Hi Eric,
Thanks for the reply. You are correct to some extent though I don't
agree with that completely. For the simple reason that today ext{3,4}
are targetting for being enterprise filesystem and its completely
valid to have the device such bugs. Imagine by the time you realise
that your important data was not properly written to disk and has been
lost , the damage has been already done. So I guess either the
underlying raid software or the file system should have a way of
guaranteeing that the data is safe.
