Your JFFS2-partition seems full and overlayfs is mounted read-only.
Please try to remove files from /overlay/upper/... and reboot!

It's telling you exactly what to do.
Either something didn't load properly upon a reboot causing JFFS to be in RO when it needs to be in RW
OR
remove files to add space to /overlay/upper/....
I have space, how to switch to RW, I reboot and it is still the same
Well in Linux if there's an error on boot it goes RO
Check /etc/fstab to make sure they're not set to RO
cat /etc/fstab#nvme0n1p2 errors=remount-ro 0 1
#nvme1n1p2 errors=remount-ro 0 1
<file system> <mount point> <type> <options> <dump> <pass>
# / was on /dev/nvme0n1p2 during installation
UUID=eb810a54-202c-4b64-82f7-24f49196f2d6 / ext4 errors=remount-ro 0 1
# /boot/efi was on /dev/nvme0n1p1 during installation
UUID=7E42-9EC0 /boot/efi vfat umask=0077 0 1
/swapfile none swap sw
If you would like remount it to read-write, use mount -o remount,rw /
If you dig through syslog / dmesg there might be a reason why it's mounted in RO.
at the end i see that;

Peacefuleight:
nvme0n1p2
I would do a "dmesg | grep -i nvme" and see why it's being remounted. Something is triggering it to be dismounted for some reason as the typical boot period is less than 15-20 seconds and 3-4 minutes into running shouldn't be producing an error to force a FS remount.

Looking at the re-mount line though might not be what we're looking for since I'm seeing it in my output as well but, not restricted to RO on my OS partition at all.
Might be time to do a fsck on the drive just to see if anything comes back as an error causing RO to be invoked.
It's a bit odd though I'm seeing the remount message on my primary drive and not my secondary that I rsync to. However looking at the timestamps it's only ~30ms before it's issuing the re-mount message.

What kind of system is this?

I have zorin os with 5.16 kernel. an it is on my new samsung 970 evo plus nvme ssd
Interesting indeed.
Drives are showing in RW but OWRT says RO.
Container?
BTW that EFI partition can be knocked to 50MB if you need the space or don't want to waste it on emptiness. I had to convert to EFI and gave it as small of a spot as possible without the OS getting angry about it. 50MB is still too much but, that's what it is.
