Requested App Service Plan not available in resource group

Question

Requested App Service Plan not available in resource group

Théo Mouchabac 60

Hello,

I need to update the App Service Plan of one of my web apps to P*MV3.

However I am getting the following error when trying to switch :

Requested features 'Linux Worker, MV3 Series Worker' not available in resource group [...]. Please try using a different resource group or create a new one.

It explains that the resource group does not support this kind of plan but does not explain why.

Where can I find/look for explanation on why the resource group does not support this plan ?

It does not seem that I have reached quotas on this resource group or any other.

Thank you,

Hi Théo,

The underlying webspace (aka Deployment Unit) that your app service plan is in does not support the new size you are requesting. The reason it mentions resource group is webspaces are tied to unique combination of region - resource group - OS. In case you are wondering, moving the app service plan to different resource group will not change the situation.

What you need to do is create new app service plan in new resource group in same region with SKU that you need (e.g. Linux P1mv3). This will make sure the app service plan is placed in webspace that supports P*mv3.

Once you have your new app service plan, create a new app and deploy your existing apps files, copy/paste over any settings as needed, remove binding from old and add binding to new, etc. After your new app is tested and up and running you may consider deleting the old app and app service plan (if the plan is empty).

Scale up from an unsupported resource group and region combination

Note: there is no "Clone App" for Linux

Ok, thank you for the explanation.

Is there also a distinction between PV3 and PMV3 availabilities for a given Deployment Unit? Because my App Service currently is on P2V3.

And I was wondering what the underlying cause for a Deployment Unit supporting or not certain types of plans? Is the one I have too old? (My app was created maybe two years ago).

Too bad I have to do a whole redeployment as the App Service is currently deeply integrated with many other of my services.

Yes. A deployment unit may support PremiumV3 but not MV. These are "newer" sizes, so older DUs may not have (all) of the latest sizes.

Ok clear enough for me! Would be a nice thing to support newer sizes indeed.

Thank you for your reactivity!

This limitation is seriously underdocumented.

It should be mentioned also on all overview documentation because this changes architectural requirements for resource groups.

Hi, I've ran into the same issue. We'd like to keep the same resource group if possible. I found some FAQ here that suggests that deleting all the app service plans, app services, and certificates attached should clear the deployment unit?

This is the docs: https://learn.microsoft.com/en-us/troubleshoot/azure/app-service/create-delete-resources-faq-new#what-if-the-requested-sku-of-the-app-service-plan-isnt-available-in-the-resource-group.

In the docs however, it doesn't mention OS. We have some Windows and some Linux OS apps, and it's the Linux ones we have a problem with. Do you happen to know if we can keep the same resource group if we delete all the Linux apps only and do them again? Thank you!
