But Peter does NOT say that. > ext3 journals are much safer on mirrored devices than on non-mirrored That's irrelevant - you don't care what's in the journal, because if your system crashes before committal you WANT the data in the journal to be lost, rolled back, whatever, and you don't want your machine to have acked the write until it actually has gone to disk. Or at least that's what *I* want. But then everyone has different wants and needs. What is obvious, however, are the issues involved.
