That's because Bacula uses the overall number of known volumes, not 
the number of volumes per pool. This decreases the probability that it 
tries to create a volume which already exists (though it doesn't 
absolutely prevent that).

Just imagine that you delete one volume from the pool - the next one 
automatically created will get an existing name.

In setups where the volume names are expected to be numbered 
sequentially, I just create the volumes manually (or by script, if a 
large number of volumes will be needed).
