RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.
Description of problem:
When upgrading a Z guest using Leapp, it ends up missing devices after switch root (all the ones not explicitly enabled on the kernel command line):
- disks
- network devices
This is because the "device_cio_free.service" unit is not enabled. This service is used to whitelist the devices.
This service has a systemd preset shipped by redhat-release package, but apparently leapp doesn't enable the presets upon upgrade:
-------- 8< ---------------- 8< ---------------- 8< ---------------- 8< --------
# grep device_cio_free.service /usr/lib/systemd/system-preset/90-default.preset
enable device_cio_free.service
-------- 8< ---------------- 8< ---------------- 8< ---------------- 8< --------
I don't know if leapp should use "systemctl preset-all" or only enable individual units.
Indeed, using "systemctl preset-all" on an upgraded system enables more units, including "multipathd.socket" and "selinux-autorelabel-mark.service".
Version-Release number of selected component (if applicable):
leapp-repository-0.15.0-6.el7_9
How reproducible:
Always
Steps to Reproduce:
1. Update a Z guest
2. Check "device_cio_free.service" unit status
Actual results:
Not enabled / didn't run
Expected results:
Enabled and executed
