Volume Use Duration not working as expected

[Brock Palen]

I want to rotate my tapes,. I have copy jobs that copy jobs from disk pools to a tape pool, (leaving one copy on disk and one on tape) and a migrate job that then migrates from disk to longterm pool after a given duration (freeing up disk). I want to use the offsite tape for only 1 month and then rotate out but that’s not happening:

Pool {
Name = Offsite
Pool Type = Backup
Recycle = no
Recycle Pool = Scratch
Auto Prune = yes
Volume Retention = 3 months
Volume Use Duration = 1 months
Storage = Tand-LTO5-Lib
}


I verified with the update command that the volumes in the pool currently have a use duration of 1 month.

1,524 | A00025L5 | Append | 1 | 676,004,797,440 | 252 | 7,776,000 | 0 | 6 | 1 | LTO5 | 2019-07-26 03:18:46 | Tand-LTO5-Lib |

The first job on this volume was 2019-03-15 04:10:34


So why is the volume not marked used so I can eject it and take it off site, leaving just the long term copy local.

I can imagine two things that have happened here:

1. you have not run a job targeting that pool after the tape expired.
AFAIC Maximum Use Duration is only evaluated when looking for a volume
to write to. So if you don't write to the pool no expiry will happen.

2. you changed configuration of the pool without updating the volumes
When you change the pool configuration this will apply to new volumes in
that pool or to volumes moved from the Scratch pool into that pool at
the time they're moved to the pool.
All preexisting volumes must be updated with bconsole's 'update volume'
command. If in doubt use the "update all volumes from all pools" option.
After you have done that, re-evaluate case 1 :)

Extra information:
1. you can look at a volume's details using llist volume=<volname>.

2. the expiration algorithm uses (voluseduration < (firstwritten -
now)), so you can calculate yourself if you want to.

Best Regards,
Andreas
