Abstract
The technology described herein is directed towards automating/orchestrating removal of one or more nodes of a node cluster, including in a cloud computing environment in which nodes in a cluster map to deployed virtual machines. An automated workflow can be started based on user input specifying an amount of capacity to remove, which corresponds to one or more nodes to remove. In a node cluster with associated nodes arranged into pools of nodes, node removal is per node pool. An orchestrated workflow performs pre-validation based on satisfying appropriate removal criteria, followed by data move and node removal jobs, and post-validation to check that removed capacity is generally as specified and that the remaining node layout is appropriate. Data of any removed node is re-protected, such as by restoring data from removed nodes to remaining cluster nodes in a manner that maintains the data with a data protection scheme.
