The Distinction
Content
I need permission.
The cluster is created by Proxmox It's an administrator function that changes the cluster configuration, and it's done as an administrator permission account.
Preconditions
Network connections, time syncing, hostname/IP settings, Proxmox I'm going to verify the account permissions.
I'm working on the classified information.
Proxmox Password is the password for screen entry, and the submission document does not contain the source code.
The range of impact
Cluster configuration affects the functions of the dashboard, HA, migration, shared storage.
3.4.1 Cluster situation
Check the cluster name and the configuration node list.
The ID of each node, the online status, the IP address.(LINK) We can see.
3.4.2 Node management
It creates clusters.
3.4.2.1 When a cluster is not formed
If there were no cluster structure, Cluster creation The section is shown.
When the cluster structure is not there, We need a cluster configuration. It's impossible to get along with a message.

It selects the network that is available for inter-node communication, and if you use multiple links, it prepares the same number of networks for all participating nodes.
After the cluster is created, It's a new one. And then you change the cluster configuration.
The cluster joins the three-fourth.
The new node directly adds the functionality to the node that is not yet part of the cluster. VirtOn I'm registered in.
New node connection & address verification Enter the new node IP and port in the region. Bring the badge. Click on the button.
Check the TLS index of the new node to verify that the connected node is correct.
New node API Registering the token Enter the new token ID and token secret created from the new node in the area.
API Tokens require permission to execute a cluster, and they are automatically discarded after the cluster joins successfully.
Token IDs like the current cluster are not available. VirtOn API So you can disconnect, so you use a new node-specific token.
After you check the input, Registering new nodes Click on the button to join the cluster.
After the job is done, the top right hand corner The status is updated. Click the button to check the status of the cluster and the node list again.

How to take action
Failure to create clusters
The cluster name, Proxmox Password, node network
Check the input and check if there's any communication between the nodes.
Cluster Joyn failed to make the cut.
The new node IP/port, the TLS sign, API Token authorization
I'll check the new node access information and the token permissions and then re-register.
Cluster formation after the failure of the visit
Newly arrived, in a quorum, Proxmox API Connecting
If it fails after the new call, check the cluster logs on the dashboard and the alert page.
