If you’ve created a Custom Engine Version (CEV) for RDS Custom and it gets stuck showing “Creating…”, you’re not alone. This is a common issue that can happen during the setup process. Here’s what you need to know and how to fix it.
This problem happens because sometimes the creation process doesn’t complete properly. The system does generate an event with details about what went wrong, but the stuck CEV may stay in this incomplete state. As a result, you can’t delete or manage it through the usual console or command-line tools.
Several common reasons cause this failure. For instance, the Amazon Machine Image (AMI) and the S3 storage bucket (if you’re using your own media) might not be in the same AWS region. Missing permissions for your Identity and Access Management (IAM) user or role can also block the process. Furthermore, installation files might be missing from the S3 bucket or have incorrect checksums, or you could be trying to use an unsupported SQL Server edition or version. Sometimes, AWS is unable to create the required S3 buckets to store CEV artifacts properly.
When your CEV is stuck like this, regular deletion methods won’t work because AWS still thinks it’s in the middle of being created. To fix this, you will need to contact AWS Support directly. You can’t fix it on your own through normal commands or console actions.
When reaching out to support, be prepared to share some details. Provide the name and version of the CEV, the AWS Region where it’s located, copies of any error messages you’ve seen, and the time you started the creation process. This information will help support staff locate and resolve the issue more quickly.
Once AWS Support intervenes, they can manually remove the stuck CEV from their systems. After that, you can attempt to create the CEV again, making sure to fix any timing or permission issues that may have caused the problem initially.
