Which kernel did you use for testing? If you use the latest -mm kernel (2.6.27-rc5-mm1) with a patch at http://userweb.kernel.org/~akpm/mmotm/ broken-out/jbd-test-bh_write_eio-to-detect-errors-on-metadata-buffers.patch, most of this kind of problems may be solved. But some additional works are still needed; nobody checks I/O error on updating a journal super block. > Anyway, I would be very happy to test out any patches in this area, and > if none exist, I will try to track down why it is ignoring some of these > errors.
