Music-files suddenly not recognized anymore, empty files - Btrfschk reports errors

Music-files suddenly not recognized anymore, empty files - Btrfschk reports errors

[Clemens Eisserer]

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?
