vokoscreenNG-2023-04-18_19-49-50.mp4

To Reproduce

Steps to reproduce the behavior:

1. Install Harvester with any nodes
2. Login to Rancher, import Harvester into Rancher
3. Create RKE2 cluster having 2+ volumes/networks with duplicated cluster name
4. Update volumes/networks to 1 and use another valid cluster name
5. Cluster should created with 1 volume/network

Expected behavior

Cluster's Volumes and networks should be the same as the final configuration

Environment:

• Harvester ISO version: v1.1.2-rc7
• ui-source Option: Auto
• Underlying Infrastructure (e.g. Baremetal with Dell PowerEdge R630): Baremetal DL360 3 nodes
• Rancher Version: v2.7.2-rc7

Additional context

The root cause is, API(v1/rke-machine-config.cattle.io.harvesterconfigs/fleet-default) PUT method is not work correctly.
