OK, done but i catch some mysterious error...

I've setup a storage device and a pool, the i've tried to run:

 Mount Volume "" on device "FileStorage" (/rpool-backup/bacula) and press return when ready: 

Clearly pool esit and contain the volume:

 *list volume pool=FVG-PP-PPPVE3LTOCopyPool

Seems to me that bacula try to mount the volume 'PPPVE3LTOCopy_0001', fail
in some mysterious way ('because it will be read'), then try to mount the ""
volume.

If i try to mount manually the volume in the device, fail because is a file
device and so:
 *mount storage=PPPVE3File PPPVE3LTOCopy_0001
 3906 File device ""FileStorage" (/rpool-backup/bacula)" is always mounted.


What i'm missing? Thanks.
