Problem installing manjaro 18.0.4 using calamares in a LVM environment

I downloaded manjaro-kde-18.0.4-stable-x86_64.iso and used dd to write to a USB. I checked the sha1 of the USB which matched that of the ISO. I have the following structure of my HDD:
sda1 -> 500MB (esp, boot)
sda2 -> 118GB LVM2 (VG LinuxSystem)-> LV1 -> 8GB set aside for Linux swap
LV2 -> 50GB set aside for Linux system
LV2 -> 66.85GB set aside for Linux home
sda5 -> 170GB NTFS data partition
sda6 -> 170GB luks(ext4) data partition
I want to install Manjaro in this system and I do not have an internet connection (this ruled out architect).
When starting up calamares, everything runs fine and I first flag sda1 as /boot/efi. Then I flag the respective LVs with the correct mount points (swap, / and /home) (also format the partitions as it contains data from a previous installation). I set up the user and password. But when I proceed with the installation, calamares exits with the error message that it cannot format partition " /dev/LinuxSystem/LinuxBase on disk 'LinuxSystem'"

Detailed output from calamares:

[manjaro x86_64]# calamares -D8

It seems that "ClearMountsJob" of calamares is closing the dev mapper so that the mkfs.ext4 has nothing to partition!!

Can anyone suggest how to get around this problem?

Also is there a way to install Manjaro from CLI but without the internet connection? I tried to use "setup" from CLI but it aborts since I have no internet connection.

Can anyone guide me to manually install Manjaro, such as by extracting the desktopfs.sfs and roootfs.sfs files in the LVs and then run the appropriate commands (mkinitcpio grub etc...)?

Sounds very familiar to me. I was able to install Illyria (Gnome version) in my Acer Spin 1 laptop using a workaround. This laptop requires UEFI boot, it doesn't support Legacy/BIOS mode.

My setup is as follows:
EMMC drive with Windows (not to be used at all)
USB 64GB thumb drive. Manjaro will be installed here using the following partitions:

  • sda1 = /boot/efi
  • sda2 = /boot
  • sda3 = Linux LVM
    • volgroup0
      • lv_rootmanjaro
      • lv_swap

Disclaimer: I have performed a Manjaro fresh install on my laptop. The steps I'm about to mention will erase the contents of the drive you use, so take them as an example and perhaps avoid the instructions/commands that format things that you want to keep :wink:

Once Manjaro live is running, open a terminal and become root with 'sudo -i'. If any of your drives/partitions are detected and mounted, unmount them.
Run 'fdisk /dev/sda' (your disk could be detected as a different device, sdb...)

  • Create a new GUID partition table on the Thumb drive where you want to install Manjaro (hit 'g' in fdisk)
  • Create a new partition for /boot/efi (n, 1, enter, +256M, t, 1)
  • Create a new partition for /boot (n, 2, enter, +512M)
  • Create a new partition for LVM (n, 3, enter, enter, t, 3, 31)
  • Write changes (w)

Format the /boot/efi and /boot partitions:
mkfs.fat -F32 /dev/sda1
mkfs.ext2 /dev/sda2

Create the LVM structure:
pvcreate /dev/sda3
lvcreate -L 40GB volgroup0 -n lv_rootmanjaro
lvcreate -L 2GB volgroup0 -n lv_swap
vgscan
vgchange -ay

Format the LVM volumes:
mkfs.ext4 /dev/volgroup0/lv_rootmanjaro
mkswap /dev/volgroup0/lv_swap

On the Manjaro graphical installer, format again the sda1 & sda2 partitions with their respective filesystems.
Select the appropriate mount points:
sda1 -> /boot/efi
sda2 -> /boot
/dev/volgroup0/lv_rootmanjaro -> /

(optional) If you are using EFI "Secure Boot" in your setup, add a new Secure entry: Look for , EFI, bootx64.efi and give it a name. In boot order preferences select as the first option “Manjaro”, GRUB is able to boot Manjaro and Windows.

In conclusion, I think there is a bug on how the graphical installer of Manjaro deals with LVM setups. There are some redundant steps (like formatting twice the /boot partitions) but it was the only way I found to workaround this issue.

It will be great if these problems are solved for next releases, if not at least hope this helps.

I have similar structure to the one above, except my LVM is encrypted with Luks. It's just a test environment, to see how Manjaro handles FDE. I have been using Ubuntu and Mint for years, because the Ubuntu installer has more or less the only installer that lets you properly select manually configured Luks/LVM volumes for your mount points. Most installers can't even find them during partitioning. Manjaro does, but screws everything up, by closing them before installation. So far my testing has brought me no further than to the installation process, before it crashes.

Hope this will get fixed at some point, so that I can finally take this distro for a proper test run. But so long as FDE attempts causes problems, it will have to be put on hold.

Maybe this is fixed in the new version (18.1.0) of Manjaro.

Sorry for replying so late. After the failed installation, I replaced Manjaro with Fedora 31 (when it came out). The installation system of Fedora is IMO better than that of Manjaro but I liked the installed system Manjaro better (Fedora has many bugs) and again moved back to Manjaro 18.1.2. I still was not able to install Manjaro in LVs. It would be nice if the same commands that Calamares runs can be run seperately from the command line...

For LVM installation, I have several times now successfully used Manjaro Architect instead of Calamares because Calamares would often fail. Architect works.

True, but it requires internet connection :cry:
