Hi All ,

Greetings !!! 
Single node cluster run very good and works like charm .Now i wanted to create an 3 node cluster .
 

LAB Environment:
 

Host Hardware Specs:

  • CPU:

    • Logical Processors: 24

    • Processor: Intel(R) Xeon(R) CPU E5-2640 0 @ 2.50GHz

    • Sockets: 2

    • Cores per Socket: 6

    • Hyperthreading: Enabled

  • Memory: 159.94 GB

  • Hypervisor: VMware vSphere ESXi-8.0U3e-24677879-standard(Free Edition)

  • Setup: 3-node cluster with Nutanix Community Edition

vSwitch Configuration (on all ESXi hosts):

  • Port Group > Security Settings:

    • Promiscuous Mode: Accept

    • MAC Address Changes: Accept

    • Forged Transmits: Accept

VM Configuration (per node):

  • CPU: 8 vCPUs (Hardware Virtualization Enabled)

  • Memory: 36 GB

  • Disks:

    • Disk 1: 128 GB (Thin)

    • Disk 2: 500 GB (Thin)

    • Disk 3: 800 GB (Thin)

  • SCSI Controller: VMware Paravirtual

  • Boot Options: Changed from UEFI to BIOS

  • Advanced VM Configuration:

    • disk.EnableUUID = TRUE

IP Configuration:

Node AHV IP CVM IP
1 192.168.4.94 192.168.4.95
2 192.168.4.96 192.168.4.97
3 192.168.4.98 192.168.4.99

 

  • Cluster IP: 192.168.4.100

  • Subnet: 255.255.255.0

  • Gateway: 192.168.4.1

Installation Status:

  • Installation completed successfully on all 3 nodes.

  • Multiple reboots performed to ensure services started cleanly.

  • Verified genesis status on each CVM:

 

 

$ genesis status Services running on this node: foundation: [4900, 4962, 4963] genesis: [3940, 4126, 4164, 4165]

  • Cluster not yet created:

 

 

$ cluster status CRITICAL MainThread cluster:3241 Cluster is currently unconfigured. Please create the cluster

Issue: Duplicate Ping Responses Between CVMs

  • From CVM on Node 1 (192.168.4.95), when pinging CVM on Node 3 (192.168.4.99):

 

$ ping 192.168.4.99 64 bytes from 192.168.4.99: icmp_seq=11 ttl=64 time=1.53 ms

64 bytes from 192.168.4.99: icmp_seq=11 ttl=64 time=1.53 ms (DUP!)

64 bytes from 192.168.4.99: icmp_seq=11 ttl=64 time=1.53 ms (DUP!)

64 bytes from 192.168.4.99: icmp_seq=11 ttl=64 time=1.53 ms (DUP!)

  • All AHV and CVMs are reachable over the network. Only 1 CVM give (DUP!)

Request:

Please help me 

What could be causing the duplicate ICMP replies between CVMs?
Have I missed any step or misconfigured any setting in ESXi or the VM network setup?

Looking for guidance to resolve this before proceeding to create the cluster.

Thankyou in Advance

Shutdown all CE nodes and ping all ip-addresses. Is there a reply? there you go. 

Turn on 1 node at the time, ping again. Find the root cause. 

There must be something on the network with a duplicated ip.
