Btrfs devel - Apr 2013 - Logical/i-nodes lookups give "path resolving failed with ret=-2"

Hi,


I scrubbed a BTRFS volume (mounted as a VFS root) and got several
errors. However I am not able to make btrfs print the path of the
corrupted files...

E.g. kernel log gives :


[51078.682876] btrfs: unable to fixup (regular) error at logical
51241746432 on dev /dev/root
[51078.683013] btrfs: checksum error at logical 51242385408 on dev
/dev/root, sector 102196320, root 684, inode 60676040, offset
352583680: path resolving failed with ret=-2
[51078.683016] btrfs: bdev /dev/root errs: wr 0, rd 0, flush 0,
corrupt 35782, gen 0

Manual lookup  :

# btrfs  inspect-internal logical-resolve -v  51241746432 /
ioctl ret=0, bytes_left=4080, bytes_missing=0, cnt=0, missed=0
# ./btrfs  inspect-internal inode-resolve 60676040 /
ioctl ret=-1, error: No such file or directory

Kernel is Linux 3.9-rc8, latest btrfs-progs from Chris Mason''s Git
repository.

I am sure I am missing something but I am unable to figure out
what.... Any idea? Thanks!!

Adrien

Maybe: find / -xdev -inum 60676040
