Not necessarily; it just means that 32% of your files have at least one discontinuity. Given the ext3 layout, by definition every 128 megs there will be a discontinuity because of the metadata at the beginning of every single block group. You have a small number of files on your system (349) occupying an average of 348 megabytes. So it's not at all surprising that the contiguous percentage is 32%. The recent Flex BG feature that was recently pulled into 2.6.23-git14 for ext4 is desgined to avoid this issue, but a seek every 128 megs is for most workloads not a big deal and will hopefully not cause you any problems. - Ted - To unsubscribe from this list: send the line "unsubscribe linux-fsdevel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
