It seems that the manual contradicts itself about this directive, because
http://www.bacula.org/5.0.x-manuals/en/main/main/Configuring_Director.html#SECTION0018150000000000000000
in the same manual defines the Volume Retention directive as:
"The Volume Retention directive defines the length of time that Bacula will
keep records associated with the Volume in the Catalog database after the End
time of each Job written to the Volume."
I.e. it controls pruning, not recycling.
If a Full or Used volume has no jobs in the catalog, then it can be marked as
Purged and can be recycled. AFAICS, the code has worked like that for a long
time and the message
"There are no more Jobs associated with Volume .... Marking it purged."
is printed when it detects that, regardless of the Volume Retention period.
