I create an ISO with autoinstall that needs to be generic. It should work on VMs, physical machines with legacy bios, EFI bios, with and without RAID.
In my autoinstall.yml, I don't have anything related to storage (as I want it to be as generic as possible for all the platforms):
#cloud-config
autoinstall:
version: 1
identity:
hostname: fooapp
username: foouser
password: "XXXXXXX"
network:
ethernets: {}
version: 2
source:
id: ubuntu-server-minimal
early-commands:
- cat /cdrom/casper/install-sources.yaml | awk 'NR>1 && /^-/{exit};1' > /run/my-sources.yaml
- mount -o ro,bind /run/my-sources.yaml /cdrom/casper/install-sources.yaml
late-commands:
- cp -r /cdrom/copy_to_iso/ /target/opt/
user-data:
runcmd:
- |
echo -e "\033[32mDuring installation, please don't touch until the installation will be finished....\033[0m"
mkdir -vp /opt/INIT/ >> /root/application_installation.log 2>&1
mv -v /opt/copy_to_iso/upgrade_or_install_packages/ /opt/ >> /root/application_installation.log 2>&1
mv -v /opt/copy_to_iso/foo_installation/* /opt/INIT/ >> /root/application_installation.log 2>&1
mv -v /opt/copy_to_iso/application_scripts /opt/application_scripts >> /root/application_installation.log 2>&1
rm -rvf /opt/copy_to_iso >> /root/application_installation.log 2>&1
bash -x /opt/application_scripts/copy_system_files.sh >> /root/application_installation.log 2>&1
bash -x /opt/application_scripts/setup_system_config.sh install_mode >> /root/application_installation.log 2>&1
echo -e "\033[32mInstallation was completed...\033[0m"
The installation of the ISO is done successfully in all the platforms, except EFI bios with RAID1 (UEFI Option ROM Control > Virtual RAID on CPU). Note - without RAID, same platform, it works.
During the ISO installation, it fails on the stage of cmd-install/stage-partitioning/builtin/cmd-block-meta/clear-holders on the following error:

Do you have a suggestion? I tried to add to early-commands: the following -
- mdadm --manage --stop /dev/md126
- mdadm --manage --stop /dev/md127
It didn't help; same error.
