My case is that I want multiple jobs to write into the same directory (device) using different volumes. For jobs to be able to write into the same directory concurrently, each one of them has to have separate device, right? > > Maybe it would save some configuration head-ache if it was possible to > specify > > device (as an addition to storage directive) in job's configuration? > > The Storage resource already has a directive to specify a Device. As it's not possible to specify device's direction in job's resource, I have to create a separate storage resource for every device and specify that storage in job's resource, isn't it so?
