
This tweak can be installed via USB, as every other tweak (as long as your MZD is still/again capable of tweaks installation via USB). This tweak deletes the dumps (all *.bz2 files) in the MZD/CMU folder /tmp/mnt/data_persist/log/dumps/. The tweak will not check/log, if there are/were dump files. It simply executes the deletion command. If there were no dump files before, then you will not have any benefit of this tweak, but it was worth a try.

My test screenshots (via SSH connection to a CMU):
- Before (some dumps with .bz2 file extension):


- After using the tweak (no dump files in this folder anymore):


This is how the tweak looks like at the MZD display:


Download the tweak in the attachment of this post, rename it (delete the file extension ".pdf"), unzip and copy the content of the zip to a FAT32 formatted USB stick ... you should know the rest ;-)

EDIT: See post#40 for the newer version - also with logs.

Wow!! I will test it tomorrow!! I won't be able to know how many files will clean, but hey... Sure there will be at least 200 or 300MB rubbish files, right?

Thank you again, sir!!

You are welcome. I can not tell you how many dump files (MB) you might have. There are no info about how they are created or how much MB what action will generate. Only way to have a look at it before the tweak usage is to have SSH access, but then you could delete it via SSH and do not have to use this tweak ;-)

Or you do it like craz and test before and after via the installation of an AIO tweak you already have installed & compare both log files (MB and % od rootfs).

If anyone is keen and willing to extend my tweak with some sort of generator of a logfile, I would be very pleased/happy.
 
#37 ·
I guess there must be a lot of trash files in my CMU... I've installed and unistalled many, many tweaks (and many, many times) and I'm still in 56.00.230 EU (voluntarily) since 2016. Tomorrow I will install your new tweak, sure my CMU thanks you too like me, lol.

On the other hand, I would help you if I knew how to do it... Sorry for that.

Thank you again for sharing your creations.

@Vic_tormenta : If you want to wait max. 1-2 days for a version with logging, to compare the freed space (before/after), just wait until I post the next version of the tweak. I am still working on the logging function. This way you will see after the usage of the tweak in a logfile.txt at the usb stick the values of rootfs in MB "Size Used Available Use %" for the time before the deletion of the dumps and afterwards.

NEW "DELETE DUMPS TWEAK" v1.0.2

As described above in post#34, I created the DELETE DUMPS TWEAK. The below attached new version v1.0.2 creates a "logfile.txt" at the USB stick after using the tweak. And it will display in the MZD screen pop-up the total size of dump files it will delete.

Meanwhile I learned a lot about developing, but I am still a rookie. So far I understood, that the commands in the tweak delete dump files at the partition "data_persist" and not at the partition "rootfs". This is why this tweak most probably will not help you, if you have the 100% full rootfs problem. But it might help you to clean your system. And if some installed AIO tweaks are not starting/running, because of too many dump files, this tweak might help you also.

This is how v1.0.2 looks like at the MZD display:

...the shown "26.4MB" are exemplary only. The individually analyzed value of your car will be displayed. It can be more or less at your car.

Hey, Tristan! I tested your script today, it worked like a charm! It deleted around 50MB (I thought my system would have more trash files), wich it's great.

Many thanks again! Some friends tested and worked great for them too. It must be in AIO!!

Thanks for the feedback. Glad I could help. It might not be nice/perfect code, but it works :)

Meanwhile I would recommend to hit the OK button at the last page, so that the system reboots. So far there is written "not required", which technically is right, but not nice. The linux system of the MZD/CMU somehow recognizes the deletion of the files only after a reboot. That`s also the reason, why a potential before/after-comparison of the partition size/free space is not so easy to do in the script. Therefore the script detects how many *.bz2 files are there, takes the sum size and can display it. Afterwards another check is done in the folder, if there are any *.bz2 files left & writes the result to the logfile.txt. Usually there should be no *.bz2 dump files left.
 
#44 ·
I just checked the AIO 2.8.6 script ... and tadaaa ... the deletion of dumps is already included, but only if the data_persist partition is 80% or more full. Before that threshold the *.bz2 dumps are not deleted.
Man, I should have checked that before ... anyway, now with my script you can delete dump files separately and even before 80% or more full status of data_persist partition. And with my script you get displayed and logged the size of deleted dumps in total - that feature is missing in the AIO script.

NEW "DELETE DUMPS SCRIPT" v1.0.3

I had fun in improving the tweak/script, so I made a v1.0.3. It is more of a script than a tweak, as nothing gets installed.

What`s new?
  • it still deletes the same dumps - so no worries, if you used the versions before ;-)
  • optimized displaying, if no dumps are there
  • slightly optimized logging
  • optimized menu navigation
  • reboot as only exit after deletion, as only then the CMU realizes the freed space
This is how v1.0.3 looks like at the MZD display:
a) if no dumps are detected/there:

b) if process is canceled by the user input:

c) successful deletion of dumps:

Hi Tristan I've tried your script v1.02 yesterday unfortunately it got rid of 1.2mb dump files and rootfs remains at 95% full. I'll try your suggestion today. I've been using only one tweak with the same firmware since I did serial access,that's why I suspected on i-DM . What's a normal rootfs % capacity? or what do you get in your system?.

As I wrote before, my script only deletes dump files at partition data_persist, not at rootfs. That`s why the before and after value of your check for rootfs is the same. I do not know about dumps at rootfs, therefore I can not delete any there.

Example values of one of my CMUs with some, but not many tweaks installed via "apps to resources":
Filesystem..Size....Used......FREE..Use..
.....rootfs ...477.9M 435.1M 42.8M 91%..
