Concurrent jobs on same Storage/Device

Hello everyone,

I would like to know if two jobs can write concurrently to the same
(File) Storage/Device.

My issue is that I have two Pools assigned to the same Storage (and
this Storage to its SD Device). When I create a migration job that
moves data from one pool to the other, it waits indefinitely for the
Storage to become available.

The Maximum Concurrent Jobs directive is set everywhere: Director,
Job, Pool, Storage, SD and Device. If I assign a different
Storage/Device to each Pool, the migration job works correctly.

Here is the output of status dir:

Running Jobs:

 68671  Back Full          0         0  my-job           is waiting on

Thank you for your guidance.

Best regards.
