      Section: - GUIDED EXERCISE: CUSTOMIZING TUNED PROFILES
      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.

      Preparing servera for lab exercise work:

      ยท? Check servera connectivity.................................. SUCCESS

      [student@workstation ~]$ ssh student@servera
      Activate the web console with: systemctl enable --now cockpit.socket

      [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.
      [root@servera ~]#
