Blocker Description
We deployed --reconfiguration_policy="additive" on a number of Mesos agents that had mount disk resources configured, and it looks like the agent confused the size of the mount disk with the size of the work directory resource:
E0106 01:54:15.000123 1310889 slave.cpp:6733] EXIT with status 1: Failed to perform recovery: Configuration change not permitted under 'additive' policy: Value of scalar resource 'disk' decreased from 1830000 to 868000
The --resources flag is
