When mkfs.ext4dev with flex_bg option, resize2fs with -M option will fail. While calculate how many blocks need to move, the result is wrong. Because some block groups have no meta_data if mkfs.ext4dev with flex_bg option, all meta_data are stored in the flex group. Steps to reproduce: # mkfs.ext4dev -O flex_bg /dev/sda6 # resize2fs /dev/sda6 -M resize2fs: No space left on device while trying to resize /dev/sda6 -- To unsubscribe from this list: send the line "unsubscribe linux-ext4" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
