Updating to Satellite 6.16 and RHEL9
Satellite 6.16 has been released, and it's a good time to get my lab systems updated to the latest version :-)
The process is fairly similar to my previous post for Upgrading Satellite 6.11 from RHEL7 to RHEL8
Anyhow, I found a couple of snags related to leapp (limit of file descriptors) and a Jira issue that is still to be published that will make you want to delay your RHEL9 update for a couple of weeks.
The whole process is documented in the Satellite 6.16 - Upgrading Red Hat Satellite chapter.
Satellite 6.15 to 6.16 Upgrade (RHEL8)
This process is the same as previous versions, with the one caveat that now
satellite-maintain supports three different verbs:
-
satellite-maintain self-upgradeto update the satellite-maintain tools. -
satellite-maintain update run -yto update RHEL+Satellite within the same Satellite version (6.x). -
satellite-maintain upgrade run -yto update RHEL+Satellite to the next Satellite version (6.x+1).
Now the update process itself:
root@sat.p1.lab ~ # satellite-maintain self-upgrade
Running Enables the specified version's maintenance repository and,
updates the satellite-maintain packages
================================================================================
Update package(s) rubygem-foreman_maintain, satellite-maintain: [OK]
--------------------------------------------------------------------------------
root@sat.p1.lab ~ # time satellite-maintain upgrade run -y
Checking for new version of satellite-maintain...
Security: kernel-core-4.18.0-553.27.1.el8_10.x86_64 is an installed security update
Security: kernel-core-4.18.0-553.8.1.el8_10.x86_64 is the currently running version
Nothing to update, can't find new version of satellite-maintain.

Note that the satellite-maintain upgrade process waits until the data migration
tasks mentioned above are done. Once it finishes, it's safe to start/stop the
Satellite services or reboot the system (eg, to prepare for Leapp).
Leapp upgrade to RHEL9
This process is documented in the Satellite 6.16 - Upgrading Red Hat Enterprise Linux on Satellite or Capsule chapter.
root@sat.p1.lab ~ # dnf install --disableplugin=foreman-protector install leapp leapp-upgrade-el8toel9
The following answerfile can be created once you ensure VDO is not in use in your RHEL8 system:
root@sat.p1.lab ~ # cat /var/log/leapp/answerfile
[check_vdo]
# Title: None
# Reason: Confirmation
# ============================= check_vdo.confirm =============================
# Label: Are all VDO devices, if any, successfully converted to LVM management?
# Description: Enter True if no VDO devices are present on the system or all VDO devices on the system have been successfully converted to LVM management. Entering True will circumvent check of failures and undetermined devices. Recognized VDO devices that have not been converted to LVM management can still block the upgrade despite the answer.All VDO devices must be converted to LVM management before upgrading.
# Reason: To maximize safety all block devices on a system that meet the criteria as possible VDO devices are checked to verify that, if VDOs, they have been converted to LVM management. If the devices are not converted and the upgrade proceeds the data on unconverted VDO devices will be inaccessible. In order to perform checking the 'vdo' package must be installed. If the 'vdo' package is not installed and there are any doubts the 'vdo' package should be installed and the upgrade process re-run to check for unconverted VDO devices. If the check of any device fails for any reason an upgrade inhibiting report is generated. This may be problematic if devices are dynamically removed from the system subsequent to having been identified during device discovery. If it is certain that all VDO devices have been successfully converted to LVM management this dialog may be answered in the affirmative which will circumvent block device checking.
# Type: bool
# Default: None
# Available choices: True/False
confirm = True
root@sat.p1.lab ~ # leapp preupgrade
root@sat.p1.lab ~ # time leapp upgrade && reboot
[...]
Again, at this point leapp will perform the OS upgrade, perform a Selinux relabel of all files and re-run the Satellite installer once in RHEL9.
Note that at this time the following issue missing PES event to remove shim-ia32 when upgrading to RHEL9 is still pending to be released. It should be fixed in the next few days.
# cat /etc/redhat-release
Red Hat Enterprise Linux release 9.4 (Plow)
# rpm -qi satellite
Name : satellite
Version : 6.16.0
Release : 2.el9sat
Architecture: noarch
Install Date: Tue 05 Nov 2024 05:31:57 PM EST
All in all, a very painless upgrade that removes all requirements to have RHEL8 in your environment. Go RHEL9!
Happy hacking!
