reiserfs autofix?

reiserfs autofix?

[putter]

Hi,
I am kernel newbie, especially with logging filesystems.
Now I am using Mandrake 7.1 with 2.4.3 kernel and imon patch
and NVidia drivers compiled into the kernel.
Now, all my partitions are ReiserFS. I usually play quake once
or twice a day. Sometimes graphics subsystem freezes up, so it takes
keyboard input. Caps and Numlock are working fine, unless I try to kill
X with ctrlalt-backspace. So I reset my machine with hardware switch.

here is the interesting part... after I reset my machine like that,
some files start to appear corrupted. Segmentation faults etc. 
Isn't reiserfs suppose to be safe? NOW, THE REAL SPOOKY PART:
I reboot my machine with normal procedure, like shutdonw -r now,
and on other boot, corrupted files FIX themselves. Any insight?
I think it is rather unacceptable...
cheers,
	pavel

     ^^^^^^^^^^^^^^^

The binary only nvidia drivers make it a bit hard for us to debug.

Check your /var/log/messages.  You probably have messages from reiserfs.
Send along an lspci so we can see what your hardware is.

I think I have tracked down the problem to the card itself. My machine is on @ graphics mode all the time,
like 24hrs a day, and it seems that it is somewhat taxing on the cards performance. So now I switch down to
text mode, everytime I leave the machine. How did I find out? I placed my finger of heatsink of my GeForce DDR.
It was HOT! Fan works alright, so if I was to run computer a while, stress accumilates, and when I run GeForce
understress of maximum resolutions, it craps out. So much for NVidia eh?

BTW, I don't question graphical subsystem crashes. I question reiserfs that suppose to leave my partitions
in consistent state, no matter how trigger happy with power switch I am, or is my judgement is clouded? >=)

So here's details....: Offending reiserfs messages, after last boot.

Do a search through the kernel arcvhies for nvidia.  The crashes could just
be the driver.  But heat is always a problem, add fans ;-)

After a crash, reiserfs only cleans up after itself.  If someone else went
in and hosed the metadata (nvidia, bad drive, controller, ide fun with
via), you've still got bad blocks.

This is one possible reason that we've seen more reports than ext2 has.
After a crash, ext2fsck fixes _whatever_ was broken.  log replay in
reiserfs only fixes the operations that were in progress when the system
crashed.

Anyway, those messages show that you've got metadata corruption.  grab the
latest reiserfsprogs from ftp.reiserfs.org and run reiserfsck -x (after
backing things up).

You are using the NVIDIA closed driver. Please duplicate the problem without
that driver or take it up with NVIDIA not the kernel list
