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).

Doc Text:
Cause: Previously there was an typo in the tuned-adm code regarding automatic daemon restart. Consequence: If tuned-adm command was run and if it found out that tuned daemon is not running, it tried to restart it, but this attempt failed with the traceback. If tuned daemon was running (the default, expected state), everything worked as expected. Also daemon restarts through systemd worked as expected. Fix: The tuned-adm code was fixed. Result: Now the tuned daemon restart attempt performed by tuned-adm doesn't end with traceback.

# systemctl status tuned | grep Active
   Active: active (running) since St 2015-09-23 12:36:15 CEST; 1s ago

# vim /etc/tuned/tuned-main.conf
# cat /etc/tuned/tuned-main.conf
daemon = 0
dynamic_tuning = 0
sleep_interval = 1
update_interval = 10

# systemctl restart tuned

# systemctl status tuned | grep Active
