Move a node
Move a node using OpsCenter Node Administration. Enter a new token to assign to a node. This procedure is not applicable to virtual nodes.
To move a node manually, see the corresponding nodetool move command.
Prerequisites
-
If OpsCenter role-based security is enabled, you must have a role with the Move Cluster Topology permission.
-
See Calculating tokens for single-token architecture nodes to determine the correct token value. The Move menu option is generally used to shift tokens slightly.
Procedure
-
Click cluster name > Nodes.
-
In the List view, select the node.
-
From the Other Actions menu, click Move.
The Move option is also available from the Actions menu in the Node Details dialog.
The Move Node dialog appears.
-
Enter the token in the New Token box.
It is not necessary to escape a negative token value; doing so results in an error: Invalid token. Tokens must be numeric. If the token is out of range, an error message indicates the valid range. Enter a valid token within the given range.
-
Click Move Node.
-
Review the confirmation message. During the move operation, the node isn’t available, which can impact cluster performance.
-
Click Move Node to confirm.
Messages appear in the header to indicate that a move is in progress or completed. Click the Show Details link to view the progress or outcome on the Activities page.
