Dear all,

I have backup my f2fs android partition via netcat and adb.
After loosing the original partition, tried to restore it on a local
drive and access it via linux but i am encountering the following
issues:

A. trying the command

 sudo mount -t f2fs /dev/sdc1 /mnt

gives the following error

 F2FS-fs (sdc1): Failed to read root inode

B1. Tried to fsck the file system , see bellow:

sudo fsck.f2fs -a  /dev/sdc1

result:

Done.



Trying to mount it , no success, gives

Any help or advice will be much appreciated.
Keep up the great work on f2fs.

Kindest Regards

Could you try: fsck.f2fs -d 3 -f /dev/sdc1?
It seems you didn't back up the entire partition which is missing root inode
block.

Dear Kim,

Thanks for getting back to me.

I executed the command  fsck.f2fs -d 3 -f /dev/sdc1
and it gave me the following information:

It still give the same error trying to mount the partiotion.

Please advice and assist if possible.

Dear Kim ,

Regarding the question:

"Hmm, # of valid blocks is 0, which is really impossible.
 Do you have original backed up image? I think at some point the image
 was overwritten when fsck.f2fs tried to fix.
 "

I do have the original dump raw image. Please advice actions
to assist in recovering it.

I did a dd to an external drive, and from where i tried unsuccessful so far.
I use the following command

sudo dd if=mmcblk0p49.raw bs=512 oflag=sync status=progress of=/dev/sda1

mmcblk0p49.raw is the backup partitioned.

Thanks in advance

Stephanos M.

Hi,

I think you didn't back up the root inode block, since it showed zeros.
Could you try the below a bit on fresh back-up image again?

# dump.f2fs -i 0x3 /dev/sdc1
# dump.f2fs -i 0x4 /dev/sdc1
# dump.f2fs -i 0x5 /dev/sdc1

Thanks,

Quoted:
"[ASSERT] (sanity_check_nid: 362)  --> nid[0x3] ino is 0"

Look into log in the Stephanos' first report email, it looks like nat entry
of root inode was broken, if this is true, IMO, we have to add a routine to
detect such inconsistence and lookup last root inode and relink to its nat
entry.

Thanks,

Hi,

Sorry for the delay.

I figure out a patch to handle your case, w/ this patch, fsck will try to search
root inode and once it finds the target, it will relink it to its nat entry,
after this, all following check in fsck could be executed later.

If you still keep that corrupted image, could you please have a try w/ this patch?

[PATCH] fsck.f2fs: lookup and relink root inode

Thanks,

It looks running fsck two times still didn't repair the partition.

I found the output is not the same as you reported previously:

Previous:
[ASSERT] (sanity_check_nid: 362)  --> nid[0x3] ino is 0

Now:
[ASSERT] (sanity_check_nid: 418)  --> nid[0x3] nat_entry->ino[0x3] footer.ino[0x0]

Did you run fsck on original backuped image? or we have ran fsck several times
on current image before run patched fsck?

And I didn't find debug message such as "Relink root inode, blkaddr: 0x%x",
That means my patch didn't fix anything on your current image, fsck still failed
due to sanity check find another inconsistency on root inode ( which needs another
patch to fix maybe...).

Could you dump root inode info on current image?

dump.f2fs -i 3 /media/elementary/eengineering/mmcblk0p49.raw

Thanks,

Dear All,

I have made a fresh test and trial.
Please see my actions.

1. First i disk dump the original image file to a new hard drive
partition i first created (20GB)
using the command:
sudo dd if=mmcblk0p49.raw bs=4096  status=progress of=/dev/sdc1.

2. Downloaded using git and patching main.c per your instructions.

3. Make the patched f2fs-tools.

4. Put the new drive with the partition using USB, regognized as sdc , sdc1.

5. Go this result on trying the dump.f2fs
elementary@elementary:/media/elementary/mysparky/work_on_f2fs$ sudo
dump.f2fs -i3 /dev/sdc1

Invalid (i)node block

Info: checkpoint state = 4 :  compacted_summary sudden-power-off

Done: 0.024776 secs

6. then tried twice to sudo fsck.f2fs  /dev/sdc1 and on the second time i think
the patched code work due to giving :

sudo fsck.f2fs  /dev/sdc1
Info: [/dev/sdc1] Disk Model: HDWJ110

So now the checkpoing changed to
Info: checkpoint state = 281 :  allow_nocrc nat_bits unmount

from

Info: checkpoint state = 4 :  compacted_summary sudden-power-off

so i believe there is some progress...

7. Now when i try to mount the sdc1 partiotion , using dmesg i get the
following
information

[ 5553.260078]  sdc: sdc1
[ 5563.337756]  sdc: sdc1
[ 5606.821439] F2FS-fs (sdc1): Found nat_bits in checkpoint
[ 5606.965813] F2FS-fs (sdc1): Found nat_bits in checkpoint

And unfortunatly i am unable to Mount It.

Please advice on further actions and steps.. i think we are getting somewhere.

Regarding previous email the correct information is
[ASSERT] (sanity_check_nid: 418)  --> nid[0x3] nat_entry->ino[0x3]
> footer.ino[0x0]

Hi,

Thanks for the feedback. :)

> [ASSERT] (is_root_nat_corrupted: 610)  --> nid[0x3] ino is 0

Oh, if above message was printed, I guess fsck_find_and_link_root()
should be called later.

However, I didn't see "Relink root inode, blkaddr: 0x%x" message,
that means fsck_find_and_link_root() didn't find any root inode
candidates by below condition:

fsck_find_and_link_root()
...
			if (node_blk->footer.ino == sbi->root_ino_num &&
				node_blk->footer.nid == sbi->root_ino_num)
				break;

Firstly, I found I missed to call le32_to_cpu() before using footer.ino and
footer.nid field, will fix this bug in v2.

Secondly, maybe footer.ino and footer.nid in root inode were broken, I
suggest we can try below single condition or their conbinations:

- i_generation == 0
- i_namelen == 0
- i_name[] == { 0 }
- le32_to_cpu(node_blk->footer.ino) == sbi->root_ino_num
- le32_to_cpu(node_blk->footer.nid) == sbi->root_ino_num

Something like this:

			if (le32_to_cpu(node_blk->footer.ino) ==
					sbi->root_ino_num ||
				le32_to_cpu(node_blk->footer.nid) ==
					sbi->root_ino_num ||
				(IS_INODE(node_blk) &&
					(le32_to_cpu(node_blk->i.i_generation == 0) ||
					le32_to_cpu(node_blk->i.i_namelen == 0) ||
					memcmp(node_blk->i.i_name, all_zero_memory, F2FS_NAME_LEN)))) {
				printf("valid_bitmap: %d, nid: %du\n", valid_bitmap,
						le32_to_cpu(node_blk->footer.nid));
				continue;
			}

and dump all node via dump.f2fs -i nid /dev/... to verify all fields
in that inode to find which one is mostly like root inode.

> [ASSERT] (sanity_check_nid: 392)  --> nid[0x3] ino is 0

I didn't see any progress w/ my patch, as we still didn't find and repair
root inode...

Thanks,
