Ok, then something seems to be wrong with the firstwritten time of this volume.
It's still the date/time when the first differential job was written to
the tape.
*llist volume pool=Differential
mediaid: 5
volumename: 06D124L3
slot: 5
poolid: 5
mediatype: LTO3
firstwritten: 2007-02-24 23:45:04
lastwritten: 2007-04-08 00:12:44
labeldate: 2007-04-08 00:07:08
[...]
This is an example of an old tape from my 1.38.5 server:
*llist volumes pool=Bang
mediaid: 25
volumename: Bang1
slot: 1
poolid: 1
mediatype: AIT-2
firstwritten: 2007-02-18 02:59:10
lastwritten: 2007-02-18 03:12:47
labeldate: 2007-02-18 02:59:10
[snip]
This tape was reused every 2 weeks.

I can't find any message about this in the log file. There are only messages
about pruned files. Nothing about pruned volumes...
11-Apr 00:09 VU0EM005: Pruned Files from 1 Jobs for client VU0EM003 from catalog
This is very differnt from my old 1.38.5 install, where I can find the expected
messages about pruned volumes.
pool config:
Pool {
Name = Differential
Pool Type = Backup
Recycle = yes
AutoPrune = yes
Recycle Oldest Volume = yes
Volume Use Duration = 96 hours
Volume Retention = 31 days
}
double check:
poolid: 5
name: Differential
numvols: 5
maxvols: 0
useonce: 0
usecatalog: 1
acceptanyvolume: 0
volretention: 2,678,400
voluseduration: 345,600
