Hope this is the right place to ask this - if not, sorry.

Using 2.4.4, automatic recycling doesn't allow tapes to be reused.

I've discovered that if I set the tape status to "recycle" then when the
next scheduled job runs it recycles the volume - all data lost (good)
then announces that the max use duration is (already!) exeeded, and
marks the tape as "used"

27-May 00:03 machine-dir JobId 191: Start Backup JobId 191,
Job=testbackup.2009-05-27_00.03.31.06

27-May 00:03 machine-dir JobId 191: Using Device "DDS-4"

27-May 00:04 machine-sd JobId 191: Recycled volume "Scratch_1" on device
"DDS-4" (/dev/nst1), all previous data lost.

27-May 00:04 machine-dir JobId 191: Max configured use duration
exceeded. Marking Volume "Scratch_1" as Used.



...but continues to complete the job. Then the next night, the tape's
marked as "used" and the backup fails.
The "lastWritten" shows the last written time correctly; LabelDate shows
the time the volume was recycled; but firstwritten shows the time & date
the tape was first used. Not sure if that's how it's meant to be, but in
order to use my tapes I have to set UseDuration to be more than the time
since firstwritten and now.

So if I want to use this tape until Friday, for example, I have to set
UseDuration to be 54 days. Then when I come to reuse the tape in 4
weeks' time, I'll need to manually change the UseDuration to be 72 days
(54+28)

Shouldn't recycling reset the firstwritten time? Or should it calculate
UseDuration from something else? Am I expecting something too much?
