标题: suse 10 sp2 文件系统管理问题求助
各位专家，请教一个问题，为什么会出现下面第4步时的错误呢，怎么解决呢？非常感谢！

操作系统：suse 10 sp2
目的：/home目录占150G，想腾出120G出来分给/opt

问题详细描述：
1、系统初始划分的空间如下：
linux-oph9:~ # df -m
Filesystem          1M-blocks    Used Available Use% Mounted on
/dev/sda4             65992    1695    64298 3% /
udev                      3988       1    3988 1% /dev
/dev/sda2             153602    33 153569 1% /home
/dev/sda3             61442    489    60954 1% /opt

fdisk 结果如下：
Device Boot    Start       End    Blocks Id  System
/dev/sda1             1       523    4200966 82  Linux swap / Solaris
/dev/sda2          524    20105 157292415 83  Linux
/dev/sda3          20106    27938 62918572+  83  Linux
/dev/sda4 *    27939    36351 67577422+  83  Linux

2、通过fdisk 重新划分后结果如下：（重启系统之后）
Device Boot    Start       End    Blocks Id  System
/dev/sda1             1       523    4200966 82  Linux swap / Solaris
/dev/sda2          524       2815 18410490 83  Linux
/dev/sda3          2816    27938 201800497+  83  Linux
/dev/sda4 *    27939    36351 67577422+  83  Linux

3、linux-oph9:~ # mount /home    （达到了预期的结果）
linux-oph9:~ # df -h
Filesystem          Size  Used Avail Use% Mounted on
/dev/sda4             65G  1.7G 63G 3% /
/dev/sda2             23G 33M 23G 1% /home

4、linux-oph9:~ # mount /opt  （mount出错）
mount: wrong fs type, bad option, bad superblock on /dev/disk/by-id/scsi-3600508e000000000e90ffef927438806-part3,
   missing codepage or other error
   In some cases useful info is found in syslog - try
   dmesg | tail  or so

5、磁盘相关ID信息如下：

这么久了，没有高手出来指点吗？

也许太长，看起来累，那么就简单一点吧，mount 的时候为什么会出现这样的提示呢？

4、linux-oph9:~ # mount /opt  （mount出错）
mount: wrong fs type, bad option, bad superblock on /dev/disk/by-id/scsi-3600508e000000000e90ffef927438806-part3,
   missing codepage or other error
