    Default Separate Drive in root

    While in installation we create partitions. Today i installed 11.2 M3 KDE and create an extended partition with ext3. And mount it as /Backup. By default it will be in root filesystem as a folder.
    So my questions are:
    1- Is it possible to make it a drive like in Ubuntu. i mean that it will be showed in places in left panel of the dolphin. Maybe mount in media or mnt. (OR is this the default style in openSUSE for other partitions?)
    2- The size of the partition(Backup) is 183.1GB, and now is 173.6GB. where is rest of the space gone?, There is even no folder in this partition.

    Thanks.

    Maybe you just express it a bit unprecise, but an extended partition can not be mounted. It can only contain other partitions (numbered from 5 upwards). An
    Code:
    fdisk -l
    (as root) might show us what you mean.

    Just for your information: you can mount a partition where you want it in your directory hierarchy. The normal user will have no idea about this, but just see directories from / downwards and somewhere she/he will cross to another partition, but not know this. Maybe this wiki SDB:Basics of partitions, filesystems, mount points - openSUSEmay be of help getting the picture.

    Thanks for the reply.
    Yeh, i didn't express it well. From extended i mean extended drive holding logical drives.
    In this case i have sda5,sda6,sda7. sda7 is pointing to Backup.
    The 1st question i solved by right clicking in the panel and choose 'add entry'. Maybe openSUSE architecture is different in this case. It just create a folder in / and use it as partition.

    But my 2nd question is still a mystery for me.

    You will probably find that the missing space is required for the journal
    and other "stuff" ( technical term )

    Thanks baskitcaise for clarifying the space question.
    Is it depend on the total space of the partition.
    lets say, i have 50Gb for root with logical term, not primary. How much it can take?
    Every one hold same space in term of size of the partition. I mean primary and extended(logical all).
    Because in 183GB, it at least occupy 10GB for journal.

    The space needed for 'administrative' purposes has nothing to do with the type of partition. It is a property of the file system.

    Part of this 'lost' space is also a reserve of 5% (default). When the fs is 100% full for normal users, root still has access to this 5%, so the system can run and root can repair.
    This 5% can be changed, and when the fs is rather big you could consider to make it lower. I would not recommend to make it 0% on /, but on a data only fs that could be considered. See the man page of tun2fs and the -m option.

    Dang you beat me to it :-)

    And I was doing ever so well there.

    however you put it much more succinctly and readable than I would have in my
    own bumbling round about way.

    Cheers

    I hope that what I write is understandable, but as english is not my mother tongue, you could have done it faster then I, was it not for the hour time difference. Hope it helps the OP.
