What you are trying to do is not supported by Bacula.  The manual describes a 
way that you can "manually" deal with this situation by splitting the 
bootstrap file into multiple bootstrap files that you then restore.  It is 
not an ideal solution.

The best solution is to follow the example in the manual that shows you how to 
use mutliple pools with the stam storage device.

It is possible that this feature (using multiple devices in the Storage daemon 
during a restore) is implemented in version 1.39, but it is untested and not 
really supported.

Also, if you are using the same MediaType for all your storage devices, you 
will eventually have additional problems.  A given MediaType (as documented) 
implies that the Volume can be mounted on any device with the same MediaType, 
which is clearly not the same if you use different mount points (directories) 
as you have done for your Volumes.
