I am trying to increase my Master Nodes with more diskspace. The two nodes are used with 82 and 83% diskspace. When I try an config change from 1 to 2 availability zones it fails by the step "Calling Elasticsearch node shutdown API" and takes about 2 hours. The same if when I tried just to increase the diskspace or both together. It creates some new instances but it fails everytime and stays in the maintenance mode.
Happy to get some help/tips. BR afmin
