Single ext2 filesystem. We still dirty pretty quickly (data collected every 5 seconds). # grep Dirty OUT Dirty: 312 kB Dirty: 1121852 kB Dirty: 2896952 kB Dirty: 4344564 kB Dirty: 5310856 kB Dirty: 5507812 kB Dirty: 5714884 kB Dirty: 5865132 kB Dirty: 6004276 kB Dirty: 6206544 kB Dirty: 6380524 kB Dirty: 6583200 kB Dirty: 6727296 kB Dirty: 6708564 kB Dirty: 6733768 kB Dirty: 6737868 kB Thanks, Badari - 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/
