           Summary: resizing ext4 will corrupt filesystem
           Product: File System
           Version: 2.5
    Kernel Version: 2.6.37-rc6
          Platform: All
        OS/Version: Linux
              Tree: Mainline
            Status: NEW
          Severity: high
          Priority: P1
         Component: ext4
        AssignedTo: fs_ext4@kernel-bugs.osdl.org
        ReportedBy: kees@outflux.net
        Regression: Yes


Using resize2fs on an ext4 will result in a corrupted filesystem. This is a
regression (obviously).

I would expect "fsck" to be clean on a recently resized filesystem, but it is
not:

Created an attachment (id=41062)
 --> (https://bugzilla.kernel.org/attachment.cgi?id=41062)
script that will demo a corrupted ext4 after resize

This has already been reported to Ubuntu, but was reproduced with an upstream
kernel, so I've opened this report as well.

Yes, this is a regression new to 2.6.37-rc1, which was introduced by
commit a31437b85: ext4: use sb_issue_zeroout in setup_new_group_blocks.

When we replaced the loop zero'ing the inode table blocks with
sb_issue_zeroout, we accidentally also removed this little tidbit:

-               ext4_set_bit(bit, bh->b_data);

... which was responsible for setting the block allocation bitmap to
reserve the block descriptor blocks and inode table blocks.  Oops...

I believe this patch should fix things.

https://bugzilla.kernel.org/show_bug.cgi?id=25352

This regression was caused by commit a31437b85: "ext4: use
sb_issue_zeroout in setup_new_group_blocks", by accidentally dropping
the code which reserved the block group descriptor and inode table
blocks.

Thanks for tracking it down! After a fsck, I'm still seeing fs corruption,
unfortunately:

[177266.375628] EXT4-fs error (device dm-1): htree_dirblock_to_tree:586: inode
#12255304: block 88074025: comm rm: bad entry in directory: rec_len is smaller

[177266.376135] EXT4-fs error (device dm-1): empty_dir:1922: inode #12255304:

[177266.376360] EXT4-fs error (device dm-1): empty_dir:1922: inode #12255304:
block 88074026: comm rm: bad entry in directory: rec_len is smaller than
minimal - offset=0(8192), inode=0, rec_len=0, name_len=0

fsck didn't notice this problem, but walking the tree seems to trigger it. I've
been trying to clean it up by just removing the offending directory, but it I
figured I'd mention it since it seems to be a problem that fsck -f didn't see.

Kees, was this (comment #4) using your resize-corruption.sh patch?  After
applying the patch I've enclosed, I've rerun your script, and it showed no
problems.  I then mounted the testfs file system, and ran ls -lR on /mnt/test,
and still no problems...

Ted, no, sorry; I didn't mean to confuse. Those are just left-over corruption
from my initial fs hit. I just thought I'd report the fact that fsck didn't
notice this when cleaning up from the original corruption.

I.e. here's my timeline for this corruption:

resize
get errors in dmesg
umount
fsck -f (for half a day, cleans up tons)
mount
delete all of lost+found
continue using fs
more dmesg errors
umount
fsck -f (returns without error)
mount
continue using fs
still dmesg errors
rm offending directory completely
no more errors

So, it seemed like a flaw in fsck that it didn't find the bad directory, but
since it was related to the corruption introduced by this kernel bug, I thought
I'd bring it up in this thread.

Ah, thanks for the clarification.

Ok, I think I see what's going on.  It's a difference of how e2fsck treats a
case of rec_len == 0 for block sizes less than 64k compared to the kernel.  
It's an edge case, but it's one we should definitely fix.  Thanks for pointing
it out.

--- Comment #12 from Martin Steigerwald <Martin@Lichtvoll.de>  2010-12-30 13:47:11 ---
I had a corrupted ext4 yesterday after I made a ThinkPad T42 BIOS update while
I just let the kernel hibernate. The kernel consequently oopsed after resuming
after the BIOS update - well whether it did so consequently, but it did it, I
made a screenshot of it, some ACPI related stuff AFAIR. Now I wonder whether it
was me wanting to save boot and uptime causing the issue or whether it was the
online resize a few days before - and I just didn't notice it cause actually I
did not reboot since then before.

Can you have a short log at the following to see whether that might have been
the same online resizing issue? I'd just like to know what might have been the
cause for that filesystem issue - cause I doubt that my risk based approach of
doing the BIOS update could have caused such a corruption. I will use the
shutdown and reboot method on any subsequent BIOS updated anyway - that much I
learned.

I already recovered by rsync'ing changed files to my backup as far as possible
and then redoing Ext4 from scratch with mkfs.ext4 and then restoring from
backup. I do not have the old state available anymore as I do not have a spare
220 GB to dd the filesystem to.

Thus I just like to know whether the following hints at this online resizing
issue or not. I have full output logs available on request. This is with:

martin@shambhala:~> cat /proc/version 
Linux version 2.6.37-rc7-tp42-ata-eh-dbg-dirty (martin@shambhala) (gcc version
4.4.5 (Debian 4.4.5-8) ) #1 PREEMPT Wed Dec 22 11:41:20 CET 2010

Which is a plain 2.6.37-rc7 + a libata debug patch in order to get to the cause
of bug #25392.

Here is some excerpt of fsck.ext4 output:

Later on I tried my Debian Squeeze/Sid/Experimental installation, / was

Fehler beim Speichern Verzeichnis Block Informationen (Inode=13203847, Block=0,

After this Ext4 was not mountable at all:

shambhala:~#8> mount /home
mount: wrong fs type, bad option, bad superblock on /dev/mapper/shambhala-home,
       missing codepage or helper program, or other error
       Manchmal liefert das Syslog wertvolle Informationen – versuchen
       Sie  dmesg | tail  oder so

# 

I think it was this:

Dec 29 21:58:37 shambhala kernel: EXT4-fs (dm-1): ext4_check_descriptors:
Checksum for group 0 failed (16277!=0)
Dec 29 21:58:37 shambhala kernel: EXT4-fs (dm-1): group descriptors corrupted!
Dec 29 21:59:50 shambhala kernel: EXT4-fs (dm-1): warning: mounting unchecked
fs, running e2fsck is recommended
Dec 29 21:59:50 shambhala kernel: EXT4-fs (dm-1): mounted filesystem with
ordered data mode. Opts: (null)

But in my case it actually didn't mount it - at least I thought so, cause I saw
the error on the console.

I used fsck.ext4 again and canceled it right after it repaired those checksums
it complained about in dmesg:

shambhala:~#32> fsck.ext4 -y /dev/shambhala/home

After this I was able to mount it. Then I did the rsync thing as I wanted to
save as much of my new data since the last backup as possible. Despite the long
fsck.ext4 outputs I think almost all of the new files are accessible.

Hmmm, it seems I had Ext4 issue prior to that BIOS update yesterday:

Jup, 27th of December. Thats exactly when I enlarged /home by 20 GB.

I found some other issues on the way: Recovery mode of my Debian installation
did not work: On each keypress to enter my password it showed the passwort
prompt again.

All in all this didn't raise my confidence in the stability of Ext4 especially
as fsck.ext4 did not even complete due to a failed memory allocation. Thus is
seems 2 GB of RAM and 4 GB of RAM does not seem to be enough to fsck my 220GB
/home in some occasions at least.

I used Ext4 again nonetheless, as I do not yet want to use btrfs for /home on
my main notebook.

Hmmm, the test script produces different fsck.ext4 output. But then my Ext4
filesystem had about two days to grow the initial corruption. And the syslog
shows first problems on the 27th of December while I did the BIOS update
yesterday evening.

Martin Steigerwald's problem should be filed as a separate bug if he can
reproduce it.  It would also be nice if he gave us e2fsck transcripts in
*english*, and was very clear which e2fsck output came from which machine, and
exactly what was done on each machine that might have been related to problems
showing up.

If someone wants to translate this to english, and separate out his different
complaints into separate bug reports, that would be great.  But I don't think
the ext4 developers have time to try to decrypt his bug reports....

I'm going to close the original problem as fixed since the original problem was
fixed.

Well I pretty much think that it was the same resize bug, but then it might as
well have been the BIOS thing (although I doubt it).

FWIW it was one machine, that ThinkPad T42, but different fsck.ext4 runs. When
the fsck.ext4 ran till the out of memory error the filesystem was unmountable
afterwards. When I quitted it before I was able to mount it.

Sorry for not using LANG=C with fsck.ext4, but at that time all I wanted is to
have my data back - nothing else mattered.

Anyway should I face an issue like that again, I will open a reparate bug
report and only hint that it might be the same problem as some other bug. I
also try to remember to use LANG=C.

So leave closed - I believe I hit that resize bug and all is well again.
