Thanks Klaus, After reading Haosdent's response I have a feeling a ticket may already exist: MESOS-3059 which would work for our usecase, however I can't actually access that ticket.
I'm happy to create a new one if needed though?

But I think this reasonable requirement to detect resource on the fly; would you help to open an JIRA for this? I think there're two sub-requirement of this scenario: 1. The resources of slave will be updated on the fly; it's different with MESOS-1739 which focus on agent restart 2. Self-defined resources which is only consumed special resources If any comments, please let me know.

Example: we are dynamically attaching and detaching EBS volumes to EC2 hosts running as agents. (This is part of our docker volume setup using RexRay). When a host has an EBS volume attached to it I'd like to be able to mark that as a new resource on the agent. Note that it's not the disk space we care about here, just the name of the volume itself. This would then allow us to schedule tasks that require access to the data on that EBS volume all on the same host. Anyone have any ideas? Thanks!
