Structure needs cleaning error
Asked by
DAEHEE YOON
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_
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.
