This bug is blocking Logging. With this bug, the ES pods could not start, and Logging stack could not work. This is very likely a bug associated with the recent switch of the base image for containerized tuned from RHEL 7.6 to 7.7. RHEL 7.6 ships tuned 2.10, RHEL 7.7 tuned 2.11. Investigating further. Linking an associated tuned 2.11 BZ: https://bugzilla.redhat.com/show_bug.cgi?id=1739418 This will also likely affect the Node Tuning Operator functionality in OCP 4.2 with a switch to RHEL 7.7 container image. the workarount is to set vm.max_map_count=262144 by hack into the node where the ES pod may located. The same version tuned(tuned-2.11.0-5.el7.noarch based on 7.7) works on 4.2. 4.2 image -> quay.io/openshift-release-dev/ocp-v4.0-art-dev@sha256:1e4a2551fbabc2082bf64feaecad2ba69ad791f62e3413a8468f204b4b3b2422 4.1.10 image -> quay.io/openshift-release-dev/ocp-v4.0-art-dev@sha256:1e4a2551fbabc2082bf64feaecad2ba69ad791f62e3413a8468f204b4b3b2422 Test blocked by https://bugzilla.redhat.com/show_bug.cgi?id=1741753 Verified in v4.1.12 Since the problem described in this bug report should be resolved in a recent advisory, it has been closed with a resolution of ERRATA.
