Azure VM provisioning / resizing not working

Question

We have subscription and in which we have 6 Virtual Machines. I am not able to resize the VM or procure VM even though I have significantly more quota.

I thought, it may be temporary issue. But , it seems it is persistent.

Automated troubleshooting solution is not helping to decide next steps.

What needs to be done ?

Answer 1

If you are experiencing issues with resizing your Azure Virtual Machines (VMs) or provisioning new VMs despite having sufficient quota, it is likely due to allocation failures. Here are some steps you can take to troubleshoot and resolve the issue:

1. Check Resource Availability: The cluster or region where you are trying to resize or create the VM may not have sufficient resources available for the requested VM size. You can try resizing to a smaller VM size that may have more availability.
2. Stop All VMs in the Availability Set: If your VMs are part of an availability set, stop all VMs in that set. This can help in reallocating resources across the clusters. After stopping, attempt to resize the desired VM.
   • Navigate to Resource groups > your resource group > Resources > your availability set > Virtual Machines > your virtual machine > Stop.
   • After all VMs are stopped, try resizing the VM again.
3. Retry the Allocation: Sometimes, allocation issues can be temporary. Waiting for a short period and then retrying the allocation can resolve the problem.
4. Consider Changing Regions or Zones: If the current region or zone is experiencing high demand, consider deploying or migrating your VMs to a different region or availability zone where there might be more capacity.
5. Use Azure Support: If these steps do not resolve the issue, consider reaching out to Azure Support for further assistance. You can submit a support request through the Azure portal.

By following these steps, you should be able to address the provisioning or resizing issues with your Azure VMs.

Hey Vineet!

It looks like you’re encountering some persistent issues with resizing or provisioning your Azure Virtual Machines, even though you have enough quota. Here are some steps and considerations that might help you troubleshoot and hopefully resolve the issue:

1. Check Regional Availability: Ensure the VM size you are trying to use is available in the region where your existing VM is deployed. You can check this by going to your VM in the Azure portal, selecting 'Size' under the 'Settings' section, and seeing the list of available sizes.
2. Confirm VM Series Compatibility: Different VM series have compatibility requirements. Make sure the VM size you are trying to resize to is compatible with the VM series you are currently using.
3. Resource Group Quotas: Sometimes, even if it seems you have enough quota, there could be implicit limitations. Check your resource quotas in the Azure portal by navigating to 'Resource groups', selecting your resource group, and reviewing the 'Quotas' section. If you find yourself at the limit, consider requesting a quota increase.
4. Consider Alternative Sizes: If your desired size is not available, you might want to select an alternative size that is available in your region.
5. Check for Allocation Failures: If you are seeing allocation failures, this can be caused by the cluster not having enough capacity for the requested VM size. Consider stopping (deallocating) all VMs in the availability set to release resources before starting them again.
6. Diagnose Further: Use the Azure portal to collect activity logs, which can provide insights into what may be causing the problem.
7. Region Migration: If the desired VM size is crucial for your workload and it’s not available in your current region, consider migrating your resources to a different region where the VM size is available.

If none of these steps resolve your issue, I recommend reaching out to Azure support directly for a more in-depth investigation, as they have access to tools and logs that we don't.

Follow-Up Questions:

1. Have you checked the availability of the desired VM size in your region?
2. Are you encountering any specific error messages when attempting to resize or provision the VM?
3. Can you confirm if all VMs are currently running or if some have been stopped?
4. Have you accessed the quotas section in the Azure portal to verify your usage?
5. Are you using an availability set for your VMs, and if so, what happens if you stop those VMs and try again?

Hope this helps you get back on track! Feel free to ask if you need more assistance!
