Could you please tell me how exactly can I change the default btrfs file system to overlay on Concourse as a bosh deployment? I have searched for details about that procedure but I could not find more information about the exact procedure. I can see people that have done this in Concourse but they don’t talk about the details of the procedure that they have done in order to achieve this switch. What we have done so far is the following:
- We have set the property for the storage driver of the baggage claim to have a value “overlay”.
- We have redeployed the Concourse dosh deployment.
However after the Concourse redeployment the worker nodes of Concourse still have the btrfs type for the file system for baggageclaim.
Note: Currently our VM Update Strategy is changed from the default delete-create to the new create-swap-delete vm replacement strategy as described here https://bosh.io/docs/changing-deployment-vm-strategy/
I am not sure if this strategy affects the storages and if it will delete the old ones and create the new ones with the right file system, so we had an idea to switch back to the old vm replacement strategy - create-delete and to redeploy the Concourse bosh deployment again.
Can you please help us to switch from btrfs to overlay? What are we missing?
