Overview ¶

Package resvol is the volume resource driver

A volume resource is linked to a volume object named <name> in the namespace of the service.

The volume object contains disk and fs resources configured by the <pool> that created it, so the service doesn't have to embed driver keywords that would prevent the service from being run on another cluster with different capabilities.

Access: * rwo Read Write Once * rwx Read Write Many * roo Read Only Once * rox Read Only Many
