Today if a web service is attached with a disk, Render doesn't support a graceful shutdown. If I understand correctly, this is because Render wants to prevent 2 services writing to the same disk.

However, for my case, I just need a graceful shutdown. I don't need the zero downtime deployment and don't need a new instance to start before the previous instance completely shutdowns.

I need a graceful shutdown in order to ensure the data isn't corrupted. Killing the service in a sudden manner increases the risk of corrupted data.

Thank you.
