Destroying volume fails saying it's still attached to the machine

[bilby91]

Hello,

We are using fly machines for our coder deployment.

We've been having issue with the destruction of the workspaces. Every time we try to delete the workspace, we run into this issue where the volume can't get deleted because it's still attached to the machine, even though the machine destruction has already successfully completed.

- Reusing previous version of fly-apps/fly from the dependency lock file
- Reusing previous version of coder/coder from the dependency lock file
- Using previously-installed fly-apps/fly v0.0.23
- Using previously-installed coder/coder v0.7.0
Terraform has been successfully initialized!
You may now begin working with Terraform. Try running "terraform plan" to see
any changes that are required for your infrastructure. All Terraform commands
should now work.
If you ever set or change modules or backend configuration for Terraform,
rerun this command to reinitialize your working directory. If you forget, other
commands will detect it and remind you to do so if necessary.

input:3: deleteVolume This volume is attached to a machine(328743d0b43985) and cannot be deleted.

Is there any workaround to avoid having to destroy resources multiple times?

You can find a workaround here: https://github.com/fly-apps/terraform-provider-fly/issues/154#issuecomment-1618942504
