I've had several cases where our MLC NAND flash appears corrupted in
such a way that one of three UBIFS volumes can not be mounted due to
"failed to recover master node". I haven't been able to reproduce the
problem, but we've had at least 5 incidents where this has occurred.
(A partial capture from one of the failures is below.)
I'm starting to investigate this problem and don't know if this is a
UBIFS/UBI problem or a NAND driver problem. I'm starting the process
of back-porting the latest UBIFS code to our 2.6.29 kernel - hoping
that new UBIFS code will solve the problem. However, this may also be
a driver problem and I wonder if I also need to update that driver
(pxa3xx_nand). Any suggestions for debugging this problem?
Thanks,
twebb

Please, enable all debugging messages, mount this flash again, and send
the messages.

And BTW, it is a good idea not to erase/re-flash this device if you want
to fix this problem.

I have enabled...
CONFIG_MTD_UBI_DEBUG=y
CONFIG_UBIFS_FS_DEBUG=y
Should I enable CONFIG_UBIFS_FS_DEBUG_CHKS ?

You may enable checks as well, but I was talking about messages. And
enable them before mounting the corrupted flash, not when you are trying
to reproduce this.

I've attached a log file that captures the problem I'm seeing. The
log includes failures on 2 of 4 UBIFS volumes that are part of a
single MTD device (and shows the other 2 volumes being
mounted/umounted without error).
It appears from the log that the problem is associated with "corrupt
empty space" which can be seen in the log at lines 28, 313, 347, and
359. Could this be HW ECC failing to correct bit errors on reads?
Any suggestions on what this problem would be helpful.
I'm using MLC NAND (Samsung K9LBG08U0D) on a Marvell Armada PXA16x.

twebb

twebb, you did not enable debugging messages. But it looks like they are

Yes, HW fails to correct bit errors. Why these errors are there - this
it the question. May be MLC-related. You need to debug this. Or send me
your board, I can try to take a look
Did you enable UBI extra self checks?

I config'd kernel with...
CONFIG_MTD_UBI_DEBUG=y
CONFIG_UBIFS_FS_DEBUG=y
Did I miss something else?

It does appear to be an MLC-related problem - either read or write
disturb appears to have made an "empty" page not really empty. Would
UBI extra self checks handle this situation? I'm not familiar with
what the extra checks do - I'll look in the code.
Since read/write disturb errors are a trait of MLC, I'm curious how
others are dealing with this condition? ECC can't correct for it
because it's supposed to be a blank page, implying no ECC is present.
So if a read or write disturb occurs and the blank page is no longer
blank - how does driver and/or UBI/UBIFS handle this? Seems that the
remaining "good" block data would have to be moved to another LEB and
the current block somehow marked as dirty.

ubi_leb_change() could do this.

Our power off tests causes this sporadic error too (ubifs_recover_master_node: failed
to recover master node).
We use kernel 2.6.29 with the git-patch (from 3/2010) for 47MB NOR flash partition.
I tried to find with debugging the error reason.
The recover of the master_node reads the master_node1 and master_node2.
The master_node1 was emty.
The error was detected in:
int ubifs_recover_master_node(struct ubifs_info *c)
....
if (mst1) {
......
} else {
if (!mst2)
goto out_err;
/* 1st LEB was unmapped and about to be written, so there must
* be no room left in 2nd LEB. */
offs2 = (void *)mst2 - buf2;
if (offs2 + sz + sz <= c->leb_size)
goto out_err; !!!!!!!!!!!!!!!!!!!
mst = mst2;
}
I checked the values of the compare "if (115712 + 512 +512 (=116736) <= 130944)".
I skipped this error for test purpose. The master_node was recovered. I saw no problems
with the FS. I was not able to follow this check.
I was able to provoke this error manual.
My UBIFS use LEB:1 for the first master_node and LEB:2 for the second.
I searched the LEB:1 and deleted this sector.
The following loading and mounting causes the error.
A ignoring of the error causes a successful recovery.
I used 15 MB and 47 MB NOR flash partitions for this tries.
The 15MB partition flash checks the error in the compare "if (9216 + 512 +512 (=10240)
<= 130944)",
These values are independent to the PEB of LEB:1 and LEB:2 and independent to the free
space of the FS.

Reinhold

But how this situation could happen? UBIFS updates the master nodes by
writing them one-after-another, till there is space to write. And when
thee there is no space, it unmaps the 1st LEB, writes the master node,
then unmaps the 2nd LEB, and writes the master node.
How could we end-up with a situation when the 1st LEB is empty, while
the 2nd has room for more master nodes? This sounds like the problem is
somewhere else, may be in UBI? Do you have any explanation?
I mean, the only code-path which changes the master nodes in UBIFS is
'ubifs_write_master()'. If this function is the only one which, your
situation cannot happen.
Did you try to enable recovery debugging messages? Did you look what is
in your LEB2 after 'offs2' ? Are there 0xFFs? I think if you enable
recover debugging, UBIFS will print a hexdump? Or you can just inject
some 'dbg_dump_node()' or 'print_hex_dump()' calls.
I mean, if you just remove that check, you may hide the real problem.
> I was able to provoke this error manual.
Well, yes, you break UBIFS assumptions about which kind of errors it
fixes. As I answered in another e-mail today to twebb - UBIFS fixes only
problems caused by power-cuts. If it sees a problem which cannot happen
because of a power-cut, it panics. So, as I explain above, your issue
should not happen due to power cuts. But it happens, which means there
is probably a bug somewhere else.
Reproducing the problem and dumping the flash contents in the end of
LEB2 would be interesting.
