I don't have access to any internal posts on this bugzilla, but I just wanted to mention that there is an external customer who is unable to deploy OCP on his IBM POWER9 system. He opened his original support case on 7 July. If there is any additional data to collect, or any workaround which might help, I'm sure he would appreciate an update sooner rather than later. Hi Rob, We may need additional clarification here. Are you unable to install any 4.3/4.4 on ppc64le at all? What specific release version of OCP are you using? Which method are you using to deploy OCP? Hey, we tried to install 4.3.18 and 4.4.9 (both latest versions at the time of installation). We used this specific version from the installer (for 4.4.9 and I ): openshift-install 4.4.9 built from commit 1541bf917973186bbab6a5f895f08db4334a5d9a release image quay.io/openshift-release-dev/ocp-release@sha256:ae48474c6fcd0666a672ce2a449736a2549693c04186ea588e37477635c976a6 We followed the standard installation guide (https://docs.openshift.com/container-platform/4.4/installing/installing_ibm_power/installing-ibm-power.html) with IPs via DHCP. Duplicate of https://bugzilla.redhat.com/show_bug.cgi?id=1812126 This is resolved in 4.5. If you would like the installation to succeed on 4.3/4.4 the number of cores assigned to the master nodes should be 2. Which on SMT=8 leads to 16 threads. The master nodes can be resized after the initial install. Hi team! This is a duplicate of an issue that was discovered in the 4.3 timeframe,and ultimately fixed in 4.5. Some additional context from Manoj Kumar: [This issue is related to] large page size and the kernel/cgroup caches being scaled to the number of virtual CPUs/threads. The workaround is to: Install with the default/minimum size of the master node (as in the documentation). 2 Cores, on SMT=8. This information should already be present in the documentation. *** This bug has been marked as a duplicate of bug 1812126 *** |
