Test the cluster

You can run quick tests to verify that your cluster is operating properly.

Verify successful failover by pausing Redis the primary node, and then checking which node is now the primary.

On the primary node, put Redis to sleep by using the following command syntax:

/opt/aspera/bin/asredis -p redis_port -h node_ip DEBUG sleep num_seconds

For example,

# /opt/aspera/bin/asredis -p 31415 -h 10.11.100.160 DEBUG sleep 30

On one of the other nodes, see which one is now the primary node by using the following command syntax:

/opt/aspera/bin/asredis -p sentinel_port -h node_ip SENTINEL get-master-addr-by-name myprimary_name

For example,

# /opt/aspera/bin/asredis -p 41415 -h 10.11.52.248 SENTINEL get-master-addr-by-name myprimary_name

Verify that replication works across the cluster. First, make a change on one node that adds an entry to the Redis database (for example add a user). Then, verify that it is consistent across the nodes. Finally, remove the change, and verify that it is gone from the cluster.

Create user on one node.

# /opt/aspera/bin/asnodeadmin -au usr2 -p pass2 -x root

From a second node, check that the user was created.
```
# asnodeadmin -l
```
From a third node, remove the user.
```
 /opt/aspera/bin/asnodeadmin -du usr2
```
From the first node, check that the user is gone.
```
# asnodeadmin -l
```
