Last modified: 2017-09-18 12:04:36 EDT
Description of problem: When installing Red Hat Enterprise Linux 7.4 from scratch the following warning messages are reported: 16:00:15,997 WARNING systemd:Cannot add dependency job for unit lvm2-monitor.service, ignoring: Unit not found. 16:00:15,997 WARNING systemd:Cannot add dependency job for unit systemd-tmpfiles-clean.timer, ignoring: Unit is masked. 16:00:15,997 WARNING systemd:Cannot add dependency job for unit rhel-configure.service, ignoring: Unit is masked. 16:00:15,998 WARNING systemd:Cannot add dependency job for unit rhel-autorelabel-mark.service, ignoring: Unit is masked. 16:00:15,998 WARNING systemd:Cannot add dependency job for unit rhel-autorelabel.service, ignoring: Unit is masked. 16:00:15,998 WARNING systemd:Cannot add dependency job for unit rhel-loadmodules.service, ignoring: Unit is masked. [...] 16:00:16,815 WARNING systemd:Cannot add dependency job for unit lvm2-monitor.service, ignoring: Unit not found. 16:00:16,816 WARNING systemd:Cannot add dependency job for unit systemd-tmpfiles-clean.timer, ignoring: Unit is masked. 16:00:16,816 WARNING systemd:Cannot add dependency job for unit rhel-configure.service, ignoring: Unit is masked. 16:00:16,816 WARNING systemd:Cannot add dependency job for unit rhel-autorelabel-mark.service, ignoring: Unit is masked. 16:00:16,817 WARNING systemd:Cannot add dependency job for unit rhel-autorelabel.service, ignoring: Unit is masked. 16:00:16,820 WARNING systemd:Cannot add dependency job for unit rhel-loadmodules.service, ignoring: Unit is masked. Seems we are missing some dependencies or have other issues with parts of `systemd` in the installer. So far I did not see that these warnings are causing issues, but we should definitely investigate them and address it. Version-Release number of selected component (if applicable): - 21.48.22.121-1 How reproducible: - always Steps to Reproduce: 1. Install Red Hat Enterprise Linux 7.4 using kickstart 2. Inspect `/var/log/anaconda/syslog` after the installation completed 3. Actual results: Following messages are being reported when certain `systemd` activity are being triggered. 16:00:16,815 WARNING systemd:Cannot add dependency job for unit lvm2-monitor.service, ignoring: Unit not found. 16:00:16,816 WARNING systemd:Cannot add dependency job for unit systemd-tmpfiles-clean.timer, ignoring: Unit is masked. 16:00:16,816 WARNING systemd:Cannot add dependency job for unit rhel-configure.service, ignoring: Unit is masked. 16:00:16,816 WARNING systemd:Cannot add dependency job for unit rhel-autorelabel-mark.service, ignoring: Unit is masked. 16:00:16,817 WARNING systemd:Cannot add dependency job for unit rhel-autorelabel.service, ignoring: Unit is masked. 16:00:16,820 WARNING systemd:Cannot add dependency job for unit rhel-loadmodules.service, ignoring: Unit is masked. Expected results: No warning message to be reported during the installation. Respectively no "Cannot add dependency job for unit" warning message when running `systemd` activtiy. Additional info:
Looks to me like there are missing parts in the installation environment. Lorax is the component responsible for creation of stage2 image. Changing component to lorax.
https://github.com/rhinstaller/lorax/pull/237 fixes the 'Unit not found.' but there isn't really anything to do about the masked units that's a normal response when you've masked services that cannot be disabled because they are in /usr/lib/systemd/ I've also removed the lvm2-activation-generator which was also logging an error.
