Hi
I have been starting to get some of the machines here on 2.6.0 (curently
test11). On one of them I got this kernel message:

It seems that this bug is related to a directory found on a xfs partition
with lots of entries (several thousands). I didnt got any message like
thos on some other systems which dont have such directories with many file
entries. Any 'ls' I try in that directory and any other process trying to
list its contents gets stuck in 'D' state.
I have attached .config file and here is what ver-linux says:
Linux status 2.6.0-test11 #1 SMP Tue Dec 2 17:19:31 EET 2003 i686 unknown

Nathan,
you're not off the hook yet. This is a smoking gun on XFS, and this time
with a big clue: large directories, and a low-memory situation.

Also, this time the config file doesn't have any MD/RAID support according
to the attachment:
# Multi-device support (RAID and LVM)
#
# CONFIG_MD is not set
so it looks like the XFS and MD issues really are totally unrelated.
Basically, as far as I can see a pattern, we have:
- MD/RAID causes a double bio free, and as a result we see the reports of
slab corruption from people who have slab debugging enabled.
- the XFS case causes some kind of "struct page" corruption, and as a
result we see the "Bad page state" messages followed by an eventual
oops due to corrupted page lists.
Two different bugs, two different behaviours. It's just that some people
have _both_ ;)
Mihai: the oops itself is in this case not very telling, since it's just a
result of corruption of some fundamental data structures (probably
somebody using a page cache page after having free'd it - and it probably
only shows up when memory gets low and pages have to be cleaned). Can you
tell Nathan more about the filesystem setup (block size, as much as
possible about the affected directory, etc).

Hi Linus
First of all thanks for the answer!

Sorry to have misguided you guys in the first post. After rebooting the
machine I have some more information, the actual directory size its about
some hundred entries (~400) and not thousands as I previously speculated
(I didnt know the exact number until I could ls it and I couldnt do that
until I had to reboot the machine).
Beeing just several hundred entries I know that I have at least one more
2.6.0-test11 machine (SMP, no MD but hw DAC960 RAID) with more entries in
one directory and I didnt got any such message (yet), it has only 5 days
uptime, we will see if I get anything there too. It could be just that on
the other machine I dont have much action happening in the directories
with many entries. The machine which got the kernel error has a lot of
things going in that directory with many entries (mostly stats gathered
every 5 mins from cron with mrtg and written to binary image files).
However I have some more usefull (I hope) information about the subject.
Before rebooting I wanted to first install a do_brk() patched 2.4.21-xfs
kernel with lilo. Unfortunetly lilo stuck in a fsync() call after writing
to screen that it did added all kernel images to MBR as configured in
lilo.conf. When I booted I had no problem to boot from the new do_brk()
fixed kernel so lilo seems it did the job, I dont know why it stuck
in fsync().
ctrl-alt-del didnt do the trick (I had online ssh session on the machine
which was working , I could do ps ax, vmstat etc, but probably init was
doing something which also stuck in D state) so I had to reboot it "hard".
After power on, one coleague complained that a file on which he worked a
couple of minutes before I took the machine down had NULL bytes instead of
actual content. I know that "dirty" data gets flushed to disk every 30
seconds so this seems a little bit strange (in general I know that XFS
leaves NULL bytes in files modified just before a unclean reboot but this
file was modified some 5 minutes before the "hard" reboot).

Yep, Im very conservative to the features I use in the kernel :)

Ok.

Mount options are "rw,noatime".
Please let me know if you need any other infos. Thanks!

Still, its a clue - all metadata I/O in XFS goes though the
pagebuf code, so we're looking in the right place.

Was your filesystem near full? There was a 2.4 deadlock fixed
recently which could be what you hit there.

You'll want a more recent 2.4 XFS kernel I suspect - Steve made
several improvements in this area awhile back.

Sure does.

OK, looks like a default mkfs then (with an old-ish mkfs binary)?
Newer mkfs' will give you a better AG layout and unwritten extents
would be turned on - not relevent to this problem at all though.
An "ls -ld" and "xfs_bmap -v" on the directory would also provide
me a bit more info to work with -- thanks!
I have a few ideas about what this might be, let me stew on those
for a bit and try a few things.
cheers.

No it wasnt. It has a ~50% usage.

Ok. I know about improvements since XFS 1.1 and I assumed that using a
recent (ie 2.6.0-test11) kernel the XFS bits with it whould be recent and
such have those improvements.
> OK, looks like a default mkfs then (with an old-ish mkfs binary)?
True. Its a general /var partition, there waasnt any interest in giving
mkfs paramteres for it.

Ok, noted :)
