rhel-osp-director: [Doc] Replacing Controller Nodes for 8.0 is missing. Tried to follow the steps for 7: https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Linux_OpenStack_Platform/7/html/Director_Installation_and_Usage/Replacing_Controller_Nodes.html The pcs cluster was in maintenance mode, so I couldn't even start the keystone. After manually disabling the maintenance mode on pcs cluster, still wasn't able to successfully complete re-deployment of the overcloud as mentioned in step 7 in the guide above.
