Read-only file system

[gatesry]

Model: Roborock S5 Max Valetudo Ver: 2021.3.17 Dustbin: DustBuilder FW compiled yesterday Issue: When installing Oucher files, getting read-only file system errors that are preventing mkdir commands from executing. Through looking around, is this caused by squash file system? What other steps are needed to remount the fs?

mkdir: can't create directory '/usr/local': Read-only file system

Hello @mazak-ui ,

the strangest thing I see is that you have to create the /usr/local folder, it should already exist. Are you sure it isn't there?

Thanks

Hey @ale-rinaldi ,

Glad I'm not the only one that thinks this is weird. I'm also asking in the Valetudo telegram channel to see about this read-only fs error.

Yes, confirmed it's not there. See enclosed.

Thank you

[ale-rinaldi]

Great, let me know. I'm also asking about this on the dustcloud group if you wanna join

[gatesry]

Thanks, just joined. Send me a ping if you could.

Just an update for anyone else seeing this. Currently, with the S5M, the system is squashfs and primarily in a read-only state.

For anyone else having trouble with this, I figured out that my S5 Max writes the bump to the logfile /run/shm/NAV_TRAP_normal.log as TrapHardWalkDetector messages.

The following file is an example of how I'm using node js to send an UDP message each time there's a bump event: s5-max-oucher.js.txt

Hello @henriklied , thank you very much for your feedback! I'd like to add this recognition pattern to Oucher. Can you please send me a log captured after the robot started and made some bumps? So I can be as specific as possible in the match and avoid false positives. Thank you!

[henriklied]

Sure, @ale-rinaldi! All the lines containing TrapHardWalkDetector below from /run/shm/NAV_TRAP_normal.log are when it bumps. You also get number of bumps since the start of the cleaning session.

Hello @henriklied ,

can you please try the build at https://github.com/porech/roborock-oucher/raw/fix/17-14-s5-max-compatibility-and-ouches-on-start/oucher ? This should work.

Thank you!

[gatesry]

I'm getting my board back from DGI soon and I will test this build as well.

Hey, with : Model: Roborock S5 Max Valetudo Ver: 2022.11.0 Dustbin: DustBuilder FW compiled 23/12/2022

I can't install oucher with initd, but I can launch and run it from ssh, with small modification to config file.

I will try to edit /mnt/reserve/_root.sh to launch it from there during next week, and tell how it goes afterwards
