Error Code error-cluster-network-already-offline — Windows 11

Postup řešení

1. 1 Open Failover Cluster Manager: Press Windows key + R, type 'cluadmin.msc', and press Enter. If prompted by User Account Control, click Yes. This tool is the central console for managing your cluster's networks, nodes, and roles.
2. 2 In the left pane, expand the cluster name and click on 'Networks'. Review the list of cluster networks. Identify the network that is showing as offline. Right-click it and select 'Bring Online' if it is offline, or 'Take Offline' if you intended to change its state. This step directly addresses the error by ensuring the network state matches your intention.
3. 3 If the network is already offline and you need it offline, verify that no cluster resources (like virtual machines or file shares) are dependent on it. In the 'Networks' pane, check the 'Status' column and the 'Cluster Network' details. If resources are dependent, move them to another network or take them offline first.
4. 4 Use PowerShell to check the network state: Open PowerShell as Administrator (right-click Start, select 'Windows Terminal (Admin)'). Run 'Get-ClusterNetwork' to list all networks and their states. Look for the network with State 'Offline'. If you need to bring it online, run 'Start-ClusterNetwork -Name '. Replace with the actual name.
5. 5 If the error persists, check the cluster log for more details. Run 'Get-ClusterLog -Destination C:\temp' in PowerShell to generate a log file. Review the log for any network-related errors that might indicate a deeper issue, such as a network adapter failure or misconfigured DNS.
