Structure needs cleaning error

Asked by DAEHEE YOON on 2017-11-14

I was trying to unmount the root filesystem.

my routine :
# mount root.ext4 /mnt -o loop
# cp -rf /mnt/* /media/sdcard
# sync
# umount /dev/loop0

and then i couldn't mount again.

I could only see these messages.

mount : mount /dev/loop0 on /mnt failed: Structure needs cleaning

so I ㅣlooked at the system log file

This message was repeated :

Nov 14 17:25:36 xilinx kernel: [ 539.860412] EXT4-fs (loop0): ext4_check_descriptors: Checksum for group 0 failed (43536!=14810)
Nov 14 17:25:36 xilinx kernel: [ 539.860421] EXT4-fs (loop0): group descriptors corrupted!

I read several forum posts, but I could not solve it such as fsck, mke2fs, dumpe2fs and so on.

please help me.

thank you.
