Hi elasticsearch team, I have this case where my VM size is 110gb. Then my freshly installed elasticsearch have 58gb maximum disk available. How do I Optimize my elasticsearch disk available? This cluster is a single node, and I want to increase the size without adding new node into it. and suggestion will be appreciated. thank you team. ---
