Thread: Partition manager not mounting extra / partition

  1. #1

    Default Partition manager not mounting extra / partition

    Hi

    The default partition manager which OpenSUSE DVD 11.4 uses (Expert Partitioner) is not creating any logic partition with / mount because another system is already using it, is there anyway to fix this?

    I'm not sure that I understand the question.

    You cannot mount two different partitions as "/".

    If you want to change the partition setup, and there is already a partition assigned to "/", then either delete that partition or change where it will be mounted or set it to not mount, before setting "/" as the mount point for the partition you are trying to change.

    Hi

    If you have already a / partition for another system mounted and trying to create another one for / it prompts an error saying there's already a / partition.

    Obviously. So? I don't see the problem.

    If you have already a / partition for another system mounted and trying to create another one for / it prompts an error saying there's already a / partition.
    When you install openSUSE, only one partition can be assigned as the root or "/" partition. This is where openSUSE will install all of the system files. If you have a previous install of openSUSE, which you want to keep and do not wish to over write, then select a different mount point such as /OS113/Root for instance. If it is your intent to write over an existing openSUSE installation, make sure to select Format The Partition. In all cases, you can have only one partition mounted using the same folder location in the unified Linux file system.

    I interpret your question as: you want access to another system's root partition. To do this, you must (as root) create a mount point (a folder) on your "real" root partition:

    Code:
    mkdir /otherroot
    And then mount the "other" root folder (use "fdisk -l" to figure out where the other root folder is located):

    Code:
    mount /dev/sda[X] /otherroot
    Where [X] is the number of the partition (from fdisk -l), if you have more than one drive, it could also be on sdb instead.

    Please be aware that writing back to this partition is general NOT safe - you could do some damage there.

    I'm sorry, but I wasn't enough clear about my question.

    I've already another system installed with a / mount partition of its own. Trying to install OpenSUSE in the same harddrive (sda) prompts an error because "Expert Partitioner" isn't able to create another partition with / mount point, which is wierd because any other system I've installed works fine.

    I am not sure that you understand how mountpoints work. The mountpoints that you define hold true for your running system only. Read, if you boot from a live system you have different mountpoints for your partitions, than if you run your system installed on HD.

    You cannot boot from a live CD, or so, and then mount your HD partition which holds your linux install as /, because the live CD is already mounted there. Furthermore, all mountpoints that you set with the YaST Partitioner when your are booted from a live system will hold for this live-system only, means your HD install will not know anything about it.


    This is of course different during an install, where the mountpoints that you define are written to the /etc/fstab on the HD that you install to.

    You didn't understood what I meant.

    I'm not trying to set up different mountpoints for live cds but during an install. I've tried to create an extended partition during the install and creating logical partitions, one of them set to mount at / for this install but it doesn't work because it says there's another partition (sda1) with a / mountpoint.

    But where did you want sda1 to be mounted? As long as it is not at "/", then just edit the partition setup for sda1 first and change the mounting before you try to set the logical partition to mount at "/".
