      Description

      Hi,

      Yesterday I noticed that TrueNAS is not purging old snapshots. Meanwhile, my NAS is filled with almost 100K of snapshots, which leads to massive storage consumption increase (almost 90% filled).

      During the creation of periodic snapshots, I tweaked a little bit the schedule (every minute, then every 10min, then every 15min), but I didn't rename the schema. I also didn't change the keep interval (2 weeks).

      I don't understand the problem, because normally one would expect that old snapshots would be deleted due to their timestamp. However, it seems that TrueNAS is really depended on the naming schema and scheduler?

      If this error is based on the scheduler,

      Unfortunately, I cannot upload a debug file due to an error (see attachements).
