Well, it's late enough, I'm adding data files to one of my tablespaces, because one of our RAIDs has failed, so I shall not mince my words. Emperor has no clothes. Linux is a toy OS for toy boxes. Linux has huge problems with things like async I/O and direct I/O which are easily available on any serious OS. I would also advise against using very large databases on a Linux system - one should use HP-UX or AIX instead. Those operating systems are stable, well-supported and battle tested Unix systems which have a proven track record of performing heavy duty work on large boxes. Linux has proven track record of causing problems and being a good platform for playing Wolfenstein and BattleZone. Using Linux for very large databases is the same thing as using Windows for very large databases: it means living dangerously. Being a conservative creature, I don't like the idea. If you are into fault-tolerant BattleZone game, Linux is ideal for you.
