CBS Deployment Errors

CBS Deployment failed (due to no outbound internet access)

Symptom:

CBS deployment fails. In the Azure Portal -> CBS managed application -> managed resource group (mrg) -> deployment section, the failure occurs when Azure is deploying the final step called ct0-extension and ct1-extension. If this step takes longer than 10 minutes, there's a good chance it will eventually fail.

The deployment typically takes over 45 mins until it eventually fails.

Azure failure message:

Clicking on th Error details link (as seen above), you will see:

{"code":"DeploymentFailed","message":"At least one resource deployment operation failed. Please list deployment operations for details. Please see https://aka.ms/DeployOperations for usage details.","details":[{"code":"VMExtensionProvisioningTimeout","message":"Provisioning of VM extension cbsnoNAT-ct1-ext has timed out. Extension provisioning has taken too long to complete. The extension last reported \"Plugin enabled\".\r\n\r\nMore information on troubleshooting is available at https://aka.ms/VMExtensionCSELinuxTroubleshoot"}]}

 

Applies to:

All CBS deployments on Azure.

Cause:

When a CBS deployment fails at this stage, it is usually trying to validate the CBS license with Pure1. There are a few possible reasons for failures at this stage:

  • There is no network connection outbound to the internet or Pure1.

Resolution:

Applies to:

All CBS deployments on Azure.

Cause:

When a CBS deployment fails at this stage, it is usually trying to validate the CBS license with Pure1. There are a few possible reasons for failures at this stage:

  • Incorrect license was applied.
  • Customer did not register their Azure Subscription ID with in their Pure1 account.

Resolution:

  • Ensure the correct license is entered during the deployment steps.
  • Make sure the subscription ID is registered with Pure1. See KB article on registering your Azure subscription.

CBS Deployment failed using CLI (due to Term + Conditions)

Symptom:

When deploying using the Azure CLI, the deployment outputs error about accepting terms and conditions.

Azure failure message:

"You have not accepted the legal terms on this subscription"

Full Azure failure message example:

New-AzResourceGroupDeployment : 10:26:28 AM - Resource Microsoft.Solutions/applications 'gsinghtest' failed with message '{
  "error": {
    "code": "ResourcePurchaseValidationFailed",
    "message": "User failed validation to purchase resources. Error message: 'You have not accepted the legal terms on this subscription: '248fd382-1957-464e-87c3-9b0a759516d9' for this plan. Before the subscription can be used, you need to accept the legal terms of the image. To read and accept legal terms, use the Azure CLI commands described at https://go.microsoft.com/fwlink/?linkid=2110637 or the PowerShell commands available at https://go.microsoft.com/fwlink/?linkid=862451. Alternatively, deploying via the Azure portal provides a UI experience for reading and accepting the legal terms. Offer details: publisher='purestorageinc1578960262525' offer = 'cbsdevelopment-preview', sku = 'pazqaplan1', Correlation Id: '5eefd35c-dfc7-4473-b747-1823288e1aa1'.'"
  }
}'

 

Cause:

Before deploying CBS on Azure, user needs to accept the terms and condition. This can be done in the Azure UI portal or via Azure CLI.

Resolution:

Steps to accept terms and conditions for a CBS CLI deployment provided in the CBS Deployment Guide for Azure -> Deploying Cloud Block Store via CLI section

 


CBS Deployment failed (due to Cosmos DB quota limitation)

Symptom:

Cause:

The resources in Azure Cosmos DB have default quotas/limits. However, this might be a case where CBS deployment needs more quota than the default value.

Resolution:

Please follow this link Create Support Quota Request  for how to request quota increase for Azure CosomsDB.


CBS Deployment Failed (due to mismatch in managed application name definition ) 

Symptom: 

Deployment fails even before it gets started. 

image (12).png

Azure failure message:

"The given managed resource group did not match that in the existing appliance definition."

Full Azure failure message example:did not match that in the existing appliance definition

{"code":"DeploymentFailed","message":"At least one resource deployment operation failed. Please list deployment operations for details. Please see https://aka.ms/DeployOperations for usage details.","details":[{"code":"ApplianceManagedResourceGroupMismat85640347bbd1ch","message":"The given managed resource group '/subscriptions/3befd360-cc97-4c57-b412-85640347bbd1/resourceGroups/mrg-pure_storage_cloud_bl-202208' did not match that in the existing appliance definition '/subscriptions/3befd360-cc97-4c57-b412-xxxxxxxxxx/resourceGroups/mrg-pure_storage_cloud_bl-202'."}]} 

Cause: 

A previous failed deployment with the same application name did not got deleted. This causes the mismatch.

Resoution: 

The best way to resolve this issue is by redeploying with different application name. 


CBS Deployment Failed (due to Role Assignment limit exceeded) 

Symptom: 

Deployment failed during roleAssignment creation. 

Azure failure message:

"No more role assignments can be created."

Full Azure failure message example:

{"code":"DeploymentFailed","message":"At least one resource deployment operation failed. Please list deployment operations for details. Please see https://aka.ms/DeployOperations for usage details.","details":[{"code":"RoleAssignmentLimitExceeded","message":"No more role assignments can be created."}]

Cause: 

The number of the available role assignment under the subscription has exceeded the limit. 

Resoution: 

Azure advices to try reduce the number of used role assignment, for more information follow this link Troubleshooting Azure Role Assignment Limit.

To get the number of role assignments, you can view the chart on the Access control (IAM) page in the Azure portal. 


CBS Pre-Deployment Failed (due to offer is not available for subscription from Azure CSP) 

Symptom: 

CBS can not be deployed after selecting Subscription due to the error shown on the Screenshot below. 

clipboard_e6417f8050d166ef2c9077a6382ec6558.png

Azure failure message:

Cannot subscribe to this offer from Microsoft Azure Cloud Solution providers. Either choose a different subscription or contact your Microsoft Azure Cloud Solution provider for more information.

Full Azure failure message example:

Get-AzMarketplaceTerms: Cannot subscribe to this offer from Microsoft Azure Cloud Solution providers. Either choose a different subscription or contact your Microsoft Azure Cloud Solution provider for more information. Offer details:  publisher=‘purestoragemarketplaceadmin’ offer = ‘pure_storage_cloud_block_store_deployment’, name = ‘cbs_azure_6_2_6’. Correlation Id: '9f276c3c-7875-4922-b71f-1a0ad3cebfc5'.

Applies to:

CBS deployments on Azure Subscription have been provided via Azure Cloud Service Provider.

Cause: 

The Azure Cloud Service Provider (CSP) has not been authorized to resell CBS offers on the Marketplace. 

Resolution:

Pure designated Azure alliance and PM have access to the partner portal in order to authorize Azure Service Providers to resell CBS offerings. Please reach out to cbs-response-team@purestorage.com


CBS Deletion Errors

CBS Deletion Failure on Azure

Symptom:

Azure failure message:

Failed to delete managed application "<CBS app name>". Error: Deletion of resource group "<managed resource group name>" failed as resources with identifiers '<Microsoft resource ID>' could not be deleted. The provisioning state of the resource group will be rolled back. The tracking ID is '<tracking ID>'. Please check audit logs for details.

Example: 

clipboard_e9e7667c90ef80461de43160f90d72d29.png

 

Resolution:

1) This is usually an erroneous error. Occasionally Azure will output this error message that one of the CBS resources cannot be deleted. However, given enough time, Azure will eventually delete it and subsequently also delete the whole CBS managed application.

2) If the CBS managed application or underlying resources within the CBS managed resource group does not delete in a timely manner (usually within 10-20 mins), retry the CBS managed application deletion. If it continues to be unsuccessfully, contact Azure Support or Pure Storage Support.
