Hi 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. ![image](https://us1.discourse-cdn.com/elastic/original/3X/2/6/261e2aa7a9dbc5e1c62dc8e1da5c453c5b6ce312.png) Happy to get some help/tips.
