> Key: MESOS-8410
> URL: https://issues.apache.org/jira/browse/MESOS-8410
> Project: Mesos
> Issue Type: Bug
> Reporter: James Peach
> Assignee: Benno Evers
> Priority: Blocker
>
> 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:
> {noformat}
> 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
> {noformat}
> The {{--resources}} flag is
> {noformat}
