installation of linux: should i go with the new default BTRFS file system?!


Recommended Posts

hello and good day dear Linux-experts,

i want to install a new opensuse linux on a notebook. i want to upgrade is the following:

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

what is wanted:
i want to do a total fresh installation
i want to have not tooo much partitions!
i only want to run opensuse 13.2
i want to have some kind of native linux partitions - such as ext 4 - #

what do you suggest - should go with the new default BTRFS file system?!?

well to begin with the beginning: i applied the following commands

a. lsblk

b. fdisk -l

see the results,,,, ;


linux-c5sz:/home/martin # lsblk
sda 8:0 0 465,8G 0 disk
├─sda1 8:1 0 4G 0 part [sWAP]
├─sda2 8:2 0 102M 0 part
├─sda4 8:4 0 1K 0 part
├─sda5 8:5 0 2G 0 part
├─sda6 8:6 0 4G 0 part
├─sda7 8:7 0 10G 0 part
├─sda8 8:8 0 20G 0 part /
└─sda9 8:9 0 389,6G 0 part /home
sr0 11:0 1 1024M 0 rom

and the following fdisk -l


linux-c5sz:/home/martin # fdisk -l

Disk /dev/sda: 500.1 GB, 500107862016 bytes, 976773168 sectors

/dev/sda9 159768576 976766975 408499200 83 Linux
linux-c5sz:/home/martin #

subsequently the questions; which partition logic should i choose.

what is wanted: i want to have not tooo much partitions!
i only want to run opensuse 13.2

note: i want to erase all the existing partition logic /(that is currently existing)
i do this with Gparted.

which partitions should i take?
which file system ?

i am curious to get to know your ideas

hello dear Jazzman




many many thanks for the reply. your answer is very very helpful.


to answer your questions:


i only want to use one operating system

i am not sure about the BTRFS question


some of my friends recommend it as it should be cool for the root partition and because it supports snapshots



well i am not sure about the usage of BTRFS - would  you recomment it!?




well one question tough


one question regarding the preparing of an upgrade.

today i want to ask a linux-question: i am preparing a upgrade from opensuse 13.1 to 13.2

and i want to do a fresh installation.

first of all - as a preliminary task i will do a saving of all the files - that are in the home of the current installation

what else shoud i safe - more than the /home/my_name


should i save anyting else ...


General overview of the Linux file system

Table 3-2. Subdirectories of the root directory
Directory    Content
/bin    Common programs, shared by the system, the system administrator and the users.
/boot    The startup files and the kernel, vmlinuz. In some recent distributions also grub data. Grub is the GRand Unified Boot loader and is an attempt to get rid of the many different boot-loaders we know today.
/dev    Contains references to all the CPU peripheral hardware, which are represented as files with special properties.
/etc    Most important system configuration files are in /etc, this directory contains data similar to those in the Control Panel in Windows
/home    Home directories of the common users.
/initrd    (on some distributions) Information for booting. Do not remove!
/lib    Library files, includes files for all kinds of programs needed by the system and the users.
/lost+found    Every partition has a lost+found in its upper directory. Files that were saved during failures are here.
/misc    For miscellaneous purposes.
/mnt    Standard mount point for external file systems, e.g. a CD-ROM or a digital camera.
/net    Standard mount point for entire remote file systems
/opt    Typically contains extra and third party software.
/proc    A virtual file system containing information about system resources. More information about the meaning of the files in proc is obtained by entering the command man proc in a terminal window. The file proc.txt discusses the virtual file system in detail.
/root    The administrative user's home directory. Mind the difference between /, the root directory and /root, the home directory of the root user.
/sbin    Programs for use by the system and the system administrator.
/tmp    Temporary space for use by the system, cleaned upon reboot, so don't use this for saving any work!
/usr    Programs, libraries, documentation etc. for all user-related programs.
/var    Storage for all variable files and temporary files created by users, such as log files, the mail queue, the print spooler area, space for temporary storage of files downloaded from the Internet, or to keep an image of a CD before burning it.

well - reagarding the thunderbird and other things more.
note:  i have thunderbird and enigmail up and running.

so i need to save
a. the passwords
b. the mails.

question: is there a need to save more than the home/my_name ?!

love to hear from you

You don't have to backUp all the /home directory, but only -> your documents, music, vidoes, pictures and thunderbird (mozilla) directory.  If you have a data (websites) in /var/www apache home dir, you should backUp it as well.



i only want to use one operating system

Then, approximately, 13 - 15GB for root, 2 - 3GB for swap and the rest for /home.



i am not sure about the BTRFS question

BTRFS is a new file system, use ext4 instead.
