After adding additional disk on a VM instance, I got a "Required 'Alpha Access' permission for 'Compute API'" error when clicking save.

enter image description here

Does anybody know what causes this error and how to solve this issue?

  • Did you just added additional disk to your VM and tried to save the changes or did you modified it in some other way too ? The more details you share the better it will be to troubleshoot you issue. – Wojtek_B Aug 06 '20 at 14:56
  • I just used "+ Add new disk" (60GB) to my whole new VM and then saved the changes without doing or modifying anything else. GCP kept showing the same error message (Required...) after I clicked "Save" every time I tried. However, I could manually create a new disk first and then use "+ Attach existing disk" to the same VM instance with no problem. It's weird that I was able to attach an existing (also new) disk but not able to add a new one to the same VM. – Julia Chang Aug 06 '20 at 23:18

    I'm getting the same error all of a sudden, and @JuliaChang's suggestion was the right fix for me. – xrd Aug 07 '20 at 05:24
  • @JuliaChang - did you create this VM "by hand" or it was created by [Deployment Manager](https://cloud.google.com/deployment-manager/docs) as a part of cluster or a group ? – Wojtek_B Aug 07 '20 at 08:00
  • I created the VM through GCP console> Compute Engine> VM Instances> CREATE INSTANCE – Julia Chang Aug 07 '20 at 08:04
  • Can you run `$ gcloud compute instances describe bugdata-node-1` in cloud shell and edit & paste the output of the command into your question ? – Wojtek_B Aug 07 '20 at 08:07
  • There's was a typo in my comment - instead of `bugdata....` there should be `bigdata...` - it's your instance name. You run commands from [Cloud Shell](https://console.cloud.google.com/home/dashboard?cloudshell=true). – Wojtek_B Aug 07 '20 at 08:42
  • You're trying to run the command from the inside if the VM, please run it from [Cloud Shell](https://cloud.google.com/shell). – Wojtek_B Aug 07 '20 at 09:08
  • I attached (not added) the big data-node-1-disk-1 by creating it manually first. – Julia Chang Aug 07 '20 at 09:26

What you're experiencing is a bug. I've found this thread on Google Issuetracker - it looks like Google Engineers already know about it and working on solving it - you can add your email to a CC list or post description of your case there.

If you do this you will be updated as soon as the fix will be rolled out to production.

  • Google has already fixed the bug. I am currently able to add a new disk by editing VM. (no need to create a disk first and then attach it) – Julia Chang Aug 08 '20 at 06:27
