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the product is no longer active in Red Hat Bugzilla.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.
Cause:
Previously ktune didn't handle the /etc/sysctl.d directory nor it didn't support more multiple files with sysctl settings.
Consequence:
The /etc/sysctl.d settings whis is installed by several packages like libvirt was ignored.
Fix:
The ktune code and profiles were modified.
Result:
Now all the sysctl settings under the /etc/sysctl.d directory is loaded and then the /etc/sysctl.conf is loaded. Also the user can now specify multiple sysctl files (wildcards are also supported) to load in the tuned profiles.
Description of problem:
sysctl configuration under /etc/sysctl.d is ignored when tuned applies SYSCTL_POST (usually just /etc/sysctl.conf)
Version-Release number of selected component (if applicable):
tuned-0.2.19-11.el6.1.noarch
How reproducible:
Always
Steps to Reproduce:
1.Installed tuned
2.Pick a profile
3.
Actual results:
/etc/sysctl.d entries are ignored
Expected results:
/etc/sysctl.d entries should be respected
Additional info:
/etc/sysctl.d is already used by libvirt and vdsm
A crude fix is the following hack into the initscript:
