Clustering with the Nutanix Community Edition
The Right Track
Startup and Shutdown
After the install, the cluster is running; however, you might want to shut it down and start it up again later. First, shut down all your workloads and Prism Central. If you are unable to initiate a shutdown from your workload itself, use the Prism Item UI under Home | VM , for example, to change the power state of a VM.
Second, shut down the CVM by going to the CVM's command line and entering:
cvm_shutdown
The CVM shuts down after you are automatically logged off. Third, go to the AHV's CLI and enter:
poweroff
Wait until the NUC has been completely switched off by the system. To start up again, switch on the NUC and wait until you can access the Prism Element UI on https://<IP address of CVM>:9440 . Depending on the hardware, this may take a few minutes.
Conclusions
If you want to set up a cluster without too much overhead, you will find it fairly easy to do with Nutanix Community Edition. This free version is primarily intended for testing the environment and exploring the platform. If you want to deploy the cluster in a production environment, you will need the full version, but both versions of Nutanix are easy to use and flexible.
