    Angry Unable to umount a partition

    I created a partition with some EASUES Partition maneger from windows of the remaining space i had. Shortly after i ran into boot failiure Grub error 17....
    I corrected it usin the openSUSE cd. When i did an auto repair it checked my fstab and detected my new partition

    /dev/sda8
    it created some mount point in some folder created called data6 in the root.

    When i now booted it /dev/sda8 is mounted to / while my actual linux partition is /dev/sda13.... I can't unmount it format or edit. WHat should i do...
    The problem is that the fstab actually points sda8 to mount it somewhere else. here is my fstab...

    /dev/disk/by-id/scsi-SATA_ST3160215AS_6RA3XAHN-part13 / ext3 acl,user_xattr 1 1

    Default Re: Unable to umount a partition

    This has not much to do with your fstab. / is mounted much earlier in the boot process. Just think of the fact that /etc/fstab can only be read by the system when / is mounted allready. So you can not repair this by changing something in the fstab.

    Also you can not umount a partition that is in use and of course the / partition is always in use on a running system.

    I wonder which system is running at the moment? Beacuse you have something running when you state that you can not umount ...

    I should also look in /boot/grub/menu.lst because there is a root= parameter that tells the boot ystem where the / partition is. You may post the contents here to get more help.
