Verify the Running System and Services

After any of the following scenarios, wait 10 minutes for EFA micro-services to be operational before you run EFA commands.
  • Powering on the OVA
  • Rebooting the OVA
  • Rebooting the TPVM
  • Rebooting the SLX (which also reboots the TPVM)
  • Rebooting the server on which the EFA is installed

You can use various commands and scripts to verify the status of the EFA system, to help troubleshoot, and to view details of EFA nodes, PODs, and services.

  1. Verify the K3s installation in a TPVM.
    1. Run the show efa status command from the SLX command prompt. 
      device# show efa status                                                          
       NAME   STATUS   ROLES    AGE     VERSION
	TPVM   Ready    primary   6m59s   v1.14.5-k3s.1
	admin@10.24.51.226's password:
	NAME                            READY  	STATUS    RESTARTS   AGE
	pod/godb-service-wk57h          1/1     	Running  0          6m11s
	pod/gofabric-service-8v8b2      1/1     	Running  3          6m12s
	pod/goinventory-service-4kggf   1/1     	Running  3          6m12s
	pod/gotenant-service-xcqf6      1/1     	Running  3          6m12s
	pod/rabbitmq-0                  1/1     	Running  0          6m12s
	pod/rabbitmq-1                  1/1     	Running   0         4m51s
    Output varies by type of deployment, such as single-node or multi-node, and the services that are installed.
  2. View details of EFA nodes, PODs, and services.
    1. Run the efa status command.

      On a multi-node installation:

      +-----------+---------+--------+---------------+
| Node Name | Role    | Status | IP            |
+-----------+---------+--------+---------------+
| tpvm2     | active  | up     | 10.20.216.242 |
+-----------+---------+--------+---------------+
| tpvm1     | standby | up     | 10.20.216.241 |
+-----------+---------+--------+---------------+
--- Time Elapsed: 4.277420974s ---

      On a single-node installation:

      +-----------+--------+--------+-------------+
| Node Name | Role   | Status | IP          |
+-----------+--------+--------+-------------+
| efa       | active | up     | 10.21.90.43 |
+-----------+--------+--------+-------------+
--- Time Elapsed: 1.461512261s ---
      These examples show only a few of all possible rows of detail.
  3. Verify that all PODs are in a running state.
    1. Run the k3s kubectl get pods -n efa command. 
      # k3s kubectl get pods -n efa

      In a multi-node installation, only the pods on the active node are in "Running" status.
  4. Verify the status of the Authentication service.
    1. Run the systemctl status hostauth.service script. 
      $ systemctl status hostauth.service
hostauth.service - OS Auth Service
Loaded: loaded (/lib/systemd/system/hostauth.service; enabled; vendor preset: enabled)
Active: active (running) since Thu 2020-04-23 07:56:20 UTC; 23 h ago

CGroup: /system.slice/hostauth.service
        23839 /apps/bin/hostauth

  5. Restart a service using the efactl restart-service <service-name> command.
  6. Identify the active node that serves as the database for Kubenetes clusters.
    1. Run the ip addr show command from all nodes.
    2. Verify that on one of the Ethernet interfaces, the virtual IP address shows up as the secondary IP address.
