My /storage partition became Read Only . Any ideas how to fix it?

Hi all,

I have an interesting issue today, when I woke up... My mother complained that her "TV Thingy" stopped working... I setup a LE box for her last year and shipped it across the country for her to use. I only have winSCP and SSH access to the device at this time...

I am using an Amlogic S812 device (MX3-G), with LE 8.2.5 installed.

Everything stopped working and on closer inspection, it looks like the /storage mounted partition has become RO!

cat /proc/mounts

rootfs / rootfs rw 0 0

devtmpfs /dev devtmpfs rw,relatime,size=785568k,nr_inodes=80209,mode=755 0 0

proc /proc proc rw,relatime 0 0

sysfs /sys sysfs rw,relatime 0 0

/dev/system /flash ext4 rw,noatime,data=ordered 0 0

/dev/data /storage ext4 ro,noatime,data=ordered 0 0

/dev/loop0 / squashfs ro,relatime 0 0

securityfs /sys/kernel/security securityfs rw,nosuid,nodev,noexec,relatime 0 0

tmpfs /dev/shm tmpfs rw,nosuid,nodev 0 0

devpts /dev/pts devpts rw,nosuid,noexec,relatime,gid=5,mode=620 0 0

tmpfs /run tmpfs rw,nosuid,nodev,mode=755 0 0

tmpfs /sys/fs/cgroup tmpfs ro,nosuid,nodev,noexec,mode=755 0 0

cgroup /sys/fs/cgroup/systemd cgroup rw,nosuid,nodev,noexec,relatime,xattr,release_agent=/usr/lib/systemd/systemd-cgroups-agent,name=systemd 0 0

mqueue /dev/mqueue mqueue rw,relatime 0 0

tmpfs /var tmpfs rw,relatime 0 0

debugfs /sys/kernel/debug debugfs rw,relatime 0 0

tmpfs /tmp tmpfs rw,nosuid,nodev 0 0

Any ideas on how I can fix this without having to re-flash the box?

Thanks!

Ken

I have tried

mount -o remount,rw /storage

but that doesn't work.

Use dmesg|less to check for logged errors.

It is most likely a defect file system. You can try to repair remotely, but in worst case (a real damaged file system) you stuck with a not booting system afterwards.

First identify the device: mount|grep ' /storage '. I'm assuming /dev/sda2.

Then force a fsck and reboot:

Code

e2fsck -fy /dev/sda2
systemctl --no-block reboot

Good luck.

Hey again mglae

mount|grep ' /storage '

Gives me:

/dev/data on /storage type ext4 (ro,noatime,data=ordered)

e2fsck -fpy /dev/data

Gives me:

e2fsck: Only one of the options -p/-a, -n or -y may be specified.

e2fsck -p /dev/data

Gives me:

/dev/data is mounted.

e2fsck: Cannot continue, aborting.

e2fsck -y /dev/data

Gives me:

/dev/data is mounted.

e2fsck: Cannot continue, aborting.

Looks like it may be the file system...

**mglae** · June 15, 2020 at 4:06 PM

OK, -y and -p collide.

Please use e2fsck -yf /dev/data

Awesome, that worked - thx a million!

**mglae** · June 15, 2020 at 9:05 PM

Excellent. Is your mother happy again?
