Verify connectivity, start the supercluster, and confirm its operational status.
Before you begin
Ensure that clusters are joined and reachable.
Follow these steps to verify connectivity and start the supercluster.
Procedure
|
1. |
Use the sedo supercluster connectivity command to verify connectivity between clusters.
Note
Wait until all connections are successful. Clusters typically establish connectivity within 5 minutes.
Example:
sudo sedo supercluster connectivity
┌────────────────────────────────────────────────────────────────┐
│ Supercluster Connectivity │
├───────────────────────┬───────────────────────┬──────┬─────────┤
│ FROM │ TO │ RTT │ RESULT │
├───────────────────────┼───────────────────────┼──────┼─────────┤
│ cluster2/controller-0 │ cluster1/controller-0 │ 14ms │ Success │
│ cluster2/controller-0 │ cluster3/controller-0 │ 15ms │ Success │
│ cluster1/controller-0 │ cluster3/controller-0 │ 12ms │ Success │
│ cluster1/controller-0 │ cluster2/controller-0 │ 12ms │ Success │
│ cluster3/controller-0 │ cluster2/controller-0 │ 13ms │ Success │
│ cluster3/controller-0 │ cluster1/controller-0 │ 13ms │ Success │
└───────────────────────┴───────────────────────┴──────┴─────────┘

2. |
Use the sedo supercluster start command to start the supercluster.
Note
The node where you execute this command becomes the active node. The other worker node becomes the standby node.
Example:
sudo sedo supercluster start
Checking Supercluster connectivity...Passed
Initiating Supercluster...Done

|
3. |
Use the sedo supercluster status to verify the supercluster status.
Example:
This sample output shows the result of the status command on the standby node. When DB replication is streaming and DB Lag is 0 bytes, the geo-redundant deployment is running.
