AMD64 testing

AMD64 testing

[mjt]

Hi guys!

Now that I moved along to AMD64 and still have my home directory
as Reiser4, I have a big incentive to get this baby stable on Reiser4.

What bugs can I help to reproduce? What test cases are there?

Let's make this work, shall we :)

Hi,

I will get an AMD64 soon (hopefully this year) and will run 64bit
Gentoo on it. How has it been running overall, is it workable and not
crashing like every 5 minutes? Just want to get an idee because I can
then decide of I will go with Reiser4 root from the start or test on
separate partitions.

And if I can help in any way please let me know!

Thanks and regards,
Sander

After a time, you may find that "having" is not so pleasing a thing,
after all, as "wanting." It is not logical, but it is often true.

For the record, Ubuntu Warty/Universe here with some random stuff
pulled from Hoary.

I had crashing, but it was due to faulty hardware ;)

Seriously I haven't had any issues with my /home/mjt/ as Reiser4
so far. Tuxracer did crash once trying to open some .sav file,
but I was stupid and just deleted the file :P

I've had reiser4/AMD64, root and all, last for days without crashing.
Eventually I noticed that it always seemed to crash when working with a
large file and small files at the same time. To replicate this usage
pattern, I'd dd a huge file from /dev/zero while compiling a kernel. The
kernel compilation is a good way of testing for corruption, too. If the
source fails to build after a crash, it's probably corrupt and you can
check your md5sums. Anyway, I've been running the following two commands
from a kernel source tree simultaneously:

for i in `seq 1 20` ; do make mrproper ; zcat /proc/config.gz > .config ;
make ; echo $i ; done

for i in `seq 1 5` ; do dd if=/dev/null of=large_file bs=1M count=20k ; rm
large_file ; echo $i ; done

Eventually, these two commands always cause a hard lock, or with debugging
enabled, a panic. I get the same results if dd runs on a different
filesystem on the same drive. Either command alone runs many iterations
with no signs of stopping, and both commands run on any other filesystem
simultaneously.

what fsck.reiser4 r/o check reports?

Hi,

Well, there're a few things you ought to try.  First off you'll need 
Alex's reiser4/AMD64 patch, which you can get at 
http://marc.theaimsgroup.com/?l=reiserfs&m=110219571330701&w=2 and then 
you probably ought to try Jake's resier4 killing commands, those're at 
http://marc.theaimsgroup.com/?l=reiserfs&m=109947213108486&w=2.

About the status of reiser4 on AMD64, well, you can find a lot more in 
those two threads.  In brief, I'm currently running a full system entirely 
on entirely reiser4, aside from /boot, and it has been mostly stable so
far.
