2.6.29-rc2: XFS internal error XFS_WANT_CORRUPTED_GOTO
Hi All,
I've stepped into XFS issue/bug. Yesterday I've compiled 2.6.29-rc2 and no didn't found errors. Today I've booted my notebook and XFS bug have occurred. System reboot didn't helped, same error appeared.
Some info:

Hi All,
I've stepped into XFS issue/bug. Yesterday I've compiled 2.6.29-rc2 and no didn't found errors. Today I've booted my notebook and XFS bug have occurred. System reboot didn't helped, same error appeared.

so this happens every mount? Reproducible is good. How large is the filesystem (too large to extract elsewhere for analysis...?) (plus I suppose it'll be hard to get to it when you can't even boot....)

Hi All,
I've stepped into XFS issue/bug. Yesterday I've compiled 2.6.29-rc2 and no didn't found errors. Today I've booted my notebook and XFS bug have occurred. System reboot didn't helped, same error appeared.
Some info:
[1] config: http://pin.if.uz.zgora.pl/~difrost/linux-next/2.6.29-rc2.config
[2] kernel logs:
http://pin.if.uz.zgora.pl/~difrost/linux-next/2.6.29-rc2_XFS-bug.log

so this happens every mount? Reproducible is good. How large is the filesystem (too large to extract elsewhere for analysis...?) (plus I suppose it'll be hard to get to it when you can't even boot....)
XFS folks, I suspect the common link between all the reports of this bug is that they are on 32-bit kernels. I can't reproduce this on a 64 bit kernel, and I'm trying to get a 32-bit UML built right now to test this theory.
Cheers,
Dave.

Yep, 32-bits here. I've googled a while looking for some answer and it looks like it has happen before in various kernel version (no report regarding 2.6.29 AFAIR).

I'm doing about half of my testing on 32 bit x86, and I couldn't reproduce the detailed receipe in the kernel.org bugzilla yet.
Just curious: do you have CONFIG_LBD set?

Author: Christoph Hellwig <[email protected]> Date: Thu Oct 30 16:58:01 2008 +1100
[XFS] implement generic xfs_btree_delete/delrec
Make the btree delete code generic. Based on a patch from David Chinner with lots of changes to follow the original btree implementations more closely. While this loses some of the generic helper routines for inserting/moving/removing records it also solves some of the one off bugs in the original code and makes it easier to verify.

Applied. Thanks. Will do some tests with your script.

Yeah, it's more of a hack. If you drop the patch and just enable CONFIG_LBD it should be fine.

Please try the patch I posted this morning - it fixes the problem properly and shouldn't have this side effect.

[XFS] Long btree pointers are still 64 bit on disk
On 32 bit machines with CONFIG_LBD=n, XFS reduces the in memory size of xfs_fsblock_t to 32 bits so that it will fit within 32 bit addressing. However, the disk format for long btree pointers are still 64 bits in size.
The recent btree rewrite failed to take this into account when initialising new btree blocks, setting sibling pointers to NULL and checking if they are NULL. Hence checking whether a 64 bit NULL was the same as a 32 bit NULL was failingi resulting in NULL sibling pointers failing to be detected correctly. This showed up as WANT_CORRUPTED_GOTO shutdowns in xfs_btree_delrec.
Fix this by making all the comparisons and setting of long pointer btree NULL blocks to the disk format, not the in memory format. i.e. use NULLDFSBNO.

Hi All,
I've stepped into XFS issue/bug. Yesterday I've compiled 2.6.29-rc2 and no didn't found errors. Today I've booted my notebook and XFS bug have occurred. System reboot didn't helped, same error appeared.
Some info:
[1] config: http://pin.if.uz.zgora.pl/~difrost/linux-next/2.6.29-rc2.config
[2] kernel logs:
http://pin.if.uz.zgora.pl/~difrost/linux-next/2.6.29-rc2_XFS-bug.log
[3] most interesting part of log below.

so this happens every mount? Reproducible is good. How large is the filesystem (too large to extract elsewhere for analysis...?) (plus I suppose it'll be hard to get to it when you can't even boot....)
-Eric
Hi Eric,
funny or sad thing is that this happens while mounting only one of partitions (/home) which is:
$ df -h | grep /home /dev/sda5 20G 14G 6,0G 69% /home
This bug is quite strange, as I mentioned, first boot on new kernel went OK, next two resulted in such behavior. Now I'm running 2.6.29-rc2-12097-gf3b8436 and no bug here. Nevertheless I'm not fully happy, as it was seen before, the bug might still happen (will boot few times to test it and report back to you).
First yesterday buggy but went unnoticed so I've started fluxbox and firefox (errors seen in log), as usual, then found that sth is wrong. Second boot was also buggy than I've returned to old kernel where everything was OK ... nearly everything, cause firefox suddenly ,,forgot'' all configuration.
I will boot my notebook on all those 2.6.29-* kernel few times and maybe be able to reproduce that bug.

I've made some tests. Basically umount + mount (with time measurement):
$ for i in $(seq -s ' ' 1 20) ; do echo "[=> umount [$MNT]: $i" ; time umount
$MNT ; [ $? -eq 0 ] && echo "[=> mount [$MNT]: $i" && time mount $MNT || break ;
done 2>&1 | tee ~/${MNT##*/}_mount_git.logwhere MNT was set to three different partitions (all with XFS). Both on rc2 and git version, no bug appeared. If someone is interested (I've seen some delays in mounting before), some time results here:
http://pin.if.uz.zgora.pl/~difrost/linux-next/mount_logs/
I will still mess around so maybe it will appear once more than will try do some more tests (suggestions are welcome).
