The expansion of cluster fails with an error log.
Could anyone tell me how to solve it?
<Detail>
When I try to add a node to a cluster in the prism element,
it fails with the error log below.
Failure in pre expand-cluster tests. Errors: Failed to start foundation service to do network validation SSD tier on nodes ou'xxx.xxx.xxx.xx'] is not sized to accomodate expected metadata growth on cluster. Refer KB-8842 for more details.
<Environment>
As shown in the diagram below, the Nutanix nodes are created
as one of the virtual machines on the ESXi.
used version : ce-2020.09.16.iso
<What I have tried>
・Improving the spec of SSDs in a virtual machine for the additional Nutanix node
SSD1 : 32GB → 64GB
SSD2 : 200GB → 400GB
SSD3 : 500GB → 1TB
・Confirming the result of KB-8842
-->The result of issuing commands are attached as "kb-8842.log"
in the bottom of this page.
<Re-production procedure>
1) Creating Nutanix nodes as one of the virtual machines on ESXi
2) Composing a cluster with 3 nodes
3) Expanding the cluster in the prism fails with the error log
Also, this issue occurs in the procedure below
1) Creating Nutanix nodes as one of the virtual machines on ESXi
2) Composing a cluster with 4 nodes
3) Deleting one node from the cluster
4) Try to add the deleted node to this cluster in the prism
5) This also fails with the same error log
<Background>
I would like to build an environment which enables engineers to test
some functions of Nutanix cluster for promoting sales without configuring every time.
For this purpose, we built the Nutanix nodes as one of the virtual machines
and saved them as templates on ESXi.
From these templates, the Nutanix nodes are supposed to be created, tested and deleted so that engineers can test them easily without configuring.
However, I faced the problem during the verification of this environment. Currently, this environment works except the expansion of the cluster.
It would be appreciated if anyone of you tell me how to solve this issue or advise me to
troubleshoot this problem.
Best regards,
