Hi,
I think we have some minor corruption happening with a new (about two
weeks old) ext4 file system. Our backup script spat out bunch of errors
last night while trying to read the file ACLs:
getfacl: apps/Gestalt.Net/SetupCD/program\040files/Business\040Objects/Common/3.5/bin/Cdo32sv.dll: Input/output error
getfacl: apps/Gestalt.Net/SetupCD/program\040files/Business\040Objects/Common/3.5/bin/U3520chs.dll: Input/output error
getfacl: apps/Gestalt.Net/SetupCD/program\040files/Business\040Objects/Common/3.5/bin/ReportRenderer.dll: Input/output error
getfacl: apps/Gestalt.Net/SetupCD/program\040files/Business\040Objects/Common/3.5/bin/ParameterDesigner.dll: Input/output error
...
And in syslog I see these warnings from the kernel:
Mar 10 00:06:01 hermes /USR/SBIN/CRON[10875]: (root) CMD ( /usr/local/bin/rsync-backup-all.sh)
Mar 10 00:06:24 hermes kernel: init_special_inode: bogus i_mode (53253)
Mar 10 00:06:24 hermes kernel: attempt to access beyond end of device
Mar 10 00:06:24 hermes kernel: dm-0: rw=0, want=1312475392770056, limit=2147483648
Mar 10 00:06:25 hermes kernel: attempt to access beyond end of device
Mar 10 00:06:25 hermes kernel: dm-0: rw=0, want=1312475392770056, limit=2147483648
The filesystem is still in use (and working okay, AFAICT), but I'll need
to fsck this tonight. Is there any useful data I can gather from the fs
before (or while) I do that which might help track down the cause?
This system has been running 2.6.29-rc6 (x86_64) since this filesystem
was created. I did a quick scan of the ext4 commits since then, but none
of them obviously address this unless maybe it's related to 7ce9d5d -
"ext4: fix ext4_free_inode() vs. ext4_claim_inode() race"
Regards,
Kevin.

Can you try debugfs /dev/whatever, and then do:
debugfs> stat
apps/Gestalt.Net/SetupCD/program\040files/Business\040Objects/Common/3.5/bin/Cdo32sv.dll
(all one line there, and this is assuming that apps/ is the root dir on
that filesystem, if not adjust accordingly...)

If anyone has a chance, fixing this error message to be not-useless would
be good... Including the device name and the inode number would help
track down the source of the problem.

All garbage. Running e2fsck should fix this, though it won't explain
why it got corrupted in the first place..

Okay, I grabbed the e2image file first.
Huge, but full of holes of course.

This looks like a block written to the wrong place on disk. One of
the things that can be done is to dump out the disk block
corresponding to inode #867 before the fsck, and see if we can
recognize what the source of the block was. I don't see any ASCII in
any of the files (i.e., 0xdca60244, 0x5c9e956c, etc. don't appear to
be ascii), but it might be that we could determine what the block that
got written into the inode table originally came from.
As Andreas said, this e2fsck will this, but it won't explain how a
block in the inode table got corrupted in the first place. It could
be a random hardware hiccup; it could be a corruption on disk or in
memory that lead the Linux kernel to write the block in the wrong
place, etc. The problem is that it could be a filesystem or kernel
bug, but it could also just as easily be a hardware one-time failure.
Failures like this have been reported on ext3 filesystems as well, but
it's rare, and it's been written off to hardware failure, although it
could be really anything --- from the device driver, block layer, a
filesystem problem, or hardware hiccup.
Given that you've fixed it, all I think we can tell you is to keep an
eye out for any further failures....

These all mean the inode is garbage. The Lustre e2fsprogs has a patch
"e2fsprogs-badness_counter" that tracks the number of errors hit in
the inode, and clears it if it appears to be garbage (as in your case),
instead of turning a pile of manure into neatly organized fertilizer.

Hmm, is this read beyond EOF? The block pointers should be fixed by this
time, so there may be a hole in e2fsck at this point. I assume you do
not have a 10TB filesystem here.

Thanks Ted. Just so I know what I'm doing if/when this comes up again, I
guess the process would be:
- debugfs /dev/some-filesystem
- debugfs: stat "some/problem/file"
- get the inode number from the output above (867 in this case)
- debugfs dump 867 inode867.bin
Or perhaps running e2fsck -n first to see which inodes really look
corrupted and get the numbers that way.

Actually, it's a bit more complicated than that. I should really add
a hook to debugfs to automate this, but... to find the block to grab,
you do this.
1) Grab the following fields from dumpe2fs (or debugfs's "stats" command)
Inodes per group: 8192
Block size: 4096
Inodes per group: 8192
Inode size: 256
2) To find out which block group the inode is located in, we calculate:
inode bg = inode_number / inodes_per_group
= 867 / 8192 = block group 0
(everything done using integer division, rounding any fraction down to 0.)
3) To find where the inode table for block group in question can be
found, check out dumpe2fs.
Group 0: (Blocks 0-32767) [ITABLE_ZEROED]
...
Inode table at 65-576 (+65)
^^^^^^
OK, we know it begins at block 65.
Now some more math:
inode_per_block = block_size / inode_size
= 4096 / 256 = 16
offset_block = (inode_number % inodes_per_group) / inodes_per_block
= (867 % 8192) / 16
= 54
So now we know that the block containing inode 867 is 65+54 = 119
Now to dump that block, we do:
dd if=/dev/fs-device of=block-119.dump bs=4k skip=119 count=1
> Or perhaps running e2fsck -n first to see which inodes really look
> corrupted and get the numbers that way.
Yep. In general, when you get corruption like this, the bad inodes
comes in chunks of 16 (if you are using 256 byte inodes) or 32 (if you
are using 128 byte inodes).

Or you can use imap (which Ted probably wrote in the first place. :-)
debugfs: imap some/problem/file
Inode 867 is part of block group 0
located at block 119, offset 0x0180

OK, now I'm embarassed. I had completely forgotten that I had already
implemented it.
And to think I've been doing the hard way most of the time (i.e.,
using dc and doing the calculations manually :-)

Thanks guys.
It looks like there is still a problem there, even after fsck has done
it's cleanup.
Last night I got:

Can you tell us something about the hardware that is behind this
filesystem? What sort of disks, raid controller if any, etc. are you
using?

Sure.
This is a Xeon X3350 quad-core system on an Intel 3210SHLC motherboard,
with 8GB ECC RAM. The filesystem is on top of LVM which is on top of
RAID6 using the md driver. The RAID is comprised of 9 1TB SATA drives, a
mix of Samsung and WDC, using the on-board Intel AHCI SATA controller
and an additional Silicon Image 3132 PCI-e controller and a 5:1 port
multiplier (Sil3726, I think).
Below is the full dmesg after 14 days uptime. Includes bringing the RAID
up from 7/9 to 9/9 and various messing around with the ext4 filesystems.
Cheers,
Kevin.

There isn't anything obvious here that would imply reading a wacky block
beyond the end of the filesystem. I even checked if e.g. you had quotas
enabled and the bogus UID/GID would result in the quota file becoming
astronomically large or something, but the numbers don't seem to match.
There are no blocks in the file, no xattr block ("File ACL" should be
renamed...).

Yes, you should just delete the inodes reported corrupted in your
earlier postings in the 87x range - they contain nothing of value
anymore, and I suspect your troubles would be gone. At least we
wouldn't be left wondering if you are seeing new corruption in
the same range of blocks, or just leftover badness.
Cheers, Andreas

Hi Andreas,
Below is the patch along with other trivial cleanups in fs/inode.c
Fix init_special_inode to print device name and inode number.
Convert simple_strtoul to strict_strtoul.
Remove checkpatch.pl warnings:
Before :-
total: 24 errors, 26 warnings, 1547 lines checked
After :-
total: 0 errors, 0 warnings, 1539 lines checked

More to the point, given that mode bits of the file detected the file
as a named pipe ("Type: FIFO"), it wouldn't have tried to access the
the disk. Trying to read from a named pipe would have resulted in a
hang (assuming no data in the named pipe); writing to named pipe would
have succeeded (and queued the data until another program tried
reading from the named pipe). So getting an I/O error from that file
doesn't make any sense.

The inodes in question that are on that block would be inode numbers
864 to 879, inclusive. You can get the names of the files in question
using the ncheck command:
debugfs: ncheck 864 865 866 867 868 869 870 871 872 873 874 875 876 877 878 879
... but at this point, I'm beginning to wonder if what is going on is
something in the I/O stack is occasionally returning random garbage
when you read from the particular block in question. The contents
reported for debugfs for block 875 should not have caused an I/O error
when you tried reading from the file. You can create your own named
pipe by using the command "mknod /tmp/test-fifo p", and playing with
it. So I'm wondering if when the kernel read block 875, it got one
version of garbage, and then when debugfs read block 875 later, it got
another version of garbage.
One of the original inodes involved was 867, right? You might want to
try using the "stat <867>" command and seeing if it still contains
garbage or not. Since that was e2fsck should have deleted for you (or
did you delete it manually yourself?), it should either be all zero's,
or it should contain the same inode garbage you had sent to the list,
but with an i_links_count of zero if you deleting the file via the
"rm" command. If it contains a different version of garbage, then
something is corrupting that block, possibly on the read path or the
write path.

P.S. The reason why I asked you about your RAID card was because I
recently ended up spending time helping a user who had flashed LSI
firmware onto a Dell PERCS card, because some forum had stated that
the Dell PERCS card was a rebadged LSI hardware. Turns out that while
the card was made by LSI, it was also customized by Dell, and flashing
the non-approved hardware caused a bug to trigger for devices larger
than 4TB, such that a block near the beginning of the filesystem (in
this case, it was a block group descriptor block, so we could easily
recover from the backup descriptor blocks) was getting trashed after
every boot. I had forgotten that you had said earlier that you only
had a 1TB filesystem, but otherwise the symptoms looked very similar,
so I figured I had to ask.
We're now at the stage where I have to start asking questions about
the storage stack --- i.e. have you used this with this exact
hardware/configuration with ext3, and was it stable there,, have you
made any recent changes to the hardware/configuration, etc., since
this is starting to smell like a potential storage stack problem.

But getfattr isn't going to cause a read from the pipe is it? I would
expect that to cause a read from the disk.

I haven't rm'd the files just yet, but good to know which ones they are.

Okay, a quick check shows that getfattr on the test-fifo file doesn't
cause an I/O error and it doesn't block either. A straight read from the
pipe does block of course.

Looks like fsck cleaned up a number of the fields, but not all zeroed.
It seems to have gained some blocks too, but I guess that is meaningless
for an unlinked inode?

The same hardware has been stable with an ext3 filesystem for about 9
months before this. The only other change that I made at the same time
as moving to ext4 was reconfiguring the RAID from what was originally a
10-disk RAID6 array to a 9-disk RAID6 array with room for one hot spare
(though that spare is not installed currently).
In case it matters, the change to ext4 was done by creating a new
filesystem and rsync'ing the data across, rather than upgrading an
existing ext3 filesystem.
Cheers,
Kevin.

Ah, yes, the getfattr would have caused a read from disk. I missed
that the I/O error could have been caused by that.
Still, e2fsck should have cleared the acl block if it was illegal the
last time that you ran a full fsck on the filesystem.

Well, it's likely those files are corrupted, so you might as well
delete them and restore from backup if needed/appropriate/possible.

It's meaningless for an unlinked inode, but it still shouldn't have
happened. I'm not sure how it could have happened in the first place.
Hmmm, I really don't know what to tell you; at this point probably the
best thing to do is to delete the last inodes used in that inode
table block, and then keep a watchful eye on the filesystem.

I guess there was some additional badness that e2fsck hadn't picked up
the on previous runs. And dammit, there's still something wrong.
Attempting to copy the backup files back in, the cp command is hanging
and I got another one of these:
attempt to access beyond end of device
dm-0: rw=0, want=946232834916360, limit=2147483648
Okay, I guess the hang has something to do with the stray file which
turned itself into a named pipe. Trying to remove it again:
hermes:~# rm '/srv/samba/local/apps/Gestalt.Net/SetupCD/program files/Business Objects/Common/3.5/bin/RptControllers.dll'
