I'll go run that and get you the output.
Thanks.
I can do the image dump, sure. I don't know how long it might take to
upload it somewhere though. Right now `btrfs fi df` shows about 2GiB
of metadata (it's a 120GiB volume). I'll see how large it ends up
after compression.
120G volume seems quite small, compared the images I received recently
(1T x2 RAID1 and 4T single).
With '-c 9' it shouldn't be too huge I think(The 1T raid1 is about 1G
metadata with -c9).
BTW, btrfs-image dump will have all the filenames and hierarchy, even
without its data,
it is still better considering your privacy twice before uploading.
Thanks,
Qu
Thanks for the quick response,
Daniel

Hi,
What's the btrfsck output? Without --repair option.
Also, if it is OK for you, would you please dump the btrfs with
'btrfs-image' command?
'-c 9' option is highly recommended considering the size of it.
This will helps a lot for developers to test the btrfsck repair function.
Thanks,
Qu

Hello,
After I had some brief stability issues with my computer, it seems
some form of metadata corruption took place in my BTRFS filesystem,
and now a particular file seems to exist, but I cannot access any
details on it or delete it.
If I try to `ls` in the directory it is in, that's what I get:
ls: cannot access string.h: No such file or directory
total 0
drwxr-xr-x. 1 danielkza mock 16 Nov 21 14:18 ./
drwxr-xr-x. 1 danielkza mock 6 Nov 21 14:18 ../
-?????????? ? ? ? ? ? string.h
If I try to delete it I get:
rm: cannot remove ‘string.h’: No such file or directory
I'm using kernel 3.17.3 from Fedora 21. I got no messages on dmesg or
anything of the sort. I know the btrfs fsck situation is complicated,
but is there any utility I should use to try and repair this? Losing
this file is not a problem, it's just one header from the kernel I was
building.
Regards,
Daniel Miranda
