Language: en-US (English)|
Workaround:

Description: In section CUSTOMIZING TUNED PROFILES recommended to verify created custom profile: "After activating a custom tuned profile, use the tuned-adm verify command to verify that the currently active profile". There is no tuned-adm verify example in guided exercise for this section, however when students try to verify prepared custom profile they get an error, concerning original profiles:

[student@workstation ~]$ lab kerneltuning-customize start

Starting lab.

[student@servera ~]$ sudo -i
[sudo] password for student:
[root@servera ~]# tuned-adm verify
Verification failed, current system settings differ from the preset profile.
You can mostly fix this by restarting the Tuned daemon, e.g.:
systemctl restart tuned
or
service tuned restart
Sometimes (if some plugins like bootloader are used) a reboot may be required.
See tuned log file ('/var/log/tuned/tuned.log') for details.
