Thanks Ben & John for the quick answers!

The volume in question was a 1.5/3 TB  LTO 5 tape and though they don’t cost 
the world anymore, I’d have hated to
let it go to waste. Anyway, querying the database showed that there was just 
the one single job that failed assigned to it,
so deleting that job and marking it purged should hopefully have done the 
trick. It’s now residing in the scratch pool waiting
to be used, so I’ll know as soon as one of the other pools are full…

Thanks again!
