@weihua @johnny Sorry, I'm not too sure what is being asked. Is swap memory disabled by default in 3.9? If so, I can move the "Disabling Swap Memory" section for the 3.9 guide to the "Upgrading" guide? Perhaps to here: https://docs.openshift.com/container-platform/3.7/upgrading/index.html If this is only affecting users who have upgraded to 3.9 from 3.7, then that might be the best idea. The section does not have a purpose if the reader is installing a 3.9 cluster.
(In reply to brice from comment #2) > Is swap memory disabled by default in 3.9? For 3.9 fresh install, there is an ansible-openshift option (openshift_disable_swap=false) to allow user keep swap memory on, installation is going well, no fatal error. If no set this ansible-openshift option, openshift-ansible installer would disable swap by default. > > If so, I can move the "Disabling Swap Memory" section for the 3.9 guide to > the "Upgrading" guide?

I think we need link the "Disabling Swap Memory" section in the "Upgradeing" guide, but not move.
