Hence wanting documentation properly explaining the situation, yes. Often the people writing the documentation aren't the people who know the most about the situation, but the people who found out they NEED said documentation, and post errors until they get sufficient corrections. In which case "you're wrong, it's actually _this_" is helpful, and "you're wrong, go away and stop bothering us grown-ups" isn't. > Metadata takes up such a small part of the disk that fscking > it and finding it to be OK is absolutely no guarantee that > the data on the filesystem has not been horribly mangled. > > Personally, what I care about is my data. > > The metadata is just a way to get to my data, while the data > is actually important. Are you saying ext3 should default to journal=data then? It seems that the default journaling only handles the metadata, and people seem to think that journaled filesystems exist for a reason. There seems to be a lot of "the guarantees you think a journal provides aren't worth anything, so the fact there are circumstances under which it doesn't provide them isn't worth telling anybody about" in this thread. So we shouldn't bother journaled filesystems? I'm not sure what the intended argument is here... I have no clue what the finished documentation on this issue should look like either. But I want to read it. Rob -- Latency is more important than throughput.
