关于mount系统的问题.

sql2000

我原来mount的NFS系统是只读的,我将配置文件/etc/fstab修改为可写.
怎么不重新启动机器,使它生效呢?

我umount它时是busy, 可以强制umount 吗?

fuser看一下进程号，如果不是关键进程杀掉算了，umount，改完了再重新mount上。应该是不用重起就能生效。

在HP-UX下面,我不可以强制卸载吗?
我用umount发现没有 -f的选项,跟solaris不同呀.

Hi,
You don\'t have to \"umount\" the file system. Use the \"remount\" option.
e.g.

# mount -F vxfs -o remount,rw /mount-point

Hope this helps.

Hi, again:

I may have given you wrong advice. When you change a file system to \"read only\" to \"read write\", the above command will tell you that the file system is corrupted and force you to do fsck. Only when you change the mounted file system from \"rw\" to \"ro\", the above command will succeed.

So, in your case, you may have to do:
1) vi /etc/fstab to make the file system read, write (or just use \"default\".
2) fuser -ku /mount-point
3) umount /mount-point
4) mount /mount-point

Good Luck.
