setting up & optimizing the partition table on a Notebook that will run OpenSuse Leap 42.1

hello dear OpenSuseLinux-experts,
c see the signature - i have freshly installed OpenSuse Leap42.1

how to check the partition-table - and how to optimize it: We could start with getting:

the technical data of the notebook:
Display: 15.6" solution: 1366 x 768 ( WXGA )
cpu AMD Athlon II X2 P320 /2.1 GHz
Grafic: ATI Mobility Radeon HD 5470
HDD 500 GB RAM: 4 GB
the notebook was sold with: Microsoft Windows 7 Home Premium 32-Bit, Microsoft Windows 7 Home Premium 64-Bit

but i never ever used it - you will see that the hdd is partitioned accordingly.

so i guess that i can optimize all a bit …

what would you do to optimize …!?

It all depends on what you wish to use the machine for. A desktop is going to be different then a server and different types of servers may have different partitions. There is no one right way.

Also it may depend on the sizes and types and numbers of drives. You show a MSDOS style partitioning and GPT style is going to be different. So it depends…:open_mouth:

hi i do not need the MSDOS-thnigs any more.
Perhaps we can clean up the harddrive a bit - and yes i do not need the number of drives

On a system with only a 500GB disk, if you intend to use this machine for many different things (your workhorse), I’d re-install with the following changes from the default

Disk layout

  • Uncheck the box that sets up a separate /home partition. Over the long run, you can’t afford the inefficiency of having too much free space either in the root or home partitions.
  • Consider whether you want to use BTRFS. It has the ability to easily and automatically create snapshots to recover. But, EXT4 also has your choice of a couple utilities where you can create snapshots and easily recover as well… You just need to install and configure because they aren’t installed by default.
  • Consider a “light” alternative to the default KDE or Gnome when you “only” have 4GB RAM which I consider minimal for a practical experience. If you’ve used openSUSE KDE before, I recommend installing LXDE. If you’ve used openSUSE Gnome before, I’d recommend XFCE. Each “light” alternative will give you a full Desktop experience but without all the automation and graphical toys you’ll find in KDE or Gnome.

IMO,
TSU

I admire “easily” in this case.

You just need to install and configure because they aren’t installed by default.

Are those utilities classified so you do not even name them? Why you mention them in the first place then?

I do agree with some of what you are saying, like EXT4 instead of BTRFS and maybe a light DE instead of a heavy one, although KDE5 feels snappy compared to KDE4. Looking at the hardware of the laptop I think it is enough to use KDE5.

What I absolutely don’t agree with you is the fact you write to NOT have a separate /home partition. I always have one and I am happy with it. Have it for years and with every change in OS I keep it, never have to restore my data after backing it up because of (re-)installing an OS.

Make a 40GB / partition, a 5GB swap partition and use the rest for /home. You will have plenty of space unless you are a fanatic downloader who will have his disk full in no time. But then you should have bought a different computer in the first place.
Why 5GB for swap? When you use hibernation the complete contents of memory will be stored to the swap space on disk. Therefore it has to be equal to or larger than your memory size. And oh yeah, remember to use the 64 bits version of which ever OS you are going to use, so you can use the 4GB of RAM completely. With a 32bit system you only have around 3.5GB.
Success and have fun.

hello arvidjaar hello dear JanMussche

many many thanks for the answers -and all the hints.

Great to hear from you. At the moment i know - all windows things should be wiped - i do not want to have any windows-things left…

many thanks Jan Mussche:

i will create a 40GB / partition, a 5GB swap partition and use the rest for /home.

i want to create a Partitionsscheme only for Linux.
i do not want to install windows any more - i want to install opensuse 13.2 (others do not run propperly on the machine)

which partition sheme would you create:


 /dev/sda, Load MBR with Grub
1. /dev/sda1, Primary SWAP (4 GB)
2. /dev/sda2, Primary EXT4 "/" openSUSE Partition zum booten (36-60 GB)
3. /dev/sda3, Primary EXT4 "/home" das home directory (Rest of the hard disk)

note: i want to wipe all windows things - How to do that with GPARTED

would love to hear from you

well - do you think that i will ned to have an EFI partition of something like 200Mb, so the system can boot.

that means that this will remain on the hdd. - okay i will leave that on the hdd. The rest can be wiped?!

**BTW **- is there any good **manual or tutorial **(or even book) on all that stuff - creating a partition-sheme. I would love to get it!

can anybody reccomend a good online-tutorial or manual on the topic patitioning sheme /&table. Please advice.

many many thanks

It is a good idea to make full backup of Windows and the efi partition, just in case.

i will read through it all. well i can do some thing like this…

**example one **- a bit sophisticated one:


~> lsblk
NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT
sda 8:0 0 465,8G 0 disk
├─sda1 8:1 0 156M 0 part /boot/efi
├─sda2 8:2 0 400M 0 part /boot
└─sda3 8:3 0 465,2G 0 part
└─cr_ata-ST500LT012-xxx_xxx-part3 254:0 0 465,2G 0 crypt
├─system-swap 254:1 0 2G 0 lvm [SWAP]
├─system-root 254:2 0 40G 0 lvm /
└─system-home 254:3 0 423,2G 0 lvm /home

this i cannot be created with gparted


└─cr_ata-ST500LT012-xxx_xxx-part3 254:0 0 465,2G 0 crypt
├─system-swap 254:1 0 2G 0 lvm [SWAP]
├─system-root 254:2 0 40G 0 lvm /
└─system-home 254:3 0 423,2G 0 lvm /hom

but this line looks interesting. …

└─cr_ata-ST500LT012-xxx_xxx-part3 254:0 0 465,2G 0 crypt

unfortunatley: Currently GParted supports operations such as creating, resizing, and deleting LVM Physical Volumes (PV) see the GParted Features. However it does not yet support operations on LVM Logical Volumes (LV). As such we will need to use other tools, such as lvm from the command line to work with LVs.

but - as mentioned above this is a sophisticated one. a easier one is this.


 /dev/sda, Load MBR with Grub
1. /dev/sda1, Primary SWAP (4 GB)
2. /dev/sda2, Primary EXT4 "/" openSUSE Partition zum booten (36-60 GB)
3. /dev/sda3, Primary EXT4 "/home" das home directory (Rest of the hard disk)

this second one does not use LVM and is easier to create :wink:

well the easier thing is to run this partition-sheme


 /dev/sda, Load MBR with Grub
1. /dev/sda1, Primary SWAP (4 GB)
2. /dev/sda2, Primary EXT4 "/" openSUSE Partition zum booten (36-60 GB)
3. /dev/sda3, Primary EXT4 "/home" das home directory (Rest of the hard disk)

and yes:

with GRUB we can go ahead - installing a first Linux and then having the option to install a second too.
so i first of all need to do one thing. Install opensuse 13.2 first

**but the question of the day **is: what to do with the old EFI partition on the Notebook -can this be wiped or not…

in other words - what do i need to do with the following lines:


Device         Start       End   Sectors   Size Type
/dev/sda1       2048   1050623   1048576   512M EFI System
/dev/sda2    1050624  84951039  83900416    40G Microsoft basic data

If you go to MBR only boot then there is no need for a EFI boot. It is used only when you boot in EFI mode.

hello dear glgalthorp,

many many thanks for the quick answer:

regarding the EFI-Partition on the HDD _ see the following hints:

this one is very good: http://askubuntu.com/questions/682147/can-i-erase-all-partitions-including-efi-and-install-only-ubuntu

**question: **Can I erase all partitions including EFI and install only Ubuntu?

**Answer 1 **
Yes, when you completely erase the disk, you can install ubuntu as the single operating system.
When you can disable UEFI in BIOS (mostly you can) you even can install ubuntu in mbr mode.
Boot from ubuntu install media, open GParted and create a new partition table - choose mbr.
In case you can not disable UEFI and/or secure boot you as well can install ubuntu in EFI mode.
Then the installer will create a new EFI partition where the GRUB boot loader will be installed.

**Answer 2 **
You question is not completely clear to me. If you want to install Ubuntu in UEFI mode here is what you need to do :
You will need to set your BIOS in UEFI mode and to create an UEFI bootable Ubuntu USB key.
Follow this guide to create a UEFI bootable USB. Then simply run the Ubuntu installer;
at step Installation Type, select Something Else and partition your disk as explained in this answer.
If boot mode (UEFI or Legacy) does not matter for you simply install Ubuntu as usual. (Refer to this guide if needed)

**Answer 3 **
You need to keep UEFI mode only if you want to install Ubuntu in UEFI mode. –

answer 4
The question uses some terminology incorrectly, which can lead to confusion and problems down the road, so I want to address these issues first.
The Extensible Firmware Interface (EFI), or its 2.x version, the Unified EFI (UEFI), is a type of firmware. The EFI is not a partition. That said, there is a partition called the EFI System Partition (ESP), which holds boot loaders. Chances are that lapisdecor meant “ESP” rather than “EFI” in the original question.
Also, the EFI is a type of firmware that replaces the older Basic Input/Output System (BIOS). As such, if your computer uses an EFI, it does not have a BIOS. There are, however, some caveats and exceptions. Most commonly, EFIs provide a feature called the Compatibility Support Module (CSM), which is a sort of BIOS emulator; the CSM is to EFI like what dosemu is to Linux, in that it enables a newer and more sophisticated environment (EFI or Linux) to run programs designed for an older and simpler system (BIOS or DOS). In other words, “BIOS” in the original question should be “EFI.” That said, using “BIOS” in place of “EFI” is a common practice. It’s a bad one, but it’s common, both among users and among manufacturers. I suspect it’s done because people know (more or less) what a BIOS is, whereas “EFI” is an unfamiliar acronym; and since EFI replaces BIOS, using “BIOS” makes the job easier for copywriters. The trouble is that people then drag all their BIOS knowledge up when they read “BIOS,” but much of it is inapplicable. EFI boots in a very different way from BIOS, so if you think of EFI as being an enhanced BIOS, you’ll have a mental model that’s very wrong and you’ll make mistakes. Then people like me end up spending a lot of time explaining how it all actually works – but I digress…
Moving on to real issues: If you’re “in legacy mode,” that just means that your CSM is active. This does not guarantee a boot in BIOS/CSM/legacy mode, though. On most EFI-based computers, when the CSM is disabled, the boot path is relatively simple; you can boot only EFI-mode boot loaders. Note that you can’t “disable the EFI”; the EFI is the firmware, and it’s in charge of the computer. Some computers do enable you to disable the ability to boot in EFI mode, but such options are rare – and some computers provide interfaces that make it sound as if you’re disabling EFI-mode booting, but you really aren’t. When you activate the CSM, most computers enable either type of boot loader to run, which makes it impossible to predict what will happen when you feed the computer a disk that provides both types of boot loader. This isn’t normally a big deal for a single-boot computer; when you install the OS, the installer will detect its boot mode and install the boot loader only for the installer’s boot mode, so the computer can boot from the hard disk only in that same mode. If you multi-boot, though, you can easily install one OS in one boot mode and the other OS in the other boot mode. The hair-pulling begins at this point.
In the not-too-distant past, EFI-mode booting was an exercise in frustration because of bugs in EFIs, bugs in boot loaders, and misinformation, which often made enabling the CSM appealing. Today, though, EFI-mode booting poses fewer problems, and my estimate from questions posted here and elsewhere is that the biggest single problem area today is from activated CSMs. Thus, I recommend that the CSM (aka “legacy boot”) be disabled on EFI-based computers unless you have a good reason to enable it. To be sure, EFI-mode booting today poses more challenges than BIOS-mode booting did five years ago; but on an EFI-based computer, BIOS-mode booting creates pitfalls that didn’t exist five years ago.
So, that long-winded stuff out of the way, let’s get back to your original question, re-phrased slightly:
Can I erase all partitions on my computer, including ESP, and install only Ubuntu? Will the EFI work in this case?

Yes and yes.

After you erase your partitions, the Ubuntu installer will create new ones if you select an automatic partitioning option. If you partition manually, you’ll need to create appropriate partitions. These may include an ESP if you install in EFI mode or a BIOS Boot Partition if you install to a GPT disk in BIOS mode.

again - dear glgalthorp, many thanks for your answer!

  • this is very helpful!

My personal favorite which has worked flawlessly for me is this
http://extundelete.sourceforge.net/

Not in the OSS, but I highly recommend.
Simple to use.
Set it and you can forget it, like BTRFS’ Snapper it’ll run in the background. Run a couple tests when you first start up (delete something and recover it), then it’ll just be there to save your bacon if you ever need it.

Note that this is a tool which must be installed <before> you need it, there are other “undelete” tools which can also recover files even if it wasn’t installed before you found you needed to recover a file. Of course, a recovery app installed <after> you want to recover risks over-writing critical data on the disk unless you mount the disk on another system.

hello dear comunity, hello dear Tsu

first of all many many thanks for the answer - great to see this community alive - you are very very supportive.

the notebook; HP Notebook hp 14 r 103ng - 500 GB HDD, intel pentium n 3450 a 2.16 ghz
and this processor is supposed to make teribble errors

the system is also called bay trail -

now i have had to install opensuse 13.2 on this notebook - since this notebook is affected by a very very serious bug -

just installed tumbleweed with kernel 4.4.2.1 on this new HP Notebook - see the signature.
But i recognized that the shutdown-process does not work at all. The notebook does not shut down properly. In other words - i cannot turn off the sytem …
it freezes all.

by the way; this also happened with

  • openSuse Leap 42.1
  • ubuntu version 15.10

funny: only **with OpenSuse 13.2 it **worked well?!

see more on this topic here -in this thread: https://forums.opensuse.org/showthread.php/514101-leap-42-1-and-tumbleweed-shutdown-amp-turn-off-does-not-work-at-all-freezing-100

so i finally have installed opensuse 13.2 - see the arrangement of the partition -

note: i will try out other installations - in order to find out - if i am able to run other installations too.
Goal: opensuse 13.2 is the main installation - and others should be tested.

Question - is this possible with the following arrangement!?
