Testcase (Report an issue with this testcase)

Proceed in your native language if you wish. Instructions will remain in English.

This test involves installing a fresh system with zfs + encryption, then breaking the system in a post-install test step. If the system you are installing on is important to you, and you want to preserve the zfs+encryption installed system, do not do this test.

Boot up the image
If you see the GRUB boot menu you should see the following:
  • 'Try or Install Ubuntu'
  • 'Ubuntu (safe graphics)'
  • 'OEM install (for manufacturers)'
  • 'Test memory' (only on BIOS systems)

    The 'Updates and other software' screen is displayed
    On the screen 'Updates and other software', note the availability of the following components
    Available options should represent the state of your system accurately
    For Mantic and later releases, the default install is a minimal install. Releases before Mantic the default is a 'full' install, complete with other apps a user might want. The new, default, install does not include these add-ons.
    • (If network is available) 'Download updates while installing Ubuntu'
    • (If on a 'laptop') 'Is plugged to a power source'
    • 'Install third-party software...' option available
    Click on the Continue button
    The 'Installation type' screen is displayed
    Note the state of the 'Erase disk and install Ubuntu' radio button
    The 'Erase disk and install Ubuntu' radio button is selected and the 'Advanced features' button is active
    Click on the 'Advanced features...' button
    The 'Advanced Features' dialog is displayed
    Select 'Erase disk and use ZFS'
    'Erase disk and use ZFS' is selected

    If there is only one hard disk, skip to step 18 (On the 'Where are you?' screen...). Otherwise, on the 'Installation type' screen verify that the drive selected on the Select drive list corresponds to the drive on the chart (e.g /dev/sda)
    Selected drive is displayed on the chart
    Verify that the full drive space is allocated
    Full drive space is allocated for installation
    Click on the Install Now button
    The 'Where are you?' screen is displayed

    Upon login, open a terminal, run the following commands and verify it matches the output
    $ zfs mount | sort
    bpool/BOOT/ubuntu_UUID /boot
    rpool/ROOT/ubuntu_UUID /
    rpool/ROOT/ubuntu_UUID/srv /srv
    rpool/ROOT/ubuntu_UUID/usr/local /usr/local
    rpool/ROOT/ubuntu_UUID/var/games /var/games
    rpool/ROOT/ubuntu_UUID/var/lib/AccountsService /var/lib/AccountsService
    rpool/ROOT/ubuntu_UUID/var/lib/apt /var/lib/apt
    rpool/ROOT/ubuntu_UUID/var/lib/dpkg /var/lib/dpkg
    rpool/ROOT/ubuntu_UUID/var/lib/NetworkManager /var/lib/NetworkManager
    rpool/ROOT/ubuntu_UUID/var/lib /var/lib
    rpool/ROOT/ubuntu_UUID/var/log /var/log
    rpool/ROOT/ubuntu_UUID/var/mail /var/mail
    rpool/ROOT/ubuntu_UUID/var/snap /var/snap
    rpool/ROOT/ubuntu_UUID/var/spool /var/spool
    rpool/ROOT/ubuntu_UUID/var/www /var/www
    rpool/USERDATA/root_0y7dio /root
    rpool/USERDATA/u_0y7dio /home/u
    Run the lsblk command and check for this line in the output:
    cryptoswap 252:1 0 2.6G 0 crypt [SWAP]
    Run the following command to place a file under ~:
    echo "hello" > /home/$USER/hello
    We're going to check for this file in a later part of this test case.
    Shut down the installed system.
    Using the same .iso, boot into the iso using the disk that you just completed the installation on.
    Go through the grub menu and instead of installing, select "Try Ubuntu".
    Open a terminal window, and enter the following:
    sudo su
    fdisk -l /dev/$disk # Where $disk is the disk you completed the install on.
    The output should include something similar to the following:
    /dev/vda1 2048 4095 2048 1M BIOS boot
    /dev/vda2 4096 1054719 1050624 513M EFI System
    /dev/vda3 1054720 9037823 7983104 3.8G Linux swap
    /dev/vda4 9037824 13178879 4141056 2G Solaris boot
    /dev/vda5 13178880 83884031 70705152 33.7G Solaris root
    For the rest of this testcase, we will use vda in place of $disk.
    Check for the zfs pool names:
    blkid /dev/vda*
    /dev/vda: PTUUID="7dd06581-4867-4632-9a90-23d9c472b039" PTTYPE="gpt"
    /dev/vda1: PARTUUID="c061c581-06c1-43e2-8680-d353771bf341"
    /dev/vda2: UUID="2748-996B" BLOCK_SIZE="512" TYPE="vfat" PARTLABEL="EFI System Partition" PARTUUID="f7c29e7e-687f-4cbb-a1a1-f8876f809a64"
    /dev/vda3: UUID="8c1d6471-1f90-4212-8fbd-097a9a9ad909" TYPE="crypto_LUKS" PARTUUID="8ff61492-9bda-40fe-94a8-7d6fe4d220cb"
    /dev/vda4: LABEL="bpool" UUID="8851209407646287070" UUID_SUB="1631837207961890120" BLOCK_SIZE="4096" TYPE="zfs_member" PARTUUID="8b8b8818-cc94-42bd-b23d-cf7c9e9b73ff"
    /dev/vda5: LABEL="rpool" UUID="4519996901618382696" UUID_SUB="8860607139843727357" BLOCK_SIZE="4096" TYPE="zfs_member" PARTUUID="5cc65ba9-8ef4-475c-a107-cc130a9be1be"
    Here, the zfs pool names are the labels of the drives of TYPE "zfs_member". So in this case, the zfs pools are "bpool" and "rpool".
    Now, we will import the pool of the root partition:
    zpool import rpool
    Check the output of the following command to see that rpool is imported:
    zpool status -v
    After entering the following command, enter your security key in the prompt:
    cryptsetup luksOpen /dev/zvol/rpool/keystore keystore
    Mount the keystore:
    mkdir /mnt/keystore
    mount /dev/mapper/keystore /mnt/keystore
    Copy the key to necessary location:
    mkdir -p /run/keystore/rpool
    cp -b /mnt/keystore/system.key /run/keystore/rpool
    Make the root pool mountable:
    zfs set canmount=on rpool
    Load the zfs key:
    zfs load-key rpool
    Check for the pool associated with the userdata:
    zfs list -o name,type,keylocation
    You want to find a line in the output of the above command in this format:
    $poolname/USERDATA/$username_$hash
    For example: rpool/USERDATA/tim_aqj46w
    Set mountpoint for USERDATA:
    mkdir -p /mnt/rpool/USERDATA/tim_aqj46w
    zfs set mountpoint=/mnt/rpool/USERDATA/tim_aqj46w rpool/USERDATA/tim_aqj46w
    Mount the pool:
    zfs mount -a
    Check for the test file we made earlier, for example:
    cat /mnt/rpool/USERDATA/tim_aqj46w/hello
    The output should be "hello"
