Nutanix CE installs but CVM does not create cluster in vmware nested environment. | Nutanix Community
Skip to main content

Hi,

I successfully deployed three nodes as VMs in my VMware nested environment without any issues. All are pinging each other. CVMs are also pingable from each other.

But when I create cluster from a CVM, cluster creation failed, medusa and its below listed services are having DOWN status. 

Please help.

What are the specs of the virtual machines and what is the spec for the VMWare server? 

And do you have a screenshot of error? 

Hello!

Please check my article on how to deploy nested CE 2.0: https://en.vmik.net/2023/09/ntnx-ce20-vsphere8-deploy/

 

In short, for each CE VM you need to add advanced parameter disk.EnableUUID = TRUE. Otherwise it can affect Medusa service during cluster creation process.

 

 

Hi,

I created 3 VMs on my ESXi Hypervisor with below configurations:

  1. 4 vCPUs (HW virtualization enabled)
  2. 32 GB memory
  3. SCSI Controller VMware Paravirtual
  4. HDD1- 16GB, thin provisioned, SATA controller 0, used for Hypervisor Boot
  5. HDD2- 200GB, thin provisioned, SATA controller 0, used for Data
  6. HDD3-500GB, thin provisioned, SATA controller 0, used for CVM
  7. disk.EnableUUID to TRUE
  8. 1 VMXNET3 Network Adapter
  9. on vSphere Standard Switch: Promiscous mode=Accept, MAC Address change=Accept, Forged Transmits=Accept

 

Your specs aren't enough (Boot disk is to small). Please follow my tutorial exactly and it will work: https://www.jeroentielen.nl/installing-nutanix-community-edition-ce-on-vmware-esxi-vsphere/

 

 

Hi Jeroen,

Big thanks. With you step-by-step guide, I am able to deploy the cluster.

I was able to login 1st time in Prism Element. Registered for Nutanix NEXT also. Now, I am facing Prism element login issue. Getting Error: Server not reachable. All CVMs are pingable from each other. 1st time login was perfect. 

Please help.

If you just started the cluster then wait a couple of minutes more. If the cluster was running for days try to give a cluster start command in cvm. 

Hi,

I deployed cluster a few days back. While login, throwing an error: server not reachable.

 

 

Why Cluster start process taking too long, It’s taking around 30 minutes or more to start all the services. Is this default behaviour or do I have to make some changes. Please guide.

Thanks.

That depends on the physical hardware. Can take a while to start things up yes. 

I agree with Jeroen. It can depends on the underlying hardware, especially on the disks.

Faced the same on non-nested CE. The simpiest indicator that something goes slow:

Check metadata ring - nodetool -h0 ring - nodes may be in the down state.

Check disks utilization and await time from CVMs: sar -dp or iostat
