Update VSAN Configuration Task failed for ALL 3 ESXI hosts

[raffic_ncc]

I have enabled VSAN on the cluster but Update VSAN configuration task failed with the below error

Operation failed, diagnostics report: Failed to join the host in VSAN cluster (Exec of command '/etc/init.d/vsanvpd restart' succeeded, but returned with non-zero status: 1)

On All the 3 esxi hosts , I can see a warning

Host is in a VSAN enabled cluster but does not have VSAN Service enabled

Please help me to fix this isseu.. I need all the VSAN experts here.. I not finding any troubleshooting solution for this issue.

Hi,

Is your VSAN Network configured properly?

This can happen if the hosts are unable to ping each other over the VSAN Network.

Thanks

Hi raffic_ncc

>> Host is in a VSAN enabled cluster but does not have VSAN Service enabled

VSAN service should be enabled either  on 1G or 10G private network to communicate among VSAN nodes. Once you configure vsan network,  please do check the config with esxclii command 😆  "esxcli vsan network list" command on each node and if you are able to do vmkping among these networks vsan network should get up.

Please find more details about vsan n/w configuration details.

So lets start at the beginning:

• Did you create a VMkernel interface for VSAN traffic on each host?
• Did you enable "VSAN Traffic" on that VMkernel interface?
• Do you have multicast on L2 enabled on your physical switch to which the hosts are connected?

Not sure if this still applies with the GA release, but did you add a license key?

Yes Duncan i did it...

[Deeban]

Also how much is the RAM provided to ESXi?

It should be at least 5GB.

[raffic_ncc]

Minimum requirement is 4 GB..i have allocated 4 GB for each host

[Deeban]

Hi Raffic,

Actually it is 6GB. Please refer the documentation at http://pubs.vmware.com/vsphere-55/index.jsp#com.vmware.vsphere.storage.doc/GUID-CE88B700-26F8-420A-8...

internally we have tested it with 5GB and it works, documented minimum is 6GB.

Thanks Duncan and Deepan....I will increase memory to 5 GB and check

[raffic_ncc]

Duncan...Do we have any official VMware documentation which talks about the ratio of Memory requirement vs No of disks ???

I have not seen this officially documented, but mainly because all "physical" deployments typically will have more than 32GB of memory.

This information was supposed to make it into the VSAN Release Notes, though I have to admit I didn't check that it did.

Here is a post I did on the memory requirements which came into effect for GA.

Thanks Duncan & Comac.....
