Introduction
After you create an edge node cluster, you can manage it. This article explains how to manage edge node cluster instances using the ZEDEDA GUI, including creation, updates, and deletion commands.

View your Edge Node Clusters
After you create edge node clusters, you can view them.
- Select Edge Node Clusters from the left panel.
- Observe the list of your edge node clusters.
- Click an edge node cluster name to view the tabs for items such as: status, identity, edge node details, and storage.
View status
From Edge Node Clusters > CLUSTER_NAME > Status you can see the information, cluster nodes, edge app instances, and network instances.
Information |
Admin status such as:
Run state such as:
|
Cluster Nodes | The list of individual edge nodes that are part of the cluster.
|
Edge App Instances | The list of individual edge app instances that are part of the cluster.
|
Network Instances | The list of individual network instances that are part of the cluster.
|
View identity
From Edge Node Clusters > CLUSTER_NAME > Identity
Id | Identity number of the cluster. |
Name | The name of the cluster. This can’t be changed after you name it. |
Title | The title of the cluster. This is a user-friendly name that can be changed at any time. |
Project | The project that the cluster belongs to. |
Description | The description to help understand the usage or the purpose (or anything) of the cluster. |
Cluster Tags | Tags such as env:production. |
Cluster-Prefix | IP/Subnet mask for the cluster network interface. |
View edge node details
From Edge Node Clusters > CLUSTER_NAME > Edge Node Details
Id | Identity number of the cluster |
Name | The name of the individual edge nodes |
Serial Number | The serial number of the individual edge nodes |
EVE-OS Image Version | EVE-OS image version of the individual edge nodes |
Location | The location of the individual edge nodes |
Edge App Instances Load | The load of the individual edge nodes, such as high or low |
Project | The project that each edge node belongs to |
Network Adapters | A link to expand and show the adapter details |
Drawer | Quick overview or actions for each edge node, so you don’t have to go back to the Edge Nodes menu |
View storage
From Edge Node Clusters > CLUSTER_NAME > Storage
State | State of the cluster volume instances: Creating, Attached, Detached, Attaching, Detaching, Deleting |
Name | The name of each volume instance |
Size | The configured maximum size of the volume instance. |
Actual Size | The current size of the volume instance. Volume instances are thin provisioned and will only consume the size required by the data stored in it. Note that deleting data in the instance will not make the volume shrink. |
Created | The date it was created |
Attachment State | State of attached storage: Bound, Pending, Available, Released, Failed. |
Drawer |

Update an Edge Node Cluster
After you create an edge node cluster, you can update it when things change. You can only perform the update/edit operation in the identity tab.
- Select Edge Node Clusters from the left navigation to list already available cluster instances.
- Click any of the edge node cluster instances in the list view to show the detailed view.
- Click the Identity tab.
- Click the pencil.
- Make your changes to title, tags, or the description.
- Click Submit.
Replace an Edge Node
If an edge node fails (or whatever reason the node needs to be replaced), you can replace it by
- From the left navigation, select Edge Node Clusters > CLUSTER_NAME > Edge Node Details.
- Select the checkbox for the edge node that needs to be replaced.
- Select the ellipsis (...).
- Select Replace.
- Select another Edge Node from the list.
- Select a Network Adapter for the cluster interface, such as eth2 to match your other edge node cluster interface adapters.
- Click Replace.
- Verify the cluster status at Edge Node Clusters > cluster_name > Status.
Add or Delete an Edge Node
Adding or deleting an edge node to or from the cluster is not supported. Only replace is supported.
Delete an Edge Node Cluster
After you create an edge node cluster, you can delete it when you no longer need it. You cannot delete an edge node from a cluster if an application instance, network instance, or volume instance is running on it.
When the edge node cluster is deleted, every node in the cluster will reboot and reconfigure itself to a single node mode.
- Select Edge Node Clusters from the left navigation.
- Click any of the edge node cluster instances in the list view to show the detailed view.
- Click the ellipsis (...) in the top right of the page.
- Select Delete from the dropdown.
- Confirm the deletion.
