Hi everyone,
Please help me out, my OpenWrt's file system became read-only after a single power outage. Currently router works fine (with all my settings as on the moment outage happened) but I can't save and apply any changes to settings via LuCi anymore.
I'm running vanilla OpenWrt 19.07.5 (openwrt-19.07.5-ramips-mt7621-xiaomi_mir3p-squashfs-factory.bin) on Xiaomi Mi Router Pro (R3P, ESMT NAND, no bad blocks) without any additional packages. I cannot reinstall OpenWrt because my laptop doesn't have Ethernet port anymore. And I'm looking for a proper solution to be able to deal with this in case it happens again.
Here's troubleshooting data:
/$ df -Th
Filesystem Type Size Used Available Use% Mounted on

tmpfs tmpfs 250.6M 88.0K 250.5M 0% /tmp

/dev/root on /rom type squashfs (ro,relatime)
proc on /proc type proc (rw,nosuid,nodev,noexec,noatime)
sysfs on /sys type sysfs (rw,nosuid,nodev,noexec,noatime)
tmpfs on /tmp type tmpfs (rw,nosuid,nodev,noatime)
/dev/ubi0_1 on /overlay type ubifs (ro,noatime,ubi=0,vol=1)
overlayfs:/overlay on / type overlay (rw,noatime,lowerdir=/,upperdir=/overlay/upper,workdir=/overlay/work)
tmpfs on /dev type tmpfs (rw,nosuid,relatime,size=512k,mode=755)
devpts on /dev/pts type devpts (rw,nosuid,noexec,relatime,mode=600,ptmxmode=000)
debugfs on /sys/kernel/debug type debugfs (rw,noatime)
As far as I can tell there's plenty of free space available in /overlay. I suspect the problem is in /dev/ubi0_1 on /overlay type ubifs (ro,noatime,ubi=0,vol=1).
I'm able to successfully mount /dev/ubi0_1 as read-write using this command
mount -o rw,remount /dev/ubi0_1
and change/edit files (like /etc/config/wireless contents) via SCP/SSH since /dev/ubi0_1 becomes read-write in mount report. However after reboot the edited files are back to their pre-edit state!
If I click save and apply any changes via LuCi after successful execution mount -o rw,remount /dev/ubi0_1, the file system becomes read-only and no changes are saved! Using SSH I can see /dev/ubi0_1 on /overlay type ubifs (rw,noatime,ubi=0,vol=1) becomes read-only /dev/ubi0_1 on /overlay type ubifs (ro,noatime,ubi=0,vol=1) after reboot.
As far as I could figure, file system becomes read-only of OS marked it as not clean (dirty, unsafe, corrupt) after power cut. So user has run file system integrity check and fix error to mark file system as safe to operate (clean). This is typically done via fsck. I've created a VM (with KDE neon guest) and tried running fsck /dev/ubi0_1 via SSH from Konsole. But no luck, the command is not found (well, probably because it is not present in my OpenWrt installation).
Maybe there's another way to mark file system as safe somewhere manually without fsck (likely f2fsck for my router)?
Or I may be completely wrong and this has to do with UBIFS suddenly read-only issue (but my /proc/mounts file is emply so no clues there) as dmesg says UBIFS (ubi0:1): recovery needed & UBIFS (ubi0:1): recovery completed during boot and after that (in the very end of dmesg):
[ 36.510035] UBIFS error (ubi0:1 pid 1328): 0x801b3f18: failed to read inode 1865, error -2
[ 36.510093] UBIFS error (ubi0:1 pid 1328): 0x801afe90: dead directory entry 'iw', error -2
[ 36.510108] UBIFS warning (ubi0:1 pid 1328): 0x801b6ef0: switched to read-only mode, error -2
To make things worse, I believe my router was running without power cuts previously, so my issue may be related to the thread UBIFS fails to mount on second boot (without solution). And as far as I googled, there's no fsck for UBIFS, a different tricky system integrity check method should be utilized, here's result:
/$ find / -type f -print -exec cat {} + > /dev/null
find: /overlay/upper/usr/sbin/iw: No such file or directory
cat: can't open '/proc/sys/net/ipv4/route/flush': Permission denied
cat: read error: I/O error

cat: can't open '/proc/sys/vm/drop_caches': Permission denied
or
/$ find . -type f -exec pv -N {} {} \; > /dev/null
find: ./overlay/upper/usr/sbin/iw: No such file or directory
find: ./proc/12323: No such file or directory
iw file is not there. And I've tried running mount -o rw,remount /dev/ubi0_1 and then manually copying /usr/sbin/iw to /overlay/upper/usr/sbin/iw but I get error No such file or directory, same with 12323 directory:
/$ cd /proc /proc$ mkdir 12323 mkdir: can't create directory '12323': No such file or directory
I have tried rebooting and cutting power multiple times, the UBIFS errors are same every time.
Please help me out, Sergey Brin called me and told I've already broken Google while searching for solution.
Kind regards,
bananakid
P.S. I'm providing dmesg data, but it's probably irrelevant:
