Unable to change CPU GPU type of a VM

[Vignesh]

Dear all,

I was using a compute engine (VM) with

Configuration 1: T4 GPU and CPU N1-Standard-16 for a high load computation. Later I switched to Configuration 2: no GPU and CPU n2-standard-2. Now, when I intend to revert to Configuration 1: T4 GPU and CPU N1-Standard-16, I get an error "[n2-standard-2, nvidia-tesla-t4] features are not compatible for creating instance." Infact I am unable to change to any configuration.

How do I figure out, what can go wrong and what are things I can do to restore my work. I am lost with this error. What worked 24 hours is no longer working

My project id: sapient-flare-334703

Regards,

Vignesh

This was resolved by first switching to N1-Standard-16, save the instance. Later add 1 GPU to bring to Configuration 1.

I got this clue from https://serverfault.com/questions/985019/can-not-change-hardware-configuration-on-preemptible-gcp-vm

This issue was a googly though.
