Hi, is this still an issue? I could help but I might need a bit more details than what you're providing here. For instance, are you using any specific cloud provider? Depending on what you're using there might be different solutions (e.g. a separate volume that can be attached to your VM).
There are also other options besides paying for an actual external volume or increasing your VM size. For example if you're on Azure you can use blobfuse to mount a "storage account container" as if it were a drive. If you're on AWS there's a similar project called s3fs-fuse which pretty much accomplishes the same thing.
