上此说到升级了grub2后，grub就能识别由e2fsprogs1.14.12格式化的文件系统（mkfs.ext3 -F /dev/sda1)
现在说哈原因，在mkfs.ext3 -F /dev/sda1后可以通过 tune2fs -l /dev/sda1 查询硬盘的相关信息。我发现其中有一条是这样的
Inode size: 256
但是如果是用 e2fsprogs1.37的话，同样进行查询就会有一下的信息
Inode size: 128
查询了grub的相关资料，知道grub1能识别的文件系统,inode size 就是128的，所以用升级了的e2fsprogs制作的文件系统老版本的grub不认，
man mke2fs（高版本的，发现有一个选项 ）
-I inode-size
Specify the size of each inode in bytes. mke2fs creates 256-byte
inodes by default. In kernels after 2.6.10 and some earlier vendor
kernels it is possible to utilize inodes larger than 128 bytes to
store extended attributes for improved performance. The inode-size
value must be a power of 2 larger or equal to 128. The larger the
inode-size the more space the inode table will consume, and this
reduces the usable space in the filesystem and can also negatively
impact performance. Extended attributes stored in large inodes are
not visible with older kernels, and such filesystems will not be
mountable with 2.4 kernels at all. It is not possible to change
this value after the filesystem is created.
哈哈，就是这个了，现在制作文件系统时，我需要这么作
mkfs.ext3 －I 128 -F /dev/sda1
好了，grub能够正确的识别文件系统了
