Issue

Description of problem: Using custom drivers is basically unsupported as it could be risky and in the worst case lead to a broken system. That said, it would be a great feature and a customer requested how to do this. As they agreed to make some tests in their environment I suggested the below recipe. Customer is using a NAS that uses arcmsr as a storage driver. This driver was present in the RHEL7 branch but has been removed from RHEL 8 and beyond. The procedure worked for the customer. Version-Release number of selected component (if applicable): leapp-upgrade-el7toel8-0.17.0-1.el7_9 DISCLAIMER: it's not supported by Red Hat, play at your own risk! 0. Avoid the inhibitor and edit `/etc/leapp/files/device_driver_deprecation_data.json` to make Leapp believe it's still available and maintained: { "available_in_rhel": [ 7, 8 ], "deprecation_announced": "", "device_id": "", "device_name": "", "device_type": "pci", "driver_name": "arcmsr", "maintained_in_rhel": [ 7, 8 ] } , 1. Create an HTTP repo on another machine to share the RPM driver. Ensure you can curl the metadata (repodata/repomd.xml) and the rpm from the target machine. 2. On the target machine, create an additional repo (replace 192.168.122.1 by the IP of the http server used above). cat << EOF > /etc/leapp/files/leapp_upgrade_repositories.repo [drivers] name=drivers baseurl=http://192.168.122.1/drivers EOF 3. Include the RPM in the el8 target userspace container used to create the UpgradeInitramfs (/var/lib/leapp/el8userspace). To do so, edit `/usr/share/leapp-repository/repositories/system_upgrade/common/actors/commonleappdracutmodules/libraries/modscan.py`, and add 'kmod-arcmsr' to the _REQUIRED_PACKAGES array. 15 _REQUIRED_PACKAGES = [ 16 'binutils', 17 'cifs-utils', 18 'device-mapper-multipath', 19 'dracut', 20 'dracut-config-generic', 21 'dracut-config-rescue', 22 'dracut-network', 23 'dracut-tools', 24 'fcoe-utils', 25 'hostname', 26 'iscsi-initiator-utils', 27 'kbd', 28 'kernel', 29 'kernel-core', 30 'kernel-modules', 31 'keyutils', 32 'lldpad', 33 'lvm2', 34 'mdadm', 35 'nfs-utils', 36 'openssh-clients', 37 'plymouth', 38 'rpcbind', 39 'systemd-container', 40 'tar', 41 'kmod-arcmsr', # <<<<< 42 ] 4. Edit `/usr/share/leapp-repository/repositories/system_upgrade/common/actors/initramfs/upgradeinitramfsgenerator/files/generate-initram.sh` and insert the following line: --add-drivers arcmsr 81 stage "Building initram disk for kernel: $KERNEL_VERSION" 82 \dracut \ 83 -vvvv \ 84 --force \ 85 --conf "$DRACUT_CONF" \ 86 --confdir "$DRACUT_CONF_DIR" \ 87 --install "$DRACUT_INSTALL" \ 88 $DRACUT_MODULES_ADD \ 89 "$DRACUT_MDADMCONF_ARG" \ 90 "$DRACUT_LVMCONF_ARG" \ 91 --no-hostonly \ 92 --add-drivers arcmsr \ # <<<<< 93 --kver "$KERNEL_VERSION" \ 94 --kernel-image "vmlinuz-upgrade.$KERNEL_ARCH" \ 95 "initramfs-upgrade.${KERNEL_ARCH}.img" 5. Tell Leapp to add this RPM to be installed during the DNF transaction on the final target system echo kmod-arcmsr >> /etc/leapp/transaction/to_install 6. Run `leapp upgrade --debug --enablerepo drivers`
