Description Martin Sivák 2021-04-09 08:45:24 UTC
Description of problem:

The kernel bug in the HRTICK subsystem was resolved and the fixed versions are getting into RHCOS now. So it is time for us to re-enable stalld in the PAO tuned profile.

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

Fix is present in:
- kernel-4.18.0-240.20.1.el8_3 (released on Apr 6th, see bug 1930735)
- as well as RHEL 8.4 nightly (bug 1912118)

RHCOS that contains this kernel:

4.7 - builds from Apr 8th and Apr 9th have kernel-4.18.0-240.22.1.el8_3
4.8 - none yet (last build from Apr 4th is too old)


Action items:

Lets prepare the patches for 4.8 and merge them to 4.8 branch once there is a sane RHCOS build and backport to 4.7 right after that (have the patches ready).

Comment 2 Dave Cain 2021-04-09 14:37:55 UTC
What happens with existing deployments of OpenShift that are upgraded?  Will stalld be re-enabled on those clusters, or just net-new installs?

Comment 3 Martin Sivák 2021-04-09 15:09:44 UTC
I think it will be re-enabled, but obviously we need to test and verify that.

Comment 4 Martin Sivák 2021-04-12 08:35:41 UTC
The current OCP 4.7 nightlies already contain the right kernel:

4.7.0-0.nightly-2021-04-10-082109
https://openshift-release.apps.ci.l2s4.p1.openshiftapps.com/releasestream/4.7.0-0.nightly/release/4.7.0-0.nightly-2021-04-10-082109
https://releases-rhcos-art.cloud.privileged.psi.redhat.com/contents.html?stream=releases%2Frhcos-4.7&release=47.83.202104090345-0

However 4.8 nightlies have been broken for some time time and the RHCOS there is not yet up-to-date

Comment 9 Martin Sivák 2021-04-21 10:53:13 UTC
Awesome:


[service]
service.stalld=start,enable

This is what we were looking for.
