want to help do some debuging

[Jelle de Jong]

Hello everybody,

I am new to this list, so i would like to thank everybody for there hard
work on the fuse system.

I am a heavy user of sshfs, and would like to include it as a service to
our thick clients as remote storage/sharing option. I have been testing
its stability for the last year intensive and I got some major problems
like, lost connections, freezing sshfs mounts, requiring to killall ssh
and sshfs or complete reboots. Freezing ssh servers behaving as some
firewall block because something a sshfs mount is doing. The problems
mostly accure when using sshfs heavy with multiple programs -> playing
dvd, ogg files, writing data to the remote share.

So loads of issues and no real bug reports to define the behind
problems. I would like to help create some good bug reports.

I use debian sid and use the following command to mount the root
file-system.

ssh -x -a -oClearAllForwardings=yes -2 user@... -s sftp

/usr/bin/sshfs -s -o allow_root -o sshfs_sync user@...:/
/mnt/domain-server-user/root/

The command runs in the background and is started when a network
connections comes up (if-up) system.

How can I create an automatic logfile that the developers can use for
debugging?

Tanks in advance,

Jelle

Yepp, same issues here, and I'd also like to make a logfile to aid
developers in debugging.  I use sshfs everyday here in FreeBSD. =)

I really want to create some good bugreports and find the problems that
are causing our instable sshfs. I have really painful freezing client
sshfs systems that drag down a complete healthy server that is
connecting the client!

I really want to help, can somebody tell me how to make full automatic
bug reports so i can save them when a crash surfaces.

Thanks in advance,

Jelle

You cannot make automatic bug reports. The following might be helpful
as a basis for a *manual* bug report though:

 - compile sshfs with debugging symbols
 - use the -dfs parameters when starting gdb and save the output
 - when it crashes, create a backtrace as described on
   https://wiki.ubuntu.com/Backtrace


Best,

   -Nikolaus

Thank you Nikolaus for answering my mail.

I downloaded the sshfs-fuse source package for my distribution Debian
sid and did a configure --help to see what options i sould use to
compile sshfs with debugging symbols. However I did not found any info
in the output regarding debugging?

Can you tell me with what options I should use to compile sshfs with
debugging support? I want to create a sshfs-fuse-debug package for
Debian sid.

CFLAGS="$(CFLAGS)" ./configure --host=$(DEB_HOST_GNU_TYPE)
--build=$(DEB_BUILD_GNU_TYPE) --prefix=/usr
--mandir=\$${prefix}/share/man --infodir=\$${prefix}/share/info
--disable-sshnodelay

Kind regards,

Jelle

You should be able to build a debian package with debugging symbols as
follows:

# export DEB_BUILD_OPTIONS="debug nostrip noopt"
# sudo apt-get install devscripts fakeroot
# sudo apt-get build-dep sshfs-fuse
# fakeroot apt-get source -b sshfs-fuse

HTH,

Or where you referring to the gcc -g flag for debugging?

In that case the debian sid package is already build with debugging
support? This is a part of the debian/rules file:

CFLAGS = -Wall -g

ifneq (,$(findstring noopt,$(DEB_BUILD_OPTIONS)))
        CFLAGS += -O0
else
        CFLAGS += -O2
endif

config.status: configure
        dh_testdir
        CFLAGS="$(CFLAGS)" ./configure --host=$(DEB_HOST_GNU_TYPE)
--build=$(DEB_BUILD_GNU_TYPE) --prefix=/usr
--mandir=\$${prefix}/share/man --infodir=\$${prefix}/share/info
--disable-sshnodelay

Kind regards,

Jelle

Which version?  Quite serious bugs have been fixed in sshfs during the
last year, so first of all you should try upgrading to the latest
version, and see if these mysterious problems are still present.

Thanks,
Miklos

Thanks you for your response,

Yesterday i put a lot of work in the creation of new debug packages for
debian sid, i hope they will be accepted soon.

http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=491210

I attached deb files in the report.

This is my current version
sshfs --version
SSHFS version 2.0
FUSE library version: 2.7.3
fusermount version: 2.7.3
using FUSE kernel interface version 7.8

With standard user file open save close operations. I don't have real
issues, but with heavy load like caching video it seems to go wrong. I
have the idea it may have something to do with the -s option i use in
sshfs. But more testing is nessesary.

Now i created the sshf-fuse-dbg package, i have to find a workable way
to backtrace sshfs process while playing multimedia trough a sshfs
system. (hints welcome)

Kind regards,

And thanks for all the hard work,

Jelle

Start gdb and attach it to the running sshfs process, as explained on
the ubuntu wiki.

Best,

Thank you for your message,

Yesterday I did a debug session, loaded gdb and attached sshfs and
continued the process (see attachment).

I start watching a dvd over my sshfs connection and after 16 minutes the
player froze unrecoverable. I did a killall -9 totem-xine. Then i tried
to access my sshfs mount but this one was also completely frozen hanging
my thunar file-manager. So i did a killall -9 sshfs. This made my system
working again. I did a back-trace with gdb but no info came out of it. I
remounted my sshfs and watched the rest of the dvd without problems.

Any idea's how to provide more debug info?

Thanks in advance,

Jelle

Yeah, you need to do the backtrace *before* killing the process.
Otherwise there is nothing left that gdb could do any work on.

So *before* you do any killall calls, create the backtraces.


Best,

Thank you again for the information,

Last to days I gathered three backtrace reports after three sshfs
freezes. I attached the reports as attachments.

Is this information that you can use to find the problem?

/usr/bin/sshfs -s -o allow_root -o sshfs_sync user@...:/ /mnt/domain-server-user/root/
ssh -x -a -oClearAllForwardings=yes -2 jelle@... -s sftp

steps to reproduce:
1: mount the sshfs mount with the sshfs mount command
2: go to directory with video dvd iso images
3: mounted the dvd in the same directory
4: loaded the video_ts direcorty in totem-xine
5: start waching the movie
6: *sometimes* the sshfs just freezes and does not respond anymore
7: i have to kill sshfs and when possible remount the sshfs or reboot the client computer
