Hi there,
With a single drive and staff manually inserting tapes each morning, PBS pre-selects a next-media-label and strictly demands that exact tape, even with --force-media-set and allocation policy Always:
The staff inserts whichever tape is scheduled for that day – they cannot predict or control which tape PBS will select from the pool in advance.
Workaround we implemented: We read proxmox-tape backup-job list --output-format json every 5 minutes and display the next-media-label prominently in a custom web dashboard, so staff knows which tape to insert. This works, but feels like it should be unnecessary.
Feature request / question: Is there a way to tell PBS "use whatever tape is currently in the drive" without pre-allocating? Something like a --use-current-media flag would be very helpful for single-drive manual rotation scenarios.
Environment:
PBS: HPE ML350 Gen10
Drive: HP Ultrium 6-SCSI (/dev/st0), no changer
Pool allocation: Always
Retention: 12h
Use case: daily offsite rotation, staff swaps tape each morning
Both issues make proxmox-tape backup with --groups filtering on a changer-less drive essentially unusable from the CLI. Happy to provide logs or test patches.

wrong media label LTO6-Dienstag1 (uuid...)
Please insert media 'LTO6-Montag1' into drive 'LTO6'The staff inserts whichever tape is scheduled for that day – they cannot predict or control which tape PBS will select from the pool in advance.
