Hi - this crash occured with Fedora 16 kernel 3.1.5-6.fc16.x86_64. The
message below appeared and the machine locked up with the hard drive on and
the keyboard lights blinking. Btrfs was running with compress-force=zlib on
a software raid md linear array (~5GB), around 50% full.

So I've got a daily snapshot of my /home subvolume. Due to a fat finger, I've
damaged a rather large file so I'd like to pull if from one of these snapshot
backups. I don't want to simply copy the file since it's many gigs and cp

Go through all extents of a file in a given [start,end) range and sum
for:
* regular extent: -block_len, size is already rounded up to blocks
* inline extents: length rounded up to 512
The range is start inclusive / end exclusive. For whole a file pass
0 and (u64)-1.
The values returned are

You would need to apply this patch to your kernel:

Is there any chance this patch gets in linux-next ?
I use this feature all the time and it never broke on me.

I found a solution, but requires a bit of setup.
Did you try:
echo force-unsafe-io /etc/dpkg/dpkg.cfg
stracing an apt-get update, it seems that --force-unsafe-io doesn't stop

Hi again!
Any hints about this one?
Since scrubbing worked okay on other machines, I can also redo the BTRFS
filesystem on this machine. Maybe it really has gained a corruption. (Still
scrubbing should not lock up the kernel hard, but…)
Thanks,
Martin
