Hi

I get this problem running my ubi/ubifs on a partition in my system.
The error occurs when I try to move one file to a new location and there
seems to be something wrong with the file. The file contains binary data
and is 9.3MB large. Can anyone help me locate this error or point me in
the right direction?

My system is a ap7002(arch == avr32) with 32MByte SRAM, 8MByte NOR flash
and 2GByte NAND flash(ubi).

Cmd:
----
/mnt/slave # mv wpr_004.wfp ../master/data/

UBIFS error (pid 471): ubifs_check_node: bad CRC: calculated 0x582d0a64,

Hmm,

could you please enable UBIFS debugging and reproduce this. If there is
no interesting/insighting information, could you please also enable
UBIFS messages and send them. Please, glance here:

Here is some more information. On the bottom there is a general printout from the init of the ubi/ubifs on boot with dbg enabled. (Message level 0)

Here is the result from the actual move:

It looks like you indeed have corrupted data. Where the 'wpr_004.wfp'
file comes from? You wrote it previously? Or you used mkfs.ubifs?

> UBIFS warning (pid 500): mount_ubifs: 'LZO' compressor is set by superblock, but not compiled in

Hmm. Why you do not enable LZO compressor? How did you
create your file-system?

Also, did you try to enable UBIFS and UBI extra self-checks? Please,
try. Things will become very slow then, though, but this may give
some useful information.

The file is a binary file from my system. And the file has been checked for integrity before being copied over to the ubifs file system.
Wpr_004.wfp originates from a vfat partition, and was moved along with 10 other files, and then when I try to move the file back out from ubifs the read error occurs.

The partition/filsystem is created inside my system.
ubimkvol /dev/ubi0 -N wpr_slave -s 250MiB
mount -t ubifs ubi0:wpr_slave /mnt/slave
( first done format -> ubiformat /dev/mtd5 -> modprobe ubi mtd=5 )

Here are the result after enabling these two options.
How do I do cleaning in ubifs?

OK.

OK, this means that the file had not been correctly written to UBIFS.
Your NAND driver may have problems. The fact that you use NAND flash
with 4KiB page size also suggests this, because AFAIK MTD does not
really support 4KiB per page NANDs. You probably have some custom MTD
diver/modifications.

Could you please verify your NAND driver before trying to use UBIFS?
Here you may get NAND tests which should do this:

git://git.infradead.org/users/ahunter/nand-tests.git

The tests are kernel modules. Compile them properly, then just insert
them, may be with some parameters. Use modinfo to see the parameters,
or look at the source code. All tests are harmless, except of torture
test - be careful with it.

Note, these tests has not been run on 4KiB-page NANDs, but they should
work fine anyway.

Could you please tell which NAND hardware you have? Is it SLC or MLC?

I see. Basically, you have broken nodes on your flash media, which means
your files have not been written correctly for some reasons. For now I
suspect buggy NAND driver.

> How do I do cleaning in ubifs?

Well, in _normal_ situations you should not need this at all, and UBIFS
is self-recoverable. In your case you have some severe problems so you
have data corruptions which you cannot recover anyway. You may only
delete the corrupted files.

But yes, an ckfs.ubifs user-space utility would be nice to have, and we
were thinking to create it. At the moment, it does not exist.

It was correct that there was some faulty implementation of the oob/ecc handling.
This is ran on a SLC Samsung NAND flash(2GByte).

Thank you for all the help so far.

After fixing ( I think ) I ran the tests and I am adding the results from the pagetest and subpagetest.
Here where the only test with some errors.

Any hint to what to look into next would be great.

Regards

It is weird that you do not have sub-pages if this is SLC. You waste
4KiB per eraseblock because of this. Here you may find what is sub-page:
http://www.linux-mtd.infradead.org/faq/ubi.html#L_find_min_io_size

If your flash allows sub-pages, I'd recommend to support them.

No, not really. You should dig your NAND driver.
