How can a worker (thread) reserve disk space and communicate the reservation with other workers

Question

I am trying to set up an autoscaling class that will check the disk resource to see if a worker can safely run. The disk usage can be estimated prior to running. What are some option for a worker to share this information with other workers?

Answer 1

I think that the best option is to write your own inspect command. See the documentation on how to do that, there's an example at the end of the section.
