Note: This bug is displayed in read-only format because the product is no longer active in Red Hat Bugzilla.

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). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Description of problem:


Version-Release number of selected component (if applicable):

tuned-2.9.0-1.el7.noarch

How reproducible:

Create a custom profile named test-profile, with the following configuration. 

/etc/tuned/test-profile/tuned.conf

[main]
include=throughput-performance

[sysctl]
replace=1
vm.swappiness=15


Steps to Reproduce:
1. tuned-adm profile test-profile
2. tuned-adm active shows test-profile


Actual results:

[root@XX tuned]# sysctl vm.swappiness
vm.swappiness = 10
[root@XX tuned]# sysctl vm.dirty_ratio
vm.dirty_ratio = 40 # This should the default value for vm.dirty_ratio and show the configured value on throughput-performance profile


Expected results:

[root@XX tuned]# sysctl vm.swappiness
vm.swappiness = 10
[root@XX tuned]# sysctl vm.dirty_ratio
vm.dirty_ratio = 20 # This should be proper value for vm.dirty_ratio as this is the default on RHEL 7.5

Additional info:

Modifying the configuration for /etc/tuned/test-profile/tuned.conf

[main]
include=throughput-performance

[sysctl]
replace=true # <---- Set this to true (all lower case)
vm.swappiness=15

It works.

But the documentation from tuned.conf(5) instructs to set the value for replace to 0 or 1.

I'm a bit confused from your actual/expected results. Do I understand it correctly that this is simply a request to make 'replace=1' behave the same way as 'replace=true'?

Thanks.

Documentation doesn't reference replace=true only replace=1.

So the request will be to update the documentation or the make 'replace=1' work the same as 'replace=true'
