    linux-installation: which partition-logic should i use - which size?


    hello and good day,


    i an planning to move from OpenSuse version 13.1 to 13.2 in the next days:

    note: i am planning to do so for two notebooks:

    for this note book- that is mentioend above:
    Samsung q 210, 12,1" OpenSuse 13.1: Intel® Core™ 2 Duo Proz. P8400 2,26 GHz 1066 MHz FSB 3 MB with a 250 GB - HDD
    note: i ve got another notebook that needs to get upgrade too: this one: Akoya P 6512 15" OpenSuse 13.1: AMD Athlon X2 P320, 2,10 GHz, 4 GB with a 320 GB hdd-drive. but this one will be discussed in another thread.




    to beginn with the Samsung-notebook - Samsung q 210, 12,1" Intel® Core™ 2 Duo Proz. P8400 2,26 GHz 1066 MHz FSB 3 MB with a 250 GB - HDD - currently opensuse 13 . 1 on -

    i want to do a fresh install!!! see the following commands that give back the conditions of the machine and the drive...as it is at the moment.


    linux-70ce:/home/martin # fdisk -l

    see the following values and insights into the technical data of the samsung-notebook:

    lsblk

    some ideas regarding the Samsung q 210

    i have a DOS/MBR partitioned disk.
    Why only one Primary(Extended) partition covering the whole drive, and the rest Logical partitions?
    i can have 4 Primaries: It makes more sense to have 3 Primary partitions and make the 4th an Extended
    for additional partitions, all of those (in the 4th Extended) as Logical partitions.
    well that are a very important things: i want to get rid of the DOS/MBR partitioned disk. Therefore i want to use GParted (see also below)
    some ideas about the partioning . . to begin with the tools: like the idea of layouting with GParted


    and i like the idea of using ext4 partitions.


    Of course i will use custom partitioning, I will Create New Partition Table, I will choose MSDOS instead of GPT for the type of partition table.
    The situation with the Samsung 210 notebook at the moment:

    linux-70ce:/home # fdisk -l
    Disk /dev/sda: 320.1 GB, 320072933376 bytes, 625142448 sectors

    Sector size (logical/physical): 512 bytes / 512 bytes
    I/O size (minimum/optimal): 512 bytes / 512 bytes

    Disk identifier: 0xdf16504f

    i am a big fan of GParted - and for sure i want to use it:

    hmmm: I plan to create a 20-G root (/) partition (Primary),
    a Swap partition twice the size of my installed RAM (Primary, again),and
    an 80-G /home partition (Primary, again).


    Well; the idea of creating the partions with Gparted.

    Which are the appropiatd values of partioning for this note book:
    Samsunng q 210, 12,1" OpenSuse 13.1: Intel® Core™ 2 Duo Proz. P8400 2,26 GHz 1066 MHz FSB 3 MB

    note: i ve got another notebook that needs to get upgrade too:

    this one: Akoya P 6512 15" OpenSuse 13.1: AMD Athlon X2 P320, 2,10 GHz, 4 GB 320 GB hdd-drive

    what would you suggest for the Akoya-Notebook: which values for the partition?

    look forward to hear from you
    many greetings

    With storage being relatively cheap, I'd take out the working drive and insert a new SSD or SATA drive perhaps one that draws less power.
    That way if I break anything I can just swap the drives out.

    However, for some notebooks it is really difficult to get the drive out. An old Samsung notebook of mine had 24 screws to remove.

    I can't recommend ideal partition sizes, as I like to try out many different distributions, but I use 20GB as a default.

    To upgrade from 13.1 to 13.2 why do you want to do a fresh install? The YAST package manger should be able to do a clean upgrade in-situ without a lot of weeping and gnashing of teeth.
    Sometimes, real fast is almost as good as real time.
    Just remember, Semper Gumbi - always be flexible!

    hello dear rubberman

    many many thanks for the reply - i did it: i runned the installation of opensuse 13.2
    well i am not an expert see the results of the partition....
    note there were many mnay partitions on the harddrive ...

    now i have a few less that that many

    how do you think about the patition logic?

    btw: have found some issues with the network configuration---..

    i allways struggle with ifup and knetowkrmanager .... At the moment i only can run the notebook with the ethernet wire connected. No wlan is possible

    what can i do now;

    see some issues that i found out!


    !!! CND0120E: the Netzwerkinterface wlp4s0 has got no IP Adress
    !!! CND0290E: no networkconfiguration for Interface wlp4s0 found
    !!! CND0490E: no Accesspoint with the SSID on the Interface wlp4s0 found
    !!! CND0380E: no WLANs at Interface wlp4s0 found. the hardware and drivers are not well configured
    what do you suggest
