The only comment made was something I said about raw devices on Linux. Someone said there is a raw device option for Linux and whether we wanted to try using it. I said most modern filesystems can move data at the speed of the disk, so raw devices really don't buy much. I mentioned that ext2 is not a modern file system. The *BSD filesystems are an example of a modern file system. This may be what Marc is remembering. Unfortunately, this does not relate to the user's question. (Raw devices do have advantages because of read-ahead control and disk flush control. However, we seem to be doing fine without these marginal improvements, and raw devices have a host of complex problems when implemented.) -- Bruce Momjian | http://www.op.net/~candle maillist@candle.pha.pa.us | (610) 853-3000 + If your life is a hard drive, | 830 Blythe Avenue + Christ can be your backup. | Drexel Hill, Pennsylvania 19026
