@derekwaynecarr Are Huge Pages being promoted to supported in 3.10, or will they remain in Tech Preview?

Oh, I see now that they are: #8706

+limitations. In particular, they are limited to 2Mi page sizes. THP can lead to
+performance degradation on nodes with high memory utilization or fragmentation
+due to defragmenting efforts of THP, which can lock memory pages. For this

+* The containerized mode for {product-title} is no longer supported (where
+ components run in docker containers) and the 3.10 upgrade will require you to
+ move to RPMs or system containers for the kubelet by setting
+ `openshift_use_system_containers=true`.


openshift_use_system_containers is removed in openshift/openshift-ansible#8329.

The changes will be done automatically according to the OS during the upgrade:

Atomic Host: Node service run as system container

RHEL: Node service run as rpm

+master. The 3.10 upgrade, unless you set `openshift_node_bootstrap=false` in your
+inventory, will automatically transform your nodes to use that mode.  This
+enables certificate rotation and centralized certificate management by default. Use `oc get
+csr` to see pending certificates.


openshift_node_bootstrap is also removed, please see https://bugzilla.redhat.com/show_bug.cgi?id=1567783.

All nodes must be bootstrapped.

I believe Cinder is not supported at the moment. And QE have tested EBS and GCE pDisk, but not HostPath.

Better use a different name with the snapshot name as it can confuse end user.

@liangxia I was previously instructed by @sferich888 to change it to match. Eric, can I change it back?

In section [CONTAINERIZED INSTALLATION METHOD REMOVED]
Not totally, for upgrade from v3.9 to v3.10, if standalone etcd was run as containerized on rhel, after upgrade, it will keep containerized.

ahardin-rh · 2018-07-13T16:53:00Z

@vikram-redhat I applied all of the latest edits, added in all suggested information, and added all of the latest bug descriptions to date. Although this is still a work in progress, I am going to merge this now so that the team can build on this while I'm out on PTO.
