I’ve testing old Nutanix NX box demo with no MA support. The AOS version install is 5.10.6
I tried to create file server using wizard in prism element.
In the last step of wizard when I prompt create the error message showing
Error creating: Invalid CVM subnet configuration, possibly due to incomplete CVM re-ip workflow
I’ve run ncc check and didn’t found subnet mismatch issue.
Please kindly advice how to fix this.

Have you tried with a mathematically valid subnet?
You specified your network as 172.16.1.0 / 255.255.254.0
The network address cannot be x.x.1.0 for this subnet mask. That “1” in your third octet is a 1 in the last bit, 00000001, but that bit is masked in this configuration since your subnet mask is functionally aaaaaaaa.bbbbbbbb.cccccccX.XXXXXXXX (X being the masked bits).
172.16.1.0 can only be the network address of a 255.255.255.0 subnet or smaller.
I recognize correcting this configuration would mean shutting down the cluster and running the IP reconfig script. It also could mean some other adjustments to the network? Not sure what’s going on there.
I wouldn’t be at all surprised if this is why your network validation fails in the creation process.
