[Bug 12224] New: journal activity on inactive partition causes inactive harddrive spinup

           Summary: journal activity on inactive partition causes inactive
                    harddrive spinup
           Product: File System
           Version: 2.5
     KernelVersion: 2.6.27.6
          Platform: All
        OS/Version: Linux
              Tree: Mainline
            Status: NEW
          Severity: low
          Priority: P1
         Component: ext3
        AssignedTo: fs_ext3@kernel-bugs.osdl.org
        ReportedBy: csights@fastmail.fm


Latest working kernel version: 2.6.27.5
Earliest failing kernel version: 2.6.27.6
Distribution: Debian stable with custom compiled vanilla kernel

Problem Description:
    Activity on one partition (hda1) causes kjournald to also write to another
partition (sda1).  This in turn causes the harddrive which contains sda1 to
spinup or not spindown.
    I've activated laptop-mode using laptop-mode-tools. hda1 and sda1 are both
formatted with ext3.
    On unaffected kernels (e.g. 2.6.27.5) btrace produces no output.  On
affected kernels (e.g. 2.6.27.6, 2.6.27-rc7) btrace produces output as below.

/dev/hda1 on / type ext3 (rw,noatime,errors=remount-ro,commit=1209600)
tmpfs on /lib/init/rw type tmpfs (rw,nosuid,mode=0755)
proc on /proc type proc (rw,noexec,nosuid,nodev)
sysfs on /sys type sysfs (rw,noexec,nosuid,nodev)
udev on /dev type tmpfs (rw,mode=0755)
tmpfs on /dev/shm type tmpfs (rw,nosuid,nodev)
devpts on /dev/pts type devpts (rw,noexec,nosuid,gid=5,mode=620)
debugfs on /sys/kernel/debug type debugfs (rw)

Steps to reproduce:
    1. start "btrace /dev/sda"
    2. begin compiling kernel
    3. within seconds btrace begins output similar to below.


Thanks for all your work!  Sorry if I've misplaced blame for this undesirable
change in behavior.

I think I've seen other reports of this.  Maybe it was you.

OK, that's a huge mess because bugzilla went and wordwrapped it.  Let
me fix it:

I'm not familar with btrace.  What are we looking at here?

The only likely commit I see in
ftp://ftp.kernel.org/pub/linux/kernel/v2.6/ChangeLog-2.6.27.6 is "ext3:
wait on all pending commits in ext3_sync_fs", but I don't see how it
could cause this.

Andrew, it's blktrace/blkparse output, basically.  blkparse(1) manpage
has the details.

maj,min cpu  seq  time           pid   act rwbs off+len
8,0      0    1   0.000000000    1109   A   WS 14375 + 8 <- (8,1) 14312

... etc

I'm not sure it gives us enough info; all we see is that there was an IO
on sdb (from sdb1)

I might suggest

# sysctl -w vm.block_dump=1

to see if you get any info about inodes on sda1 being dirtied.

(Also, I didn't see any info about sda1 in the posted fstab...)

Andrew, it's blktrace/blkparse output, basically.  blkparse(1) manpage
has the details.

maj,min cpu  seq  time           pid   act rwbs off+len
8,0      0    1   0.000000000    1109   A   WS 14375 + 8 <- (8,1) 14312

... etc

I'm not sure it gives us enough info; all we see is that there was an IO
on sdb (from sdb1)

I might suggest

# sysctl -w vm.block_dump=1

to see if you get any info about inodes on sda1 being dirtied.

(Also, I didn't see any info about sda1 in the posted fstab...)

Re: [Bug 12224] New: journal activity on inactive partition causes inactive harddrive spinup

I've looked at the changes between 2.6.27.5 and 2.6.27.6, and I don't
see anything that might explain such a regression.  Indeed, there's
only one patch between .5 and .6 that even touches ext3, and the patch
seems pretty innocent.

Is /dev/sda1 even mounted?  It doesn't included up in your /etc/mtab
listing.

The only thing I can suggest is to try 2.6.27.6 with the only patch
that touches ext3 reverted (i.e., unapply it with patch -R).  If the
problem still shows up, I would suggest getting the linux-2.6.27.y
tree from:

git://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-2.6.27.y.git

And then doing a git bisection search to try to find the guilty
commit.

commit a0b8bfb34743b6e6c2bb06ad5a270590d90270f7
Author: Arthur Jones <ajones@riverbed.com>
Date:   Fri Nov 7 00:05:17 2008 +0000

    ext3: wait on all pending commits in ext3_sync_fs
    
    commit c87591b719737b4e91eb1a9fa8fd55a4ff1886d6 upstream
    
    In ext3_sync_fs, we only wait for a commit to finish if we started it, but
    there may be one already in progress which will not be synced.
    
    In the case of a data=ordered umount with pending long symlinks which are
    delayed due to a long list of other I/O on the backing block device, this
    causes the buffer associated with the long symlinks to not be moved to the
    inode dirty list in the second phase of fsync_super.  Then, before they
    can be dirtied again, kjournald exits, seeing the UMOUNT flag and the
    dirty pages are never written to the backing block device, causing long
    symlink corruption and exposing new or previously freed block data to
    userspace.
    
    This can be reproduced with a script created
    by Eric Sandeen <sandeen@redhat.com>:
    
    	#!/bin/bash
    
    	umount /mnt/test2
    	mount /dev/sdb4 /mnt/test2
    	rm -f /mnt/test2/*
    	dd if=/dev/zero of=/mnt/test2/bigfile bs=1M count=512
    	touch
    	/mnt/test2/thisisveryveryveryveryveryveryveryveryveryveryveryveryveryveryveryverylongfilename
    	ln -s
    	/mnt/test2/thisisveryveryveryveryveryveryveryveryveryveryveryveryveryveryveryverylongfilename
    	/mnt/test2/link
    	umount /mnt/test2
    	mount /dev/sdb4 /mnt/test2
    	ls /mnt/test2/
    	umount /mnt/test2
    
    To ensure all commits are synced, we flush all journal commits now when
    sync_fs'ing ext3.

Yes, that was me.  :)

        I waited until 20:02, then ran:

# sysctl -w vm.block_dump=1; btrace /dev/sda | logger -s

        and switched to a different terminal and ran in the linux kernel
directory 
(on hda1):

# make clean

        I waited until "btrace" indicated activity on sda1, then stopped the
"make 
clean".  If you would like me let it run a few more seconds let me know.
        Below is the output from /var/log/syslog.  The btrace and block_dump
output 
is interleaved.  Lines containing "logger" are from btrace.

Oops!  copied the "mount" output when sda wasn't mounted.  Here is the output 
of "mount" current when the above output was generated:

[Bug 12224] journal activity on inactive partition causes inactive harddrive spinup

I've looked at the changes between 2.6.27.5 and 2.6.27.6, and I don't
see anything that might explain such a regression.  Indeed, there's
only one patch between .5 and .6 that even touches ext3, and the patch
seems pretty innocent.

Is /dev/sda1 even mounted?  It doesn't included up in your /etc/mtab
listing.

The only thing I can suggest is to try 2.6.27.6 with the only patch
that touches ext3 reverted (i.e., unapply it with patch -R).  If the
problem still shows up, I would suggest getting the linux-2.6.27.y
tree from:

git://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-2.6.27.y.git

And then doing a git bisection search to try to find the guilty
commit.

Regards,

                                        - Ted
commit a0b8bfb34743b6e6c2bb06ad5a270590d90270f7
Author: Arthur Jones <ajones@riverbed.com>

    ext3: wait on all pending commits in ext3_sync_fs

    commit c87591b719737b4e91eb1a9fa8fd55a4ff1886d6 upstream

    In ext3_sync_fs, we only wait for a commit to finish if we started it, but
    there may be one already in progress which will not be synced.

    In the case of a data=ordered umount with pending long symlinks which are
    delayed due to a long list of other I/O on the backing block device, this
    causes the buffer associated with the long symlinks to not be moved to the
    inode dirty list in the second phase of fsync_super.  Then, before they
    can be dirtied again, kjournald exits, seeing the UMOUNT flag and the
    dirty pages are never written to the backing block device, causing long
    symlink corruption and exposing new or previously freed block data to
    userspace.

    This can be reproduced with a script created
    by Eric Sandeen <sandeen@redhat.com>:

        #!/bin/bash

        umount /mnt/test2
        mount /dev/sdb4 /mnt/test2
        rm -f /mnt/test2/*
        dd if=/dev/zero of=/mnt/test2/bigfile bs=1M count=512
        touch
       
/mnt/test2/thisisveryveryveryveryveryveryveryveryveryveryveryveryveryveryveryverylongfilename
        ln -s
       
/mnt/test2/thisisveryveryveryveryveryveryveryveryveryveryveryveryveryveryveryverylongfilename
        /mnt/test2/link
        umount /mnt/test2
        mount /dev/sdb4 /mnt/test2
        ls /mnt/test2/
        umount /mnt/test2

    To ensure all commits are synced, we flush all journal commits now when
    sync_fs'ing ext3.

Dec 14 20:02:18 localhost kernel: kjournald(1109): WRITE block 12520 on sda1

is the first thing I see in the log above, with no indication of anything else
on sda1 before that.

If you let the system just sit idle, do you get sda1 hits from the sysctl
and/or blktrace?

------- Comment #7 from csights@fastmail.fm  2008-12-15 13:49 -------
Hi,
        Following Ted's suggestion, I began with 2.6.27.6 and then reversed the
patch 
for commit a0b8bfb34743b6e6c2bb06ad5a270590d90270f7.  This "fixed" the 
problem such that activity on hda1 no longer caused kjournald to write to 
sda1.




> Is /dev/sda1 even mounted?  It doesn't included up in your /etc/mtab
> listing.

Just to confirm, I posted the wrong mtab previously.  sda1 is mounted during 
my tests.  This is how it looks:

/dev/hda1 on / type ext3 (rw,noatime,errors=remount-ro,commit=1209600)
tmpfs on /lib/init/rw type tmpfs (rw,nosuid,mode=0755)
proc on /proc type proc (rw,noexec,nosuid,nodev)
sysfs on /sys type sysfs (rw,noexec,nosuid,nodev)
udev on /dev type tmpfs (rw,mode=0755)
tmpfs on /dev/shm type tmpfs (rw,nosuid,nodev)
devpts on /dev/pts type devpts (rw,noexec,nosuid,gid=5,mode=620)
/dev/sda1 on /mnt/sda type ext3 (rw,noatime,commit=1209600)
debugfs on /sys/kernel/debug type debugfs (rw)

        I only copied the lines from the log during the short compile "test".
        Here is another test which is a little more clean, using 2.6.27.6
(without 
the commit mentioned above reverted). 

        First unmount, then remount /dev/sda1 to flush the filesystem caches:
# umount /dev/sda1; mount /mnt/sda; btrace /dev/sda | logger -s

        then switch to another console and restart laptop mode (to change the
commit 
time on sda1):
#/etc/init.d/laptop-mode restart

        Finally generate some activity on hda1.  ("make menuconfig")
        The following is syslog from the mount of /dev/sda1 (on /mnt/sda) until
"make 
clean" finished:

        If I let the system sit idle using 2.6.27.5 (the last unaffected 
version) 'btrace /dev/sda' shows no activity, even if there is activity on 
hda1.
        If I let the system sit idle using 2.6.27.6 (the first affected 
version) 'btrace /dev/sda' shows kjournald doing something with sda1 if there 
is activity on hda1.  If hda1 is inactive then there is also no activity on 
sda1.

Thanks!

Hi all,
        You might be interested to know that this problem can be reproduced by
using 
an ext3 image file mounted loopback.  (I.e. You don't need a separate 
harddrive or partition in order to reproduce the problem.)

Are the laptop-mode tools doing remounts behind your back?

The only way I see this is if I do "mount -o remount /"; then I see kjournald
activity on other ext3 filesystems.  I'll dig into that.

I don't think so: I was able to reproduce this bug using an ext3 loopback 
mounted file.  laptop-mode-tools does not touch loopback devices as far as I 
can tell.  Here is my laptop-mode.conf:

> #

> # Separate them by a space, e.g. HD="/dev/hda /dev/hdb". The default is a
> # wildcard, which will get you all your IDE and SCSI/SATA drives.

        And here is the loopback mount:

/tmp/ext3Image on /mnt/loop type ext3 
(rw,noatime,loop=/dev/loop/0,commit=1209600)

        (I set the commit=1209600 and noatime by hand on the loopback mounted
ext3 
image file.)

        Since I'm not a kernel hacker, I don't know how the code is structured.
 It 
feels like the kernel commit code is not fully separated by device (or 
partition). When the active partition's journal is "synced" it triggers 
activity on other partitions, even if the other partitions aren't active.

C.

------- Comment #12 from sandeen@redhat.com  2008-12-18 15:02 -------
In a nutshell, with laptop mode on, we go down this path:

static void laptop_timer_fn(unsigned long unused)
{
        pdflush_operation(laptop_flush, 0);
}

static void laptop_flush(unsigned long unused)
{
        sys_sync();
}

which gets us to the new 

static int ext3_sync_fs(struct super_block *sb, int wait)
{
        sb->s_dirt = 0;
        if (wait)
                ext3_force_commit(sb);
...

which is then committing empty transactions.  Seems like we should be smart
enough to skip committing transactions w/ nothing in them...?

Sure!
        I manually patched 2.6.28.  btrace showed lots of output as above. 
However, 
I didn't wait to see if the observed activity affected the drive spinup/down 
b/c I thought maybe patching 2.6.28 was not proper.
        I don't know how to git the right kernel sources to patch.  Could you
prepare 
a patch against an RC (or in some other way hold my hand)?  Or I could wait 
for some RC which includes the patch already.

Sorry for my gimpiness,
        C.

        I applied the patch to 2.6.28....
        However there is still activity on the inactive partition (sda) if
there is 
activity on the other partition (hda).
        I've pasted the current output of 'btrace /dev/sda' in case it has
changed 
from before.

Yes, I have jbd-fix-return-value-of-journal_start_commit.patch and
revert-ext3-wait-on-all-pending-commits-in-ext3_sync_fs.patch queued
for 2.6.29.

The secret algorithm for determining this is to peek in the series file
(http://userweb.kernel.org/~akpm/mmotm/series) and see where I positioned the
patch:

Patches against ext3 have been posted by Jan Kara and have been sucked
into the mm tree.  I don't know if Andrew is planning on waiting until
the next merge window, or is planning on pushing it sooner given that
it is a regression.  (These supercede the ones currently posted by
Eric in the BZ entry.)

Similar patches have been posted against ext4, and I will be handling
them in the ext4 tree.
