Hello, With reference to http://download.parallels.com/doc/pcs/html/Parallels_Cloud_Server_Users_Guide/37581.htm https://kb.plesk.com/en/119207 about spare node which talking "empty Hardware Node with enough resources and a license". Does it means I need to assign a node with no any CTs running inside? What if that node have few CTs running there. Is it still assigned as a SPARE node? Also, is it I should manual assign which node work as a SPARE? Thanks!
