    Default Problems Partitioning

    I am in the middle of an openSUSE v. 13.1 64 bit Gnome Net Install on a Lenovo ThinkPad W520 with 2 hard drives with 3 other OS's already installed. I created a 50 Gb Btrfs partition on disk sda (sda10) for / and another 50 Gb Ext.4 partition on sda11 for /home.

    openSUSE had proposed a different scheme on sdb7 which I deleted. The problem is, the installation wants to install a /home subvolume on sda10, in spite of my having edited the proposal to read /home on sda11.

    I could delete sda11, enlarge sda10 and let it go ahead, but I'd rather that the installation would recognize the partitioning setup I established during the first part of the oSUSE installation program (now stalled. I dimmed the screen and am going to wait a bit, hoping some oSUSE installation guru can help point the way to a solution).

    I decided to install oSUSE to the laptop after observing that the oSUSE Live DVD had no trouble connecting to the DSL WiFi connection, and rebooted to do the Net Installation.

    I only use 1 of the other three systems, which must be connected through the ethernet port (a wired connection).

    TIA

    I did the following:

    I deleted the /home subvolume from sda10, changed sda11 to brtfs and added a /home subvolume there. I had to do it twice but it finally registered.

    Now I have a different problem. The installation wants to put the boot loader on the MBR of sdb because that's the disk that boots first according to the BIOS configuration. That is reasonable but is not what I want. I have lojack installed and want the laptop to boot automatically into Windows so the lojack will be activated in case it the computer is stolen.

    I'll have to look for a way to change that before proceeding.

    I changed the order of the disks and now it will boot from sda. (I may have to change it back again after installation, if the installation affects the BIOS settings. I boot using a supergrub2 boot disk, since the boot order is usb flash drive, dvd drive, sdb, then sda).

    However - the installation failed. It didn't like the partitions I created using gparted on the v 13.1 Live DVD and couldn't create the subvolumes or use the /home partition.

    A lot of time was wasted. The zypper dup upgrade installation went well on the desktop machine but the laptop installation is going to be more complicated. I'll figure something out.

    Maybe you should show us your partitions. ie give output of fdisk -l

    Your system is complex and I for one don't understand it. So give use some facts

    Just delete the proposal and create your own, or edit the proposal.

    Partition table entries are not in disk order

    My intention was to use brtfs for / and have home on a separate ext.4 partition. Data is kept on a third partition, so I can use the same data with various operating systems. (I began doing that in 1994).

    Downloading the six sections of the net install is time consuming. I may try again using the Live DVD that I already burned. I was able to get the wireless connection working on the other distro installed on the w520 and had trouble logging into the forum from there.

    The partitions are out of order so it is hard to tell and you did not use code tags so the formatting is lost.

    Just junk the recommended and make your own scheme.

    Personally I don't recommend btrfs and you need to be aware that you need to double the estimated size for a partition because it has snapshot feature on by default. But it is fine if you want to experiment.

    In any case mounting a partition at /home should replace any that the btrfs manager thinks it wants or event creates. It would essential be just a mount point

    .
    I have used open SUSE off and on since 2008 and began using btrfs when it was first offered. On the the desktop machine I am using to post this, / is a 40 Gb brtfs partition and /home is 100 (also btrfs) - but 85Gb are free, whereas the / has only 18 free. Also, a recent DistroWatch review mentioned that the snapshots don't include /home so that's why I decided to use ext4 for that. (Maybe an internal /home subvolume would be included, however).

    I might delete the two partitions and make a new one of 75Gb but leave it unformatted and let oSUSE do what it wants.

    NILFS2 might be a good option and is supported, apparently.

    The partitions on sda are in reverse order. IOW, I made them from the outside in (from the end, to the beginning), except for partitions 1 and 3 (2 is the extended partition), and 1 is at the end and 3 at the beginning of the disk,/ both outside the extended and each is only 1 Gb.

    Two other distros are on sda and only one boots (Sparky - Manjaro doesn't). Each has a / and a home. That explains the number of partitions. With oSUSE, there are six plus the extended and the two little ones at the ends. (There is no sda4).

    Thanks for taking a look.

    Well the idea of a separate home is to make migration and backup much much easier. So even if /home is created by BTRFS the mount should override it and be used as the true /home

    I was able to overcome that problem. When the installation finally began it was programmed to use sda11 as /home. The hang up was due to what the installation called the wrong fs (file system, I assume). Then, it began to download everything again, which I had no desire to do. So I'll try installing from the Live DVD (900 Mb won't fit on a CD) to unformatted partitions - otherwise, the installation is going to use all the free space there is, and leave none for anything else. And if I need to install more items I can use the net install disk to do an upgrade.
