If they have been reused, there will be no volume to truncate.

It would be nice if you could share the pool resource configuration and a job log reporting no volume available to use. The best approach is to reuse volumes as soon as they have retention expired, but to not keep the pool too tight as it may happen Bacula can't create a new volume or reuse any. Limiting the pool size (in bytes or in number of volumes) and keeping a retention that can fit into this pool size is ideal.
