=> I don't thinky you screwed up anything... the problem is that Bacula
=> does not look ahead in time during a 'sta dir' command. Most of the
=> time, the "*unknown*" volume display is caused by having no volumes
=> available at the time of the display, but later, volumes might get
=> recycled.

=> By the way: Given that Bacula works with an implicit "Accept Any
=> Volume" setting anyway, the exact volume to be used is only partly
=> interesting. Having the pool which will be used displayed would, in
=> many cases, be more informative.
I agree.
Here's my solution to the question:
I run a script (after the nightly catalog backup) to produce a report of:
what tapes are in the changer that are in need of replacement
what tapes are available for reuse
what backups are scheduled for the next day
estimates of the size of the upcoming backups,
how many volumes will be required, and how many
volumes are available in the changer in the
specificed pool and the Scratch pool
I've attached the "dailyreport" script, which depends on the
"bacula_pool_report" script (also attached). The "dailyreport" script also
depends on two SQL queries. These could be embedded in the script, but since I
call the queries manually as well, they are in my "query.sql" file. In my case,
they happen to be numbered queries 18 & 24 (and those numbers are hard-coded
into the "dailyreport" script). The queries are:
########################################
# 18
:List Volumes in the changer that are in need of replacement
SELECT VolumeName As VolName,Storage.Name AS Storage,Slot,Pool.Name AS
Pool,MediaType,VolStatus AS
Status, VolErrors AS Errors
FROM Media,Pool,Storage
WHERE Media.PoolId=Pool.PoolId
AND Slot>0 AND InChanger=1
AND Media.StorageId=Storage.StorageId
AND ( (VolErrors>0) OR (VolStatus='Error') OR
(VolStatus='Disabled') OR (VolStatus='Full'))
ORDER BY Slot ASC, VolumeName;
###############################################################
# 24
:Find next volumes to load
SELECT VolumeName AS VolName,Pool.Name AS Pool,MediaType AS Type,VolStatus AS
Status, InChanger
FROM Media,Pool,Storage
WHERE Media.PoolId=Pool.PoolId
AND InChanger=0
AND Media.StorageId=Storage.StorageId
AND ( VolStatus IN ('Purged', 'Recycle') OR Pool.Name='Scratch')
ORDER BY VolumeName;
