10/12/2023, 8:43 AMbesides, if I want to adjust some rke2 nodes’ resources like cpu and memory, could that be done inside the rancher?

10/12/2023, 9:02 AMIf only Rancher installed, just use docker install. I use the docker install for the Rancher UI that manage 15 clusters and already run for 3 years

10/12/2023, 9:03 AMBut don't forget to regularly backup the rancher docker 😃

10/12/2023, 9:34 AM@mysterious-london-79865 great thanks for your reply.
I am sorry for my unclear statement.
I am using rancher to create rke2 cluster on top of the vsphere virtualization solution, which the rancher is connected with vcenter and could talk to vcenter and let it to create some virtual machines and turn these vms into rke2 master and worker nodes.
I am sorry that I didn't get your point about how longhorn will take effect in that progress.
Could you share with me more information about that. great thanks.

10/12/2023, 9:38 AMThe RKE2 cluster deployment nodes have the disk, right?

10/12/2023, 9:40 AMIf you have enough disk space, you can integrate of the rest of the disk in the nodes into Storage in the Kubernetes using Longhorn for save the PVC.

10/12/2023, 9:51 AMyes. that’s right. my problem is that if I have no vSAN. how could I provision disks to create rke2 nodes.

10/12/2023, 9:57 AMIn this point, I just little bit confuse..
Is it the process to build the rke2 nodes or the rke2 Kube cluster already up and running?
If the build rke2 nodes, just add the disk from the vCenter, so the VM will have adequate diskspace, If you want to unified the available disk space from the nodes, just install Longhorn from Rancher UI, then the available disk will act like vSAN in the Kube cluster

10/12/2023, 12:41 PMthanks for your reply. I am sorry for my unclear.
I am building rke2 nodes, my problem is that if it needs vSAN or not. if there isn’t the need of vSAN, it means rancher has a knowledge about the mapping of physical machine and datastore on it. so rancher could find the right disk for the VM.
I am not sure if I understand it correctly.
