 * When configuring the Image Registry Operator to use a private storage endpoint, public network access to the storage account is disabled. Consequently, pulling images from the registry outside of {product-title} only works by setting `disableRedirect: true` in the registry Operator configuration. With redirect enabled, the registry redirects the client to pull images directly from the storage account, which will no longer work due to disabled public network access. For more information, see "Disabling redirect when using a private storage endpoint on Azure".
 
+* Due to a change in storage account naming in {product-title} {product-version}, the Azure File Container Storage Interface (CSI) driver now alphabetically matches storage account of the Image Registry Operator. With this change, there is a known issue where the Azure File CSI driver fails to mount all volumes when the image registry is configured as private. The mount failures occur because the CSI driver tries to use the storage account of the Image Registry Operator, which is not configured to allow connections from worker subnets.

+As a temporary workaround, the image registry should not be configured as private when using the Azure File CSI driver. This is a known issue and will be fixed in a future version of {product-title}. (link:https://issues.redhat.com/browse/OCPBUGS-42308[*OCPBUGS-42308*])

 * This operation cannot be undone by the Image Registry Operator.
