Hi, OLPC has started using ext4 online resizing to grow our filesystems to use the whole SD card on first boot - something we never did before. Working very nicely, thanks! I'm trying to simplify/improve the scripts involved in doing this. How can I programatically check if an ext4 fs already fills its partition, or if it has room to grow? The numbers produced by dumpe2fs (e.g. block count) or "df" don't seem to exactly line up with the sizes produced by fdisk. One easy solution, if possible, would be to find out the number of the last sector used by the filesystem. I could then very easily compare this to the "end" information found in sysfs for the partition. Then I can make the decision on whether to grow or not.
