Hello again,
now on the same system (hardware configuration unchanged, except that
I attached a DVD burner yesterday), I got dozens of errors like these:
----------
Mar 22 13:47:33 bakunin kernel: __find_get_block_slow() failed.
block=197478301302784, b_blocknr=0
Mar 22 13:47:33 bakunin kernel: b_state=0x00188021, b_size=4096
Mar 22 13:47:33 bakunin kernel: device blocksize: 4096
Mar 22 13:47:33 bakunin kernel: __find_get_block_slow() failed.

Mar 22 13:47:33 bakunin kernel: b_state=0x00188021, b_size=4096
Mar 22 13:47:33 bakunin kernel: device blocksize: 4096
Mar 22 13:47:33 bakunin kernel: grow_buffers: requested out-of-range
block 197478301302784 for device dm-14
Mar 22 13:47:33 bakunin kernel: EXT4-fs error (device dm-14):
ext4_xattr_delete_inode: inode 1022: block 197478301302784 read error
----------
Please not that I had run an fsck on the mentioned device only a
couple hours earlier, with no errors found.
Now, does this indicate a hardware problem?
My drives' SMART info reports not a single reallocated sector. But one
drive has a high Hardware_ECC_Recovered count, but I got it that's
nothing to actually worry about. Well, it might indicate bad cabling,
though.

This was casued by the call to ext4_error(); the "scheduling while
atomic" BUG error was fixed in 2.6.29-rc1:

ext4: fix BUG when calling ext4_error with locked block group
The mballoc code likes to call ext4_error while it is holding locked
block groups. This can causes a scheduling in atomic context BUG. We
can't just unlock the block group and relock it after/if ext4_error
returns since that might result in race conditions in the case where
the filesystem is set to continue after finding errors.

It's going to be moderately painful to backport this to 2.6.28 and
2.6.27, but we can look into it.

This was caused by an on-disk filesystme corruption which mballoc
detected, which flagged an EXT4 error, which then triggered the BUG.

Sounds like an inode table got corrupted.

Yeah, we have a patch queued up so we can identified the bad inode
number that caused that, but it points to more inode table corruption.

That's another indication of data corruption in inode 1022. This
could be hardware induced corruption; or it could be a software
induced error. There's been one other user with a RAID that had
reported a strange corruption near the beginning of the filesystem, in
the inode table. How big is your filesystem, exactly? It could be
something that only shows up with sufficiently large filesystems, or
it could be a hardware problem.
Can you send me the output of dumpe2fs of the filesystem in question?
And something that would be worth doing is to use debugfs like this:
debugfs /dev/XXXX
debugfs: imap <1022>
you'll see something like this:
Inode 1022 is part of block group 0
located at block 128, offset 0x0d00
Take the block number, and then use it as follows:
dd if=/dev/XXXX of=itable.img bs=4k count=1 skip=128
Where the parameter to "skip=NNN" should be replaced with the block
number reported by debugfs's imap command.
Thanks,

Attached, as well as the itable image.
By the way, yesterday's fsck on another file system (/home) placed
almost 8,500 (!) files and directories in lost+found. I have not a
single error message regarding this device in my log files. All
files/directories were originally placed in the same parent directory.

OK, so about 5 gigs; not all that big at all. I was starting to worry
that maybe we had some 32-bit signed/unsigned problem, but that would
be showing up in the 8+ TB range.

I've analyzed the itable image, and it looks valid; in particular, I
didn't see any evidence of corruption in inode 1022.

There is something very wrong going on here, and I'm at a loss why no
one else is reporting anything like what you are seeing.
Are you able to run a stock, unmodified mainline kernel on your
system? At this point I'd really like to see if the problems you are
seeing can be replicated with a stock 2.6.29-rc8 kernel.

Hi Ted, I just compiled and installed 2.6.29-rc8 vanilla. Before
running it, I booted from a live CD and fsck'd all my file systems to
get them into a consistent, clean state.
Now, after booting 2.6.29-rc8 and writing stuff to dm-14 (/usr), I again get:
----------

----------
(the same for other inodes as well)
I've again attached the output of dumpe2fs (maybe something has
changed in the meantime..?) and an image of inode 4501.

Hmm, so the block number is: 7B0800000000 that indicats that
i_file_acl is 0, but the bits in i_file_acl_high are set. E2fsck
doesn't currently detect and fix this case --- which is a bug in
e2fsck that I'll fix --- but it begs the question how the
i_file_acl_high could have gotten set in the first place.
Was this a freshly created ext4 filesystem, or one that was converted
from ext3?

Freshly created ext4 fs.

Hello Ted,
I am considering moving my data to ext3, since in a week (or two) I
will have to use the computer on which the bug occured as a (hopefully
stable) production system. Should I keep an Image of the /usr
partition, in case you have any further questions or something?
Thanks for your help so far,
Richard
