That is not file system corruption, but something else.

Notice the print-out of 'unknown-block(0,0)', this suggests that the kernel
wasn't able to resolve the device name from a string to a proper [major, minor] 
tuple. cobd is major 117. Perhaps because the passed string was 'cobd/0' instead
of 'cobd0'?
