I tried all that but it would not go back to ro mode. I had to rebuild the sd card from scratch.
If this happens one of the pi-star scripts did not finish or hangs, causing the remount to malfunction.
Try to remount all:

Code: Select all

sudo mount -a
After that you should be able to "rpi-ro" and "rpi-rw" again.

I will try that if it happens again. Thanks.

Anyway, thanks everyone for the tips, the "Auto AP" is the solution for me and gives me a more secure feeling
on accidental power outages during mobile operation.
Unfortunately, this ended up not working for me. I turned off Auto AP yesterday on one of my hotspots. I don't leave my hotspots on, and this morning, when I powered that hotspot back on, it started up in rw mode again. It wasn't stuck; I was able to set it into ro mode with rpi-ro. But there must be something else causing Pi-Star 4.0.0-RC3 to start up in rw mode.

EDIT: After I restarted the hotspot and manually set it in ro mode, I ran the Pi-Star Update script. This time it did get stuck in rw mode. I tried sudo mount -a, but that didn't help. I ran the Pi-Star Upgrade script, and that didn't help. I ran sudo reboot, but it didn't successfully reboot, so I powered off and back on. It started up in rw mode, but I was then able to manually set it into ro mode using rpi-ro.

I also disabled Auto AP mode on my 3B running 4.0 RC3 and it is still stuck in read/write mode.

I installed ‘lsof’ to show which files were held open preventing the mount going back to read-only and the list was pretty long!

I am going to reimage the card and see if I get different results. If not, I’ll post the output from ‘lsof’.

UPDATE
Now a few days of checking and all of my hotspots still in "ro" mode:
  • Can rpi-rw / edit some file / rpi-rw without trouble.
  • Can do nightly updates without trouble.
  • Can do manual update/upgrade without trouble.
  • Guess i'm lucky
One thing: my Pi's are always powered on.

Keep y'all informed if anything changes, and meanwhile following the thread.

Pi-Star AutoAP has been patched so that it no longer keeps the disk in RW mode, you will need an update and a reboot if you want to test it with the AutoAP active.

Thanks Andy !

Tested it with all my hotspots now AutoAP on and they are all running fine.
The AutoAP works as usual, and for now the "rpi-rw" and "rpi-ro" seem to function ok.
Tested it manual over SSH with PUTTY doing rpi-rw/edit a file/viewed logfile/rpi-ro.
Also tested it from Pi-Star using "update", which ended ok and made the OS "ro".

Hello,

I’ve noticed that there’s a regression of this issue in Pi-Star 4.1 RC3 to RC5.

I know there was a proposed workaround initially that didn’t work, then it seemed like the issue was fixed in the 3.x days with a patch to AutoAP but it’s back. Big time!

I need to try disabling AutoAP to see if this is simply a matter of the patch not being included in 4.1 but I’m out of town and will not be able to try it until I get back home this coming weekend.

I’m not alone in noticing this issue. I just replied to a post on “Pi-Star Support Group” on Facebook as someone asked about this same issue there.

This issue is one of the leading causes of instability on Raspberry Pi in general and Pi-Star is one of the few solutions I’ve worked with that makes a converted effort to ensure the filesystem is read-only during traditional operational state.

Please look into this. It would be great to get a root cause analysis and a fix checked in that resolves it.

If there’s any way I can assist in providing logs or other datasets to help with debugging the issue.

Before people beat me up on this - yes, I know it’s free software and that Andy and any other contributing developers are volunteering their valuable time.

Thanks so much!!!

Best regards,

-JeffH

Disabling auto ap doesn't work. After an update you get /mount point busy or somesuch.

Out of curiosity have you rebooted since disabling AutoAP?
