Btrfs devel - Jun 2010 - Music-files suddenly not recognized anymore, empty files - Btrfschk reports errors

Hi,

Recently Amarok started to reject some of music files.
Some files seem to be simply corrupted (mplayer is still able to play
them), other have zero length.

Btrfsck reports:
root 5 inode 1371 errors 400
found 42498768896 bytes used err is 1
total csum bytes: 41015664
total tree bytes: 498728960
total fs tree bytes: 406466560
btree space waste bytes: 110792472
file data blocks allocated: 271306133504
 referenced 46886879232
Btrfs Btrfs v0.19


Anything I can do to repair those errors?

Thank you in advance, Clemens

No snapshots unfourtunatly.

I wonder what could have caused those filesystem errors.
The only "unusual" thing I did was to mount it with
"compress", but
other than that - i didn''t even stress it a lot.

Oh, sad to hear that. Ok I guess that means backing up my data and
re-formating is probably the best I can do.

Thanks, Clemens

These errors are non-fatal, which kernel are you running?  Do you have
any btrfs related kernel messages?

Did the system crash at all?
