Hi, I'll create new cluster for 3 nodes that maybe expand.
If I add node to cluster, Should I stop it to set Erasure Coding ?
Or Should I set Erasure Coding at create new cluster before running user VMs ?
I'm concerned about some impacts user VMs running on new cluster for that setting.

Hello @Sayo 

You don’t need to stop the cluster to enable EC. You can enable it any time using Prism Web UI but you need at least 4 nodes to enable it. 

The following recommendations of EC may help you to clear some doubts regarding the technology. Erasure Coding Recommendation
