the bitmap has performance implications... for example: http://www.mail-archive.com/linux-raid@vger.kernel.org/msg07229.html i still prefer to use the bitmap -- i just make it external for devices which are busy. note that unless you tweak your init scripts you'll need to put external bitmaps on your root partition, see this thread: http://www.mail-archive.com/linux-raid@vger.kernel.org/msg06441.html -dean - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
