For one, you could've used fstat -f / to reduce the noise. Secondly, since 
rebooting does not help, open files are not the cause. Rather the VBAD up 
there. Do an fsck -y. Chances are your file system got filled, a hardware 
write error occurred and the kernel could therefore not return the space to 
the disk.
If you still have logs, I would grep for WRITE_DMA in /var/log/messages.
