Configuring btrfs and quotas

[Alex Gooch]

Hello all:

I was previously attempting to build btrfs over lvm, but it seems that is not possible (from a previous conversation posted in 2016). Rather than continuing to fight with that, I have decided to just create the whole systemdisk as btrfs.

I am attempting to build a btrfs oem system, to be installed on a bare metal machine. Documentation shows that we can set quotas within the xml file:

<image schemaversion="8.0" name="openSUSE-Leap-15.1"> <type image="oem" filesystem="btrfs"> <systemdisk name="vgroup" preferlvm="true"> <volume name="usr/lib" size="1G" label="library"/> <volume name="@root" freespace="500M"/> <volume name="etc_volume" mountpoint="etc" copy_on_write="false"/> <volume name="bin_volume" size="all" mountpoint="/usr/bin" quota="2G"/> </systemdisk> </type> </image>

When I attempt this in my build, I get a failure with multiple errors (e.g. shown below):

/var/tmp/kiwi_xslt-6sfnzrs2:35:49: error: attribute "quota" not allowed here; expected attribute "arch", "copy_on_write", "filesystem_check", "freespace", "label", "mountpoint", "parent" or "size"

The relevant piece of my appliance.kiwi file is shown below:

        <type

            image="oem"

            bootpartition="true"

            bootpartsize="1024"

            efipartsize="512"

            filesystem="btrfs"

            initrd_system="dracut"

            installiso="true"

            installboot="install"

            target_removable="false"

            firmware="efi"

            kernelcmdline="rd.kiwi.oem.maxdisk=1T"

        >

            <machine memory="512" guestOS="suse" HWversion="4">

                <vmdisk id="0" controller="ide"/>

                <vmnic driver="e1000" interface="0" mode="bridged"/>

            </machine>

            <!--<bootloader name="grub2" console="serial" timeout="10"/>-->

            <oemconfig>

                <oem-unattended>true</oem-unattended>

                <oem-swapsize>1024</oem-swapsize>

                <oem-multipath-scan>false</oem-multipath-scan>

            </oemconfig>

            <systemdisk preferlvm="false">

                <volume name="@root"/>

                <volume name="var" quota="15G"/>

                <volume name="var/log" quota="12G"/>

                <volume name="var/lib" quota="5G"/>

                <volume name="var/lib/docker" quota="150G"/>

                <volume name="var/tmp" quota="100G"/>

                <volume name="var/opt" quota="6G"/>

                <volume name="home" quota="5G"/>

                <volume name="usr/local" quota="5G"/>

                <volume name="tmp" quota="5G"/>

                <volume name="systems" quota="5G"/>

                <volume name="opt" quota="5G"/>

                <volume name="srv" quota="5G"/>

                <volume name="snapshots"/>

                <!--

                <volume name="boot/grub2/x86_64-efi"/>

                <volume name="boot/grub2/i386-pc"/>

                -->

            </systemdisk>

If we are not supposed to set quotas here, where else should this be done? Are you able to review this block of the xml code and let me know if I am doing something wrong? Any suggestions would be helpful. Thank you all in advance.

Hi Alex,

Sounds like a too old kiwi version. You can take a look at the
integration test that uses quota here:

https://build.opensuse.org/projects/Virtualization:Appliances:Images:Testing_x86:tumbleweed/packages/test-image-disk/files/_service:obs_scm:appliance.kiwi?expand=1

quota support is available in v10.1.13 or later
