A node removed from the Cassandra cluster has the “live” status in the app listnodes output

Last Updated : Oct 14, 2021 |

Condition

When you remove a node from the cluster, the app listnodes command output indicates that the status of the node removed from the Cassandra cluster is live. You cannot remove this node from the Avaya Aura® Web Gateway cluster using the ./clitool-csa.sh removeClusterNode <node_uuid> command.

Cause

The local Avaya Aura® Web Gateway clock might not be synchronized with the NTP server.

Solution

Procedure

  1. Ensure that the Avaya Aura® Web Gateway clock is synchronized with the NTP server as described in Checking the Chrony service status.
  2. Run the following command to view the node status: 
    app listnodes
  3. Depending on the node status, do one of the following to remove the node:

    • If the node status is down, run the following command:

      ./clitool-csa.sh removeClusterNode <node_uuid>

    • If the node status is live, run the following command:

      ./clitool-csa.sh removeClusterNode <node_uuid> force
  4. Run the app listnodes command and ensure that the Avaya Aura® Web Gateway cluster does not contain the node.
  5. If the cluster still contains the node, contact Avaya support.
