Description of problem:
on RHVH 4.1 Host, "tuned-adm verify" verification command failed.
Version-Release number of selected component (if applicable):
vdsm-4.19.36-1.el7ev.x86_64
tuned-2.8.0-5.el7.noarch
How reproducible:
Always
Steps to Reproduce:
1. Login to RHVH 4.1 host as root user.
2. run command "tuned-adm verify".
Actual results:
# tuned-adm verify
Verification failed, current system settings differ from the preset profile.
You can mostly fix this by Tuned restart, e.g.:
service tuned restart
Sometimes (if some plugins like bootloader are used) also reboot is required.
See tuned log file ('/var/log/tuned/tuned.log') for details.
----
The "/var/log/tuned/tuned.log" file contains following error :
2018-04-11 11:07:14,938 ERROR tuned.plugins.base: verify: failed: 'vm.dirty_ratio' = '5', expected '40'
2018-04-11 11:07:14,971 ERROR tuned.plugins.base: verify: failed: 'vm.dirty_background_ratio' = '2', expected '5'
Expected results:
# tuned-adm verify
Verfication succeeded, current system settings match the preset profile.
See tuned log file ('/var/log/tuned/tuned.log') for details.
Additional info:
# tuned-adm active
Current active profile: virtual-host
The "vm.dirty_ratio" and "vm.dirty_background_ratio" set by tuned 'virtual-host' profile. These values are overwritten by following vdsm settings.
-->
# cat /etc/sysctl.d/vdsm.conf | grep vm.dirty
vm.dirty_ratio = 5
vm.dirty_background_ratio = 2
-->
================================
The tuned runs `sysctl --system` to reapply sysctl settings from sysctl.d, this can be changed in "/etc/tuned/tuned-main.conf" by setting reapply_sysctl = 0 (just remember to restart tuned and reapply the tuned profile).
So you need to make following changes in '/etc/tuned/tuned-main.conf',
1. open the file /etc/tuned/tuned-main.conf
reapply_sysctl = 1
Change it to
reapply_sysctl = 0 <<==== change
Save the file.
2. Restart the tuned service,
# service tuned restart
3. Now run,
# tuned-adm verify
This should complete successfully.
Test version:
rhvh-4.1-0.20180410.0+1
# 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.
