IT does not contain any usefull data yet , so I can play aorund a little bit. Have some questions. Is it possible to create a cluster with only two boxes ? I understood it is possible , but can not move VMs without service disruption. And if I want to move VMs without services disruption I need a third box. What is ceph storage for ? what is ZFS pool for ? In case I need I can add it on any of my available bays o any box ? Do pve boxes need to be on same network subnet ? I have two datacenters , I was thinking in the idea to install them on each location just for redundancy. Lets supose network connection performance is optimal ... Is there any problem with that ? Any other clustering good practice advice would be wellcome. Thanks. Libre de virus. www.avast.com <#DAB4FAD8-2DD7-40BB-A1B8-4E2AA1F9FDF2>
