List corruption with corrupted xfs image
Hi,
with the image at http://www.cccmz.de/~snakebyte/xfs.42.img.bz2
and the following commands:
mount -o loop -t xfs xfs.42.img /media/test touch /media/test/file >/dev/null 2>&1
ln -s /media/test/file /media/test/fileb >/dev/null 2>&1 mkdir /media/test/dir1 >/dev/null 2>&1
cp /media/test/file /media/test/dir1 >/dev/null 2>&1 umount /media/test
I get a list corruption and dead box

cp /media/test/file /media/test/dir1 >/dev/null 2>&1 umount /media/testI get a list corruption and dead box
The oops is in code we don't have around anymore in 2.6.29-rc, but I'll give it a try on more recent code.
Thanks a lot!

Hi,
with the image at http://www.cccmz.de/~snakebyte/xfs.42.img.bz2
and the following commands:mount -o loop -t xfs xfs.42.img /media/test touch /media/test/file >/dev/null 2>&1
ln -s /media/test/file /media/test/fileb >/dev/null 2>&1 mkdir /media/test/dir1 >/dev/null 2>&1

I tried this again with todays -git and got a different trace, but I guess the trace is where the corruption was detected, not where it occured.
