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 Redise Pack on it per the install instructions.
Note: If you are using Redise Flash, you must make sure the required flash storage is set up on this new node.
- Add a new node, as described in Joining 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.
Note: If there is a faulty node in the cluster to which you are adding a node, RP will enforce using the new node to replace the faulty one.
Note: The DNS records must be updated each time a node is added or replaced. For additional details, For more information, refer to DNS.
