LibPATA code issues / 2.6.15.4

LibPATA code issues / 2.6.15.4

[Justin Piszcz]

Jeff,

I'd have to double check but I do not recall getting these errors before 
the pass-thru code was introduced in 2.6.15, I also was not running the 
smart daemon until 2.6.15 for SATA drives as it was not supported.

I had a few issues before that I posted to LKML, those were due to too 
many SATA devices etc, everything is back to normal for the most part.

Speed, etc, all is well again, almost...

/dev/sdc:
  Timing buffered disk reads:  154 MB in  3.02 seconds =  50.97 MB/sec
/dev/sdc:
  Timing buffered disk reads:  162 MB in  3.00 seconds =  53.94 MB/sec

The only issue I have is when I copy a lot of files to a WD 400GB drive I 
these pesky errors in dmesg:

  ata3: translated ATA stat/err 0x51/04 to SCSI SK/ASC/ASCQ 0xb/00/00
  ata3: status=0x51 { DriveReady SeekComplete Error }
  ata3: error=0x04 { DriveStatusError }

Yet, everything copied (226GB) or so to the 400GB drive without a single 
I/O error that I am aware of.  So my question is, why do I get these 
errors in dmesg if they are not critical?

Thanks,

Justin.

I wonder if the FUA logic is inserting cache-flush commands
and perhaps the drive is rejecting those?

Jeff, we really ought to be including the failed ATA opcode
in those error messages!!

If such a thing were available as a patch then I too would apply it and
hopefully could provide useful feedback.

I would like to try the patch too, if available.

I got these errors when nothing (apparent) was going on.

Something like this:  (for 2.6.16-rc3-git2, but should be okay on 2.6.15 also).

Untested:  include the original SCSI opcode in printk's for libata SCSI errors,
to help understand where the errors are coming from.

Thanks, I will reboot later tonight and see what type of error codes it 
gives me.

Untested at present, as I was hoping to hear
back from one of the original problem reporters
after they tested it.

I have patched the kernel and rebooted it with your patch, but, of course, 
with my luck it has not given me any errors since, even when repeating 
major file copies, bonnie++ and iozone!! :(

Can you tell from this what they mean?

This is with 2.6.16-rc3, your patch, and running nine Maxtors disks
over onboard nForce4 and MV88SX6081 8-port SATA II PCI-X Controller (rev 09).

for i in `seq 10`
do dd if=/dev/zero of=bigfile.$i bs=1024k count=10000
done
md5sum bigfile.*

The errors mostly seem to happen during the md5sum (not during the dd).

I do not see data corruption or slowdown.

I do need a chunksize of 512k for the raid5. With anything lower (I tried
the default 64k, 128k, 256k, 512k and 4096k) I get data corruption and
the errors reported in:
http://marc.theaimsgroup.com/?l=linux-ide&m=114016903530007&w=2

Thanks!

SCSI opcode 0x2a is WRITE_10, so the errors are being reported
in response to the writes to bigfile.$i.  But these are different
from the previously reported error status values -- I wonder why
it's getting "Busy" back as a status here ??

Ah, my bad then.

Well, as I wrote, I am not the original reporter whoms thread you
responded to with your patch. I just thought I could use it to get
better errors messages for my bug reports.

I am using the sata_mv driver, which is beta. That might explain why it
behaves not totally as expected in your eyes. I have no clue anyway :-)

I hope my reports are of any use to Jeff wrt the sata_mv driver.

Thank you for your response.

Ahh.. that's useful to know.  I expect to be taking a long hard look
at the innards of the sata_mv code in the near future, so whatever is
wrong here just might get fixed soon.

I'm sorry for omitting that information in my previous mail.

Consider me your happy and willing patch test victim :-)

I can easily reproduce data corruption with sata_mv.

FWIW, I like this card very much. It is cheap, seems to perform well,
and Marvell seems to be Linux friendly, providing the docs (according to
http://linux-ata.org/sata-status.html#marvell).

I'm not subscribed to linux-ide, but am to linux-kernel. If you post it
there (or cc me) I'll see and try it.

Re: LibPATA code issues / 2.6.15.4

[Justin Piszcz]

I have reproduced the error with the patched kernel!

Here it is:

[263864.109854] ata3: translated ATA stat/err 0x51/04 to SCSI SK/ASC/ASCQ 
0xb/00/00
[263864.109861] ata3: status=0x51 { DriveReady SeekComplete Error }
[263864.109866] ata3: error=0x04 { DriveStatusError }

Here is how I got it to error:

$ for i in `seq 1 1000`; do dd if=/dev/zero of=file.$i bs=1M count=$i; 
done

Now, how to fix? :)

Thanks Mark - I've finally gotten this patch applied.

With smartd disabled and no smart commands issued, a readonly badblocks
scan of /dev/sdb2 shows no problems and now gives:

hundreds of times.

and during boot I can get:

Subsequently a
 smartclt -data -a /dev/sdb
shows no errors.
So could this be a faulty disk that smart shows is OK and shows no read
or write errors?

The other problem I noticed was that
 smartctl -o on -data /dev/sda
still just gives:

I get similar problems for all the drives under both sata_sil and sata_via.

Nope.. patch not present, as otherwise the line above would have
read something like this:

 > [263864.109854] ata3: translated op=0x21 ATA stat/err 0x51/04 to SCSI SK/ASC/ASCQ 0xb/00/00

So we didn't get the extra info since the patch wasn't present.

Cheers

The kernel is patched, if you did not get what you wanted maybe the patch 
does not work in some instances or there is a bug?

You may have patched a kernel source with Mark's patch, but you are
very clearly not running a kernel build from that patched source.

As can be seen from (for example) this bit from Mark's patch

 translate_done:
-       printk(KERN_ERR "ata%u: translated ATA stat/err 0x%02x/%02x to "
-              "SCSI SK/ASC/ASCQ 0x%x/%02x/%02x\n", id, drv_stat, drv_err,
+       printk(KERN_ERR "ata%u: translated op=0x%02x ATA stat/err
0x%02x/%02x to "
+              "SCSI SK/ASC/ASCQ 0x%x/%02x/%02x\n", id, opcode,
drv_stat, drv_err,
              *sk, *asc, *ascq);

the patch changes the text being printed. In this case the text
"ata%u: translated ATA stat/err ..." is changed into "ata%u:
translated ATA stat/err ..."

And if we look at the output you posted :

> >> Here it is:
> >>
> >> [263864.109854] ata3: translated ATA stat/err 0x51/04 to SCSI SK/ASC/ASCQ
> >> 0xb/00/00

That string is clearly from an un-patched kernel as Mark also pointed
out in his reply to you.

..

Mmmm.. okay, it's happening due to a SCSI READ_10 opcode,
which means it isn't being triggered by any of the FUA stuff.

But there's still no obvious reason for the error.
The drive is basically just saying "command rejected",
and libata-scsi is translating that into "medium error"
for some unknown reason.

Unfortunately, the design of the current libata is such that
we no longer have access to the actual ATA opcode that was rejected.
It gets overwritten by the returned drive status on completion.

So.. I need to generate another patch for you now, to save/show
the real ATA opcode that was used to cause the errors.
My theory is that we'll discover that it is one that your drive
legitimately is rejecting (unsupported LBA48 or something..).

But we won't know until we see the output.

Second patch is attached:  apply *in addition* to the first one.

Cheers

No, the output would be there if those messages came from the patched kernel.

Mmm... that's what I'm using (plus other patches),
so, yes.. give that a try.  2.6.16 does seem to
be shaping up to be a nice kernel.

I will give 2.6.16-rcX a try shortly, here is the error again (with a 
freshly patched 2.6.15.4) just to rule out any problems with the first 
time that I patched:

OK, failed for me too - I updated to 2.6.16-rc4 and it still failed
(despite -F) so I fixed by hand.

Oh good, *now* we've gotten somewhere!!

Albert / Jens / Jeff:

The command failing above is SCSI WRITE_10, which is being
translated into ATA_CMD_WRITE_FUA_EXT by libata.

This command fails -- unrecognized by the drive in question.
But libata reports it (most incorrectly) as a "medium error",
and the drive is taken out of service from its RAID.

Bad, bad, and worse.

Libata should really recover from this, by recognizing that
the command was rejected, and replacing it with a simple
WRITE_EXT instead.  Possibly followed by FLUSH_CACHE.

So.. I've forgotten who put FUA into libata, but hopefully
it's one of the folks on the CC: list, and that nice person
can now generate a patch to fix this bug somehow.

Cheers

Thanks Mark

I'm glad it's a bug and not bad hardware.

I am quite concerned that the basic effect of just booting a practically
vanilla 2.6.16-rc4 like this was to fry my raid array.

Luckily it dropped 2 (of  3) disks so quickly that the event counter was
the same allowing an easy rebuild.

2.6.15 has similar issues but they seem to happen *very* infrequently by
comparison - this hit me several times during a single boot.

Should Linus (cc'ed) hold off on 2.6.16 because of this or not?

I have what looks like similar problems. The issue I have is that I 
don't think the problem is ONLY libata related.
I have two linux PCs. One called "games", the other called "localhost".
The problem happens quite quickly on the old "games" machine, but I can 
run for days/weeks until I see the problem on the "localhost".
It might be happening on the "localhost", but I am just not noticing. 
The difference being that if reiserfs sees this error, it cannot 
recover, and I have reiserfs on the "games" machine. The "localhost" 
only uses ext3, and ext3 recovers gracefully from this problem.
Can I use libata on this old "games" machine? It is an old Pentium 3 
machine.
In any case, The "games" machine is currently switched off until I can 
find a kernel that works, so I will happily test different kernels and 
patches, if people have suggestions.

I have two desktop linux machines. One is an old Pentium 3 which shows 
the following errors(no libata involved):

This looks like a simple bad disk drive. Notice that the sectors are
quite close.
If you like you can move the drive to a working machine and run a
badblocks on it.
do 'man badblocks' before you start.
Is it SMART capable? What does
  smartctl -a /dev/hdc
show?

ddrescue may be your friend if you need to recover data.

Reply offlist if this is the case.

Have you got smartd running?
I get a similar problem running some smartcl commands (-s on and -o on)
I suspect this is a libata ata passthru problem - but I'm *guessing* :)

check the last messages in dmesg then run
smartctl -data -s on /dev/sd...
smartctl -data -o on /dev/sd...
See if there are new messages in dmesg

The disk really does have bad sectors in this case (above).

PIO errors?  Are you using Alan Cox's experimental PATA code for libata?

Well, no doubt whatsoever about it being a "regression",
since the FUA code is *new* in 2.6.16 (not present in 2.6.15).

The FUA code should either get fixed, or removed from 2.6.16.

The disk has NO bad sectors. It has been checked using two different tests.
1) seatools (The seagate test tool passed the deep test where it reads 
all sectors.)
2) dd of the entire HD image onto another HD.
No sector errors were encountered in either case.

No, this is Linux kernel 2.6.15.1 with no patches.

The *only* test that matters is to enable S.M.A.R.T.,
and read out the error logs from it.

"smartctl" is the tool.

I have seen a set of drives that has reported UncorrectableErrors
and :
    * Shows the Uncorrectable error in the SMART log
    * Passes a full SMART test
    * Shows no remapped sectors
    * Passes the vendors drive test
    * Now fully passes a dd if=/dev/hdx of=/dev/null with no errors.

They were a set of 250GB SATA drives by the same vendor; I've taken
 them out one at a time as each did the same thing and replaced them
with another vendors drive.  They were all in use in RAID-1 MD 
configuration (under heavy load).

I do wonder about the 'uncorrectable error rate' that vendors report;
it doesn't seem very large - but I'll admit to not understanding its
units.  Are soft non-repeatable uncorrectable errors expected in
principal? (Pointers to a good explanation of what this actually
means would be appreciated).

I do wonder how often this happens to people and if the read succeeds
again they just blame it on software.

SMART is unreliable for many cases

The very early SATA code didnt decode the errors from the drive fully so
could produce bogus reports. The current code decodes it and also
displays the ATA level diagnostics so should be reliable.

It still is unreliable, as being discussed in another thread.

libata wrongly says "medium error" any time it issues a command
that the drive rejects (unsupported, invalid parameters, etc..).

This is biting a few people in 2.6.16-rc*, due to the FUA stuff.

It seems to still get a single case wrong. But it does the report the
ATA state correctly still.

It is driven by a table in 

libata-scsi.c:ata_to_sense_error()

so if you can figure out the wrong entry and tweak the table that would
be great

It's the fall-through case, where the table is not used.


         /* No error?  Undecoded? */
         printk(KERN_WARNING "ata%u: no sense translation for op=0x%02x status: 0x%02x\n",
                id, opcode, drv_stat);

          * has failed.
          */
         *sk = MEDIUM_ERROR;
         *asc = 0x11; /* "unrecovered read error" */
         *ascq = 0x04; /*  "auto-reallocation failed" */

Actually, now that I've done a little more digging, this FUA stuff
is inherently dangerous as implemented.  A least a few SATA controllers
including pipelines and whatnot that rely upon recognizing the (S)ATA
opcodes being using.  And I sincerely doubt that any of those will
recognize the very newish (and aptly named..) FUA opcodes.

These may be unsafe in general, unless we tag controllers as
FUA-capable and NON-FUA-capable, in addition to tagging the drives.

It certainly is dangerous. I guess we should turn off FUA for the time 
being. Barrier auto-fallback was once implemented but it didn't seem 
like a good idea as it was too complex and hides low level bug from 
higher level. The concensus seems to be developing blacklist of drives 
which lie about FUA support (currently only one drive). Official kernel 
doesn't seem to be the correct place to grow the blacklist, Maybe we 
should do it from -mm?

All sii controllers and piix/ahci seem to handle FUA pretty ok. And 
yeah, we may have to create controller blacklist too.

BTW, can you let me know what drive we're talking about now (model name 
and firmware revision)?

For 2.6.16, the only sane solution for now is to just turn it off.

Somebody want to send me a patch that does that, along with an ack from

I really hate having a _global_ variable called "fua". That's just bad 
taste. I would suggest calling it "atapi_forced_unit_attention_enabled", 
but maybe that is going a bit overboard. It's definitely better than just 
"fua", though.

<shrug>  It will go away when things are fixed, and only users who are 
testing will even bother with it.

Looking over the module subsystem, it looks like one could use 
module_param_named() to achieve proper namespace separation (C versus 
module opt) -- then you could call it libata_fua -- but for a temporary 
module option it seems like more trouble than its worth.

It's actually short for "Force Unit Access",

Or maybe a whitelist instead, since nearly all existing hardware
pre-dates FUA commands.

Or maybe just have a libata function to test whether the FUA commands
actually work or not, before enabling them for general use.
*That* could be a much better approach, given the large number of
possible drive/controller combos, and it cuts down on the maintenance
headache of having to list everything on a list somewhere.

David:  we need to see the output from "hdparm --Istdout /dev/sda
(or whichever drive it was that was failing on your system).

That's the best solution right now. I guess there's no way around a
blacklist for FUA support and we need time to grow that :-(
And proper fallback to non-FUA writes with disabling FUA based barriers
as well.

Mark, what drive model+firmware are you using?

For controllers just add it as a host flag and it can be handled the
same way as LBA48 is right now. It may also be some hosts can issue FUA
with a bit of bandaging (state machine resets/pio etc)

Are there any other tests; like swapping the disks to the other

So, yes, the drive is either lying about "* WRITE_{DMA|MULTIPLE}_FUA_EXT",
or it didn't like the parameters it was given, or the SATA/IDE controller
chip didn't like the command.

The error handling still sucks, regardless of FUA.
All of this nonsense about "Medium Error" is pure bogosity here.

I've flipped my tree to report Aborted Command. Not sure there is a
better scsi sense match for "it broke and I dont know why"

I wonder if the non-FUA component here is the sata_sil,
rather than the two Maxtor drives.

Also, your drives have different firmware,
but both have trouble with FUA here.

(sdb is slightly newer, and larger, than sda).

sata_sil is indeed a piece of hardware that needs to know the opcodes 
ahead of time...

those drives should support all FUA opcodes properly, both queued and unqueued

His first drive (sda) does not support queued commands at all,
but the newer firmware in his second drive (sdb) does support NCQ.

Both drives support FUA.

To trust or not to trust?

I have a 400GB SATA drive: WDC WD4000KD-00N.  With these errors in dmesg 
that have been mentioned throughout the thread, should I trust Linux using 
this drive, or should I remove it/wait until a patch is released to 
address this issue?

Also, in the forums (storagereview.com I believe), it has been noted that 
these drives do NOT work on the Intel ICH5 controller, and this turned out 
to be true, when I put it on the Intel ICH5, the box stalls for 2-3 
minutes and then it does not see the drive.  However, on the Silicon 
Image, Inc. SiI 3112 chipset or Promise SATA/150 TX2 it works okay but it 
has those errors in dmesg.

My question is, performing long and short smart tests, everything is 
physically ok with the drive; however, I probably should not use this 
drive for anything important in Linux, comments?

Justin.

Could someone *PLEASE* produce a *unified* patch that is compatible with 
2.6.16-rc5 or 2.6.15.4 so I can reproduce the error?

Mark had two patches, I have had the most PIA time getting them to work, 
patch properly, etc..

With 2.6.16-rc5:

As a user I prefer
  It Broke And I Dont Know Why
to
  Aborted Command

(honesty is the best policy)

I certainly hate Medium Error as modern hard disks seem to be flakier
than ever.

I actually have 3 of those drives - one runs through sata_via and
doesn't have the same problem.

(the sata_via ones *do* have :
 ata3: status=0x50 { DriveReady SeekComplete }
 ata3: PIO error
problems with SMART)

And once again, not enough information in the error messages
for anyone to actually do anything about it (not David's fault).

What command do you use to get that bug to pop up?

BTW:
hdparm-6.5 is now available (sourceforge),
and should show all of the fancy features
of your drives for comparism between versions.

"DriveStatusError" is "Command Aborted" in ac-speak.
 From the man page for smartctl, we read:

There's a chance that your drives simply do not fully support this feature,
and are rejecting attempts to use it.

By the way, the latest 2.6.16-rc5-git4 is available,
and has FUA turned off by default now.  So it should
work with your drives, and *you* are expected to verify
that for us all now.

Mark,

After patching to 2.6.16-rc5-git4, we should no longer see these errors 
right?  Then I can use my drive again without worrying about data loss? :)

Yeah, I know - I've got it on the machine... but it's my wife's machine.
I've asked nicely but she's editing a Hercule Poirot video so I'm not
allowed to reboot it for a while...

I've told her I'm not making pancakes until I've tested it so expect a
report Real Soon Now...

By the way, the latest 2.6.16-rc5-git4 is available,

I am using 2.6.16-rc5-git4, and after running:

# smartctl -data -o off /dev/sdc

I get:

Did you mean you wanted us to test it like we normally do, ie, copy 
files/md5sum them on the disk and see if we can make it occur again, or?

That's probably just your drive reporting "unsupported sub-command".
Nothing serious -- the man page for smartctl even mentions the possibility.

Yes.  The S.M.A.R.T. stuff doesn't matter nearly as much as normal I/O.

And Justin, can you get those S.M.A.R.T. errors to pop up on 2.6.15 as well?

Have not tested, can test later if necessary, running some I/O tests to 
the disk which is probably going to take quite a while to see if I can get 
it to error again with 2.6.16-rc5-git4.

If there are FUA problems, it would be immediately apparent on the first 
write...

OK that worked (the pancakes - the kernel's not doing so well...)

The boot is pretty clean.
I ran an xfs_repair -n on the lvm volume and got the following errors.
The repair reported a clean filesystem and the drive was not booted from
the raid so that's a big improvement.

I was not able to trigger similar messages on ata1 but a simple dd
doesn't trigger the messages on ata2 either (and for various reasons,
xfs_repair wouldn't run on ata1 - I thought I'd leave it and report this
first)

Wouldn't that just be 0/0/0?  IIRC the standard defines that as "NO 
ADDITIONAL SENSE DATA" which sounds to me like another way of saying "I 
don't know what went wrong, but that didn't work".

As of 2.6.16-rc5-git4, I have written 281GB so far over a period of 48+ 
hours with no errors yet :)

Will keep you updated if I see any errors, but so far, so good!

Just FYI - I'm away (in Canada) for 2 weeks so can't do any additional
testing until I return.

Am I correct, in that your last test on rc5-git4 was a failure?

But without the "opcode" display in the error messages,
so we have no idea exactly what caused the errors (again!)?

[Whatcha doin up here?]

Using 2.6.16-rc5-git4 and removing a directory of around 5.0GB of files 
while streaming a 1MB/s video stream on another (SATA disk), the I/O 
seemed to freeze up for a moment and I got this error:

[4342671.839000] ata1: command 0x35 timeout, stat 0x50 host_stat 0x22

Only 1 in dmesg, any idea what causes this error?

The drive it occured on was a 74GB raptor on an ICH5 controller.

SCSI opcode 0x35 is SYNCHRONIZE_CACHE.

Pity we don't know exactly what that got translated to by libata.
It would have been either a FLUSH_CACHE of some kind,
or possibly(?) one of the _FUA_ commands.

Oh, wait a sec.. on that path, libata actually does show the ATA opcode,
which would have been WRITE_DMA_EXT.  Not an FUA command.

Dunno what it's complaining about, though.

It was *much* better than rc4 but it did have an error.
I *think* the problem I'm seeing is likely to be similar to the one I 
orginally reported (on 2.6.15 IIRC)
Same sporadic warning/error which didn't usually trigger the

Yes. I thought the/a opcode-verbose patch was in  there but I  guess not.
I don't have remote console access to the machine so wouldn't be able to 
carry out reliable kernel tests - sorry.
Of course I'll do this as soon as I return.

hdparm-6.5 is the current version now.  Both it, and 6.4,
build/install/run cleanly on Ubunutu-5.10, Debian-Sarge,
and SLES9-SP3.

You seem to be having trouble on only Redhat distros..
I guess they've done something unfriendly again.

Care to be more specific about what Redhat is doing?

looks like our userspace includes aren't up to date with some of the kernel
changes, so currently they're lacking the ide_task_request_t and related
taskfile bits.

Ahh.. Thanks, Dave.

hdparm-6.6 being released *now*, with that stuff #ifdef'd out when
the necessary header structs are missing.

It builds/runs for me, on RHEL4 at least.

I'll mail you the first few hundred errors from the compiler after I go 
find 6.5 and try that. My ubuntu tester reported similar results, so I'm 
not sure what we are doing.

The 0/0/0 sense is already used. The question is what error do you use
with that sense. At the moment I'm using aborted command.

Hi

Back now :)

I've upgraded to 2.6.16 and applied your verbosity patches.

I've persuaded my array to re-assemble and during the resync I got these
messages

dmesg:
ata1: translated op=0x28 cmd=0x25 ATA stat/err 0x51/04 to SCSI
SK/ASC/ASCQ 0xb/00/00
ata1: status=0x51 { DriveReady SeekComplete Error }
ata1: error=0x04 { DriveStatusError }
...(18mins later)
ata1: no sense translation for op=0x28 cmd=0x25 status: 0x51

SK/ASC/ASCQ 0x3/11/04
ata1: status=0x51 { DriveReady SeekComplete Error }

smartd is not running
This did not cause the raid subsystem to boot the disk (thank goodness!)

Just providing a little more followon information...

I have had a further 52 of these messages over the last day. No obvious
cause.
Mar 22 13:14:55 haze kernel: ata2: no sense translation for op=0x28
cmd=0x25 status: 0x51
Mar 22 13:14:55 haze kernel: ata2: status=0x51 { DriveReady SeekComplete
Error }

Most recently this happened:

Mar 22 13:47:09 haze kernel: ata2: no sense translation for op=0x28
cmd=0x25 status: 0x51
Mar 22 13:47:09 haze kernel: ata2: status=0x51 { DriveReady SeekComplete

Mar 22 13:47:09 haze kernel: end_request: I/O error, dev sdb, sector

with dmesg piping up with:
raid1: sdb2: rescheduling sector 5801424
raid1: sdd2: redirecting sector 5801424 to another mirror

no drives were kicked from the array.

LibPATA code issues / 2.6.16 (previously, 2.6.15.x)

[Justin Piszcz]

Yet a new problem, under 2.6.16, when I fill up the disk, smartmontools 
reports this:

Apr 21 14:24:20 p34 smartd[1443]: Device: /dev/sdc, 1 Currently unreadable

Apr 21 14:54:20 p34 smartd[1443]: Device: /dev/sdc, 1 Offline uncorrectable
sectors

What made it error under 2.6.16?

$ time dd if=/dev/zero of=file.out
dd: writing to `file.out': No space left on device

Under 2.6.15.x, I did not see this behavior, is this going bad, or?

That's a disk-level problem.  You've got bad sectors.

You can force the disk to replace the bad sectors by doing a disk-level 
write:

	dd if=/dev/zero of=/dev/sda1 bs=4k

and then test the disk with

	smartctl -d ata -t long /dev/sda

If sectors continue to die, the disk is toast.

NOTE! Obviously don't do this before you've backed up the disk.  Depending 
on the filesystem, you might just have overwritten something important, or 
just your pr0n collection ;)

Jeff, please be a little more careful about telling people commands like 
that. Some people might cut-and-paste the command without realizing what 
it's doing as a way to "fix" their problem.

Yes, but to a _file_ on the partition (ie he didn't overwrite any existign 
data, just the empty parts of a filesystem).

I realize that it's not enough for the "re-allocate on write" behaviour, 
and for that you really _do_ need to re-write the whole disk to get all 
the broken blocks reallocated, but my argument was just that we should 
make sure to _tell_ people when they are overwriting all their old data ;)

I did not realize this before, and asked badblocks maintainer Theodore
if badblocks /some/file was supported (the man page says no); but of
course any filesystem can decide to re-allocate blocks for a file.

However, for large files where parts may be bad sectors, I am still
searching for a way to read, then re-write every physical sector
occupied by the file. 

With the purpose to remap the bad sectors inside large MPEG files (where
I would rather have a few zeroed holes than a read error in them).

Anyone know such tooling exists? I suspect it has to use filesystem
specific IOCTL's to query for the blocks involved.

Regards,

Leon

This much easier to solve in the player software:
do {
	ret = read(fd, buffer, size)
	if (ret > 0) {
		playbuffer(buffer, ret)
	} else if (ret < 0) {
		switch(errno) {
		case EIO:
			playbuffer(allzeroesbuffer, size);
			/* skip over this frame because of disk problems */
			lseek(fd, size, SEEK_CUR);
			/* TODO: Handle return or lseek() here */
		}
	}
} while(ret != 0)

The (somewhat) portable ioctl() FIBMAP would suffice. 
That way you find out what blocks are this file is mapped to,
and could add some of these blocks to the badblock list of e2fsck.

different drive, different cable, same controller, but second port

So that Stat/err = UDMA_CRC_Error_Count!

No, I don't think it is -- there's a bit in the drive status
for indicating CRC errors, and it is not showing up here.

I think it's still just libata sending some command that this
drive does not implement.  You really need to dump out the failed
ATA opcode.

I *think* this (uncompiled, untested) patch may do it for you on 2.6.16/17:

had to change

KERN_WARN -> KERN_WARNING

then more errors

the patch never worked for me even when I had gotten it to work in
2.6.15.4, it never showed me what I wanted to see

drivers/scsi/libata-scsi.c: In function 'ata_gen_fixed_sense':
drivers/scsi/libata-scsi.c:638: error: 'ata_op' undeclared (first use in
this function)
drivers/scsi/libata-scsi.c:638: error: (Each undeclared identifier is
reported only once
drivers/scsi/libata-scsi.c:638: error: for each function it appears in.)
make[2]: *** [drivers/scsi/libata-scsi.o] Error 1

do you know who wrote the original patch?

Eh?  After fixing the KERN_WARN -> KERN_WARNING part,
the patch compiles / links cleanly here on 2.6.17.
(fixed copy below).   Still untested, though.

I did.

Mark,

I've set a disk faulty in my SW RAID5 and rebuilding it now, note, in the 
past two rebuilds I have done (in exact same manner & disk) I've gotten 
3-4 of these or so, so if I do not get them this time, that will be 
extremely odd.

Justin.

Mark!! It did it again, here you go:

Does this help?

Can we eliminate the cause of these errors now?

Jeff or Alan,

Does that ATA translation help in determining what *bad* commands are 
being sent to the drive?

This occurs on two separate identical disks.

Jeff, the patch is applied and box booted the new kernel and I reproduced 
the error messages, THAT is what is produced with the patch.

Perhaps the patch is not printing out the correct error message?

This shows that the source file was patched in libata-scsi.c.

         /*
          * Use ata_to_sense_error() to map status register bits
          * onto sense key, asc & ascq.
          */
         if (tf->command & (ATA_BUSY | ATA_DF | ATA_ERR | ATA_DRQ)) {
                 printk(KERN_WARNING "ata_gen_ata_desc_sense: failed 
ata_op=0x%02x\n", ata_op);
                 ata_to_sense_error(qc->ap->id, tf->command, tf->feature,
                                    &sb[1], &sb[2], &sb[3]);
                 sb[1] &= 0x0f;
         }


This shows the kernel version.
$ cat /usr/src/linux/.version
4

This shows I am running the patched version.
$ uname -a
Linux p34.internal.lan 2.6.17.3 #4 SMP PREEMPT Fri Jul 7 09:47:53 EDT 2006

Maybe something is blocking the opcode output from showing correctly?

Mark,

Check line 519, this is where it is printing the error (I believe) and 
the patch does not print the ata_op here.

It is in the ata_to_sense_error() function.

I've already patched, as you can see, recompiled, etc..

This part needs the ata_op:

     519  translate_done:
     520         printk(KERN_ERR "ata%u: translated ATA stat/err 0x%02x/%02x to "
     521                "SCSI SK/ASC/ASCQ 0x%x/%02x/%02x\n", id, drv_stat, drv_err,
     522                *sk, *asc, *ascq);

Re: LibPATA code issues / 2.6.15.4 (found the opcode=0x35)!

[Justin Piszcz]

I made my own patch (following Mark's example) but also added that printk 
in that function.

Jul  9 16:37:52 p34 kernel: [4294810.556000] ata4: error=0x04 { 
DriveStatusError }

Now that we have found the ata_op code of 0x35, what does this mean?  Is 
it generated from a bad FUA/unsupported command from the kernel/SATA 
driver?

Justin.

In /usr/src/linux/include/linux/ata.h:

   ATA_CMD_WRITE_EXT = 0x35,

Perhaps these drives do not support this command or do not support it 
properly?

Any idea, Jeff/Alan?

Jeff/Mark, from these errors can we reach a consensus as to the cause of 
these errors and how to eliminate the problem?

Any follow up now that we have the failed ata-translated op codes?

Thats "write" so if that is reporting as an unknown command something
very odd indeed is happening.

LibPATA code issues / 2.6.17.3 (What is the next step?)

[Justin Piszcz]

Alan/Jeff/Mark,

Is there anything else I can do to further troubleshoot this problem now 
that we have the failed opcode(s)?  Again, there is never any corruption 
on these drives, so it is more of an annoyance than anything else.

Other people also have this problem with these drives if you search Google 
but I am not sure they are aware of where to report their errors/problems.

opcode=0x35 & opcode=0xca

Justin.

Nothing strikes me so far other than the data not making sense. Possibly
it will become clearer later if/when we see other examples.

For me it's SMART related.

smartctl -data -o on /dev/sda reliably gets a similar message.
Justin - does this smartctl command trigger a message for you?

I've been mailing on and off since January-ish.
(http://marc.theaimsgroup.com/?l=linux-ide&w=2&r=7&s=libpata&q=b)

Back in March I was running 2.6.16 (with a different version of Mark's
opcode patch) and I sent an email with the following info:

dmesg:
ata1: translated op=0x28 cmd=0x25 ATA stat/err 0x51/04 to SCSI
SK/ASC/ASCQ 0xb/00/00
ata1: status=0x51 { DriveReady SeekComplete Error }
ata1: error=0x04 { DriveStatusError }

Does that help with the diagnosis?

Also see my emails: SMART on SATA reporting errors?
  http://marc.theaimsgroup.com/?l=linux-ide&m=113933732903205&w=2

I did reply but got no response so I assumed I was just so far off base
that I was being ignored  :)

Unfortunately not, the correct patch you need is attached to get the 
ata_op code, against 2.6.17.3.

In that case SMART just isn't enabled. smartctl -d ata --smart=on
/dev/sda should make those messages go away.

Some BIOSes have a setting to enable/disable SMART, though the option
is usually badly documented (hey, what do you expect from BIOS
writers).

[mutter, mutter, getting a teeny bit fed up with applying the same

feedback (apart from Erik - ta - who was off base, it doesn't appear to

It is up to the current subsystem maintainer to help investigate this
and come up with a solution, in cooperation with eager testers such
as yourself.  I gave away my kernel subsystem maintainer's duties about
seven years ago, because it just takes too much time to do it really well.

In this case, I'm proving a tiny amount of help, simply because I don't
see anyone else even trying, and there is obviously something wrong here.

Now.. your hacked version of my simple patch is incorrect.  It is frequently
dumping out ata_op=0x51, which is obviously the ATA status value not the
original ATA command byte.

But ignoring that, we also see some valid output from where it does trip
the code from my original patches:  ata_op=0x35.

So, the drive is rejecting an LBA48 WRITE operation, which should happen
only if the drive does not have LBA48 support.  Now, I know you posted all
of this nice info months ago, but let's see it again now, for the exact
drive that is generating that specific message.  We need to see the output
from "hdparm --Istdout /dev/sdX" for that drive.

Thanks

Those are non-DMA WRITE opcodes.  Using PIO for I/O is pretty rare these days,
so I'm betting that this is not a hard disk device -- compactflash?

They are Western Digital 400* drives.

[4294678.049000]   Vendor: ATA       Model: WDC WD4000KD-00N  Rev: 01.0
[4294678.050000]   Vendor: ATA       Model: WDC WD4000KD-00N  Rev: 01.0

On a SiL controller, it also happens when they are on a promise controller 
too.

Which *exact* unit generated the WRITE errors you posted about?

Okay.  So why are we issuing PIO WRITE commands to drives that
obviously should only be sent DMA commands by libata?

Perhaps that's the bug.

Both have generated the errors, they are identical drives and firmware.

Oh wait.. I remember this.. No, those are DMA commands,
despite the misleading libata name for them.  We went through
this before last spring..

Okay.  So I wonder what's really going on.
The next step would be to instrument the interrupt handler,
so that when it sees bad-status, it dumps out the stat/err values
right then and there, before anything else can muck with them.

It might also be good to have it dump out the controller engine's
DMA status/err values, assuming the controller has registers for those.

Then we should get a better picture of what's going on.
Assuming the drives aren't lying to us (a perfectly good assumption here),
then the controller must be aborting the transfer unexpectedly.

That being said, I see from

https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=177951

that a blacklisting of some Maxtor drives for this issue has
supposedly occurred or been pushed and accepted "upstream" in git ....
 For the obvious (selfish) reasons, I'd like to minimize the number of
Maxtor drives that are blacklisted, as I don't believe this is a drive
issue at all.

If there's a drive model out there reporting support for FUA but
screwing it up, I'm all ears as that's something I need to know about.
 If basic adapter functional testing is required for some of these
low-level commands, then that might be something I can help with too
(on a very limited scale), since we have access to ~100 different
chipsets.

I didn't know offhand so we plugged in a bus analzyer and took a look
here in the lab... We didn't have a 3114 lying around, but issuing the
Write DMA FUA (0x3D) opcode on a 3112 resulted in a D0h soft hang.  I
think they're related (4-port vs 2-port).

Looking at the bus trace, the command is issued on the SATA bus, the
drive generates a DMA Activate FIS which is accepted by the 3112, and
then the 3112 generates a Data Payload FIS (46h) with no contents.

The first DWORD of the payload is a HOLD primitive, to which the
device promptly responds with HOLDA, and the two are in a soft bus
lock and will sit forever.  No data is ever generated by the host
(stopped capture after 4 seconds).

I believe this core should not be part of the FUA whitelist.  If I
remember correctly, there are other implementations out there with
similar limitations to opcodes this "new" to ATA.

sata_nv was written by NVIDIA.

I'm a someone with such a controller (that's my boog here)
But I only have these drives.
So I can only confirm the combo it deadly.
(I could possibly try to plug one on the nforce4 controller, not sure if
extracting the box from the tangle of cables and hardware he's part of
is worth it. sata_nv is rev-eng, while the siI docs are public, right?)

I do suspect Eric D. Mudama knows if the problem is on the hard-drive
side though

Mmm.. somebody with one of those controllers should check
to see if *any* drives work with FUA, and blacklist the controller
instead of the drives if everything is failing.
