Replacing a node
If a node in your cluster is faulty, its status appears as Down in the Status column of the Nodes page, and in the Cluster > Configuration page.
To replace a faulty node:
- Acquire a new node that is identical to the old node, install and configure Redis Enterprise Software on it per the install instructions.
- Add a new node, as described in adding a new node to a cluster.
- Make sure the new node has as much available memory as the faulty node.
- A message appears, informing you that the cluster has a faulty node and that the new node will replace the faulty node.
- If the new node has insufficient memory, you are prompted to add a different node – one with sufficient memory.
