Description Jesse Pretorius 2021-05-27 14:06:05 UTC

This bug was initially created as a copy of Bug #1962365

I am copying this bug because the same issue applies to 16.2.



When trying to upgrade the undercloud, the following error is emitted:

Upgrade has been inhibited due to the following problems:
    1. Inhibitor: Detected loaded kernel drivers which have been removed in RHEL 8. Upgrade cannot proceed.
Consult the pre-upgrade report for details and possible remediation.


Then in /var/log/leapp/leapp-report.txt

Risk Factor: high (inhibitor)
Title: Detected loaded kernel drivers which have been removed in RHEL 8. Upgrade cannot proceed.
Summary: Support for the following RHEL 7 device drivers has been removed in RHEL 8: 
     - floppy
     - pata_acpi
Please see https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/8/html-single/considerations_in_adopting_rhel_8/index#removed-device-drivers_hardware-enablement for details.
Remediation: [hint] Please disable detected kernel drivers in order to proceed with the upgrade process using the rmmod or modprobe -r.

Just adding some docs flags to track the progress on this ticket, as docs changes will be required once this fix lands in 16.2. It affects the following modules (the workaround steps for unloading the unsupported kernel modules): 
 
* https://access.redhat.com/documentation/en-us/red_hat_openstack_platform/16.1/html-single/framework_for_upgrades_13_to_16.1/index#creating-an-upgrades-environment-file-overcloud-leapp

Thank you
