changing RDGW instance type to t3a.small causes termination #24

Open rosenbluh opened 5 years ago

rosenbluh commented 5 years ago

I attempted to rightsize the RDGW from 8GB since it was using very little RAM. I changed it to a t3a.small and tried to start it. I received a message that the instance type was incompatible, I refreshed and saw that the instance was terminated. The public IP address showed as unassociated.

Is there anything that can be done to address this from the QuickStart? I don't know why this happened, but I think it has happened to me before.

A few ideas in case there is no technical solution or the problem lies with AWS design:

  1. Offer .medium instances and make this the default for RDGWs
  2. Make a note in the documentation, perhaps with a list of other precautions when deploying this quickstart (I am making a list)
  3. Document this in tags noting the compatibility

This is the system log showing only the initial start.

It turns out that a new instance started and got joined to the domain as a new IP and host name. This provided an opportunity to replicate this behavior.

Instance ID i-07fc32b33ff549b76
Instance Type   
 EBS-optimized
An error occurred while trying to change the ebs optimized support of this instance
The instance 'i-07fc32b33ff549b76' is not in the 'stopped' state.

Then I tried changing it to t3a.medium

I found this AWS forum post that was not answered.

I refreshed again and found this instance terminated and another one spun up now on another RDGW spun up but this time on a new public IP address. I guess it picks a public IP address at random rather than trying to use the former IP address attached to the VM.

I would like to know how to rightsize the RDGWs.
