OpenWRT /dev/loop0 overlay question

[kdeenkhoorn]

Thanks for the help. Finally i interrupted the service on a low activity moment and swapped the USB stick in the router and transferred the files to my laptop.
Somehow

# losetup -o 455293792 -f /dev/sda2

Should be the right spot but i can't get it to mount, possibly a difference between OpenWrt and Ubuntu 24.04, i do not know.

Thanks again i've learned a lot and that's what counts.

@kdeenkhoorn

losetup -o 455293792 -f /dev/sda2

455293792 isn't a multiple of 512

so its either:
455293440
455293952

try:

losetup -o 455293440 -f /dev/sda

or

losetup -o 455293952 -f /dev/sda

I'm glad that you got your files.

Did you gather some info while you had 23.5 booted? I'm curious, what was the FSTYPE for the rootfs_data mounted at /overlay ?

Thanks
