Hi Bastien,

This really looks like a hung task detector report.
Several tasks are stuck in queue_log_writer(), waiting
to be woken up on the "journal->j_join_wait" event and
that never happens because the waker is also stuck.
The problem is your report doesn't show where the waker
is stuck, but the hung task detector reports it, it just
did before or after the chunk you've posted.

If you could provide me the entire report, I could fix this
easily.

There are three places that can do this wakeup:

- reiserfs_allow_writes()
- wake_queued_writers()
- do_journal_end()

So it would be really great if you could select the following
config options:

CONFIG_REISERFS_CHECK
CONFIG_PROVE_LOCKING
CONFIG_DEBUG_SPINLOCK_SLEEP
CONFIG_DEBUG_MUTEXES
CONFIG_DEBUG_SPINLOCK
CONFIG_FRAME_POINTER
CONFIG_DETECT_HUNG_TASK

and try to reproduce the problem. You need to wait 3 minutes after
the lockup. And then, dmesg must contain everything I need to
fix this.

Thanks a lot in advance!

Without debugging enable lock up take about 30 minutes to occurs but
are really hard to reproduce with debugging on

Ok, this time I don't have the feeling that a deadlock between reiserfs lock and
another lock is involved.

We entered queue_log_writer() and then waited for someone to call do_journal_end()
to testify he finished his job with the journal.

But somehow that didn't happen. Or may be we called queue_log_writer() but we shouldn't,
thinking there was a writer already but there wasn't. Or there is a crazy race somewhere.

On which kernel do you see this? Do you know a kernel on which you've never seen it.
Were you running something specific to trigger this deadlock?

Thanks!

Nothing specific but it is trigger by kmail reading my mail each time...

How do you know you reproduced it? You had a crash before using SysRq?
Or you felt a deadlock or so?

What's interesting is that report is that there is no blocked task
that holds the reiserfs lock.

So I really feel the problem is that someone opened the journal but did not
release it.

How hard is it to reproduce now? If it's not so hard or haphazard, we should
start a bisection. Otherwise I think we'll need to do some tracing and this
is going to take several tries :)

Could you add a virtual lock for testing this hypothesis ? This lock
will be held during journal opening and releasing during journal
closing, using lockdep for testing this hypothesis ?

That's a good idea. But we can get the same result with traces more easily.
Plus I would like one more level of details about the origin of the issue.
We shouldn't skimp on dumping informations, given how hard it is to
reproduce ;)

So here is a patch that inserts some debug tracing points in the journal
opening and journal closing points, so that we can find if there is any
imbalance here, namely to find if the problem is some path that forgets
to close the journal (calling do_journal_end()).

But the reason could be something else. Like for some reasons writers
queue themselves waiting when they shouldn't.
So I've inserted two more points that will let us know why the hung tasks
have put themselves in queue.

This all should narrow down the possible origins of the issue.

You will need to select CONFIG_TRACING. Just select

Kernel Hacking
Tracers
[*] Trace process context switches and events

Or whatever option inside Tracers menu.

And when your problem triggers, type the sysrq combination
to dump ftrace buffers: Sysrq z

Ah and also boot with the ftrace=nop parameter, this will give you
enough size for the buffer, although I guess the default size should
be enough but we never know.

Thanks.

I Should add that some unrelated file but opened file are
overwritten.. For instance an xml file opened by akregator was
overwritten by a perl file opened under emacs during the crash...

This bug seems pretty serious and I have no idea to explain this behavior...

Any news of this bug ?

Can I help ?

[Frederic Weisbecker]

Hi Bastien,

Sorry for the time I've been away.

Yeah do you have CONFIG_REISERFS_CHECK? I just would
like to ensure we are not missing this important source of
information.

I'm puzzled because, given the traces, your opening and closing of the journal are
well balanced.

You have a writer queued and stuck but I see no trace of it in the traces stream.
I only see well balanced journal operations, including journal closing that would have
woken your queued writer.

A theory could be that your queued writer was waiting for someone to close the journal,
which finally happen but actually several minutes later, after there was many
journal opening/closing that overwrote the old trace containing the queueing of
the stuck writer.

I don't know what to do yet. I need to think more about it.

Could we do the stuff I have sugested at first ? use lockdep to track
journal open,/close using fake lock ?

BTW it seems that someone experiment this confition on ext3. I could
do more testing if you want, and I will run xfstests in order to see
if I could reproduce more quickly

About the corruption, I'm not sure it's the same problem. It's hard to
tell yet.

Which kernel are you running by the way?

I don't think it's not an adapted test. Lockdep is useful to detect lock inversion
scenarios but that's not very useful to detect a lock that takes too much time
to be released. For that we have the hung task detector, whose report we already
have.

I'm not sure the file corruption and the deadlock are linked. But
may be xfstest can provoke the deadlock (or the file corruption)
more quickly. It's pretty good at stressing file systems.

This could confirm the theory that someone has opened the journal and
spent way too much time before releasing it. Or something else.
In any case tell me, there are other tests we can run.

I have reported the whole stuff. But because my log need to go to my

You could reproduce quite easilly using with a lot of git pull in

Ah. I'm going to try that.
Can you perhaps send us your .config, in case it happens only on some
specific set. And also your options passed to mount reiserfs in /etc/fstab ?

I have a box currently running two parallel loops of git pull.
It has run for two hours now and nothing happened, I'm going to
let that wheel run the whole night and see tomorrow.

In the meantime I'm preparing another box with more CPUs to run
more parallel git pull. Hopefully I could stress it enough to
reproduce.

As mentionned by thomas I do not know why but running kmail fetching
an imap account in parallel of git increase the lookup rate.

Thanks for trying to reproduce.

Do you achieve to reproduce it ?

Do you want I test something ?

So I've run 8 parallel loops of git reset / git merge in 8 different
repos during 2 days but I've been unable to reproduce.

I'm going to retry the same with kmail. What kind of thing do you make
with kmail for this to trigger? Can you also resend me your config
because I can't retrieve it from our discussion.

Thanks.

I only retrieve every minutes a big imap account on gmail.
I do nothing else

The config is the same than debian standard kernel + debug reiserfs
option. Arch is amd64. Will send you in reply of this email

Thanks for trying to reproduce.

Note that my home directory (where lockup occurs frequently has
rw,nosuid,nodev,relatime,user_xattr,acl options.

May be this bug is trigered by combinaison of relatime and acl ?

Seems also that <solstic...@gmail.com> is hitting the same bug...

I don't know if it's the same bug because I never had problem with
kernel before 2.6.38.2. I have the problem with 2.6.38.3 too
but it never happened with 2.6.36 or 2.6.37 archlinux default kernel

I have downgraded to 2.6.37.5 and I have no problem so far.

/home (reseirfs fs) is mounted with defaults,nodev,relatime,user_xattr
options

My latest call trace with 2.6.38.3 with default archlinux configuration
of the kernel
