      Reddit post, shows bug has existed for a while:

      https://www.reddit.com/r/freenas/comments/an0v8n/periodic_snapshot_tasks_went_missing/

       

      Detatching a pool permanently deletes all associated periodic snapshot tasks.

       

      How to recreate:

       

      1) Have as many Periodic Snapshot Tasks created for pools and datasets.

       

      2) Detach any pool, regardless of number of vdevs or mirror/RaidZ, regardless if SSD, HDD, or external USB.

       

      3) Observe that the Periodic Snapshot Tasks for this recently detached pool are missing.

       

      4) Re-attach the same pool, expecting the Periodic Snapshot Tasks to reload.

       

      5) Instead observe that they do not reappear, as they have been deleted permanently.

       

      * This can also cause issues with snapshots' lifetime, such as "Keep for 3 months" or "Keep for 2 weeks".
