To create a new cluster network using the Harvester UI, navigate to Networks > Cluster Network Configuration.

Use the Create a Cluster Network option to create the new cluster network. E.g., name it cluznet.

Once the network is created, configure its uplink NIC via the Create Network Configuration option.

To configure the uplink link, a new NIC device must be made available to the Harvester host by performing the following steps using the Linux VMM:

create a new virtual network
use the new virtual network as the source of the NIC

To check the name and version of the harvester-upgrade image, see:

How To Retrieve SSH Key To Harvester Guest Cluster From Rancher UI

Navigate to Cluster Management page on Rancher
Find the Machine Pool section of the cluster
Right-click to access the Download SSH Key option

Changing RKE2 etcd storage size:

echo 'etcd-arg: "quota-backend-bytes=4294967296"' > /etc/rancher/rke2/config.yaml.d/etcd.yaml

Reset RKE2 on Harvester

The rke2 server --cluster-reset command can be used to reset etcd to a single-node cluster, with its data intact.

See https://docs.rke2.io/datastore/backup_restore

Stop the RKE2 server:

sudo systemctl stop rke2-server
