    check 

    crcontrol --queueinfo

    crcontrol --dsstat

    Probably below tech notes will help you to find it

    Use case 3: Data protected with a PureDisk client and stored on a PureDisk Storage Pool.
    1. The data removal policies, which run at a user's scheduled time, automatically dereference the affected files in the MetaBase Engine (catalog) and add the necessary expiration transactions in the Content Router (CR) queue for removal.
    2. Transactions in the queue are processed by the Queue Processing Policy, and the corresponding data pointers are dereferenced from storage. The schedule of the Queue Processing is 2 times a day by default; it can be changed from the PureDisk WebUI.
    3. On a monthly basis a CR garbage collection policy runs automatically to clean up any orphaned data, which can occur in certain edge cases. If you have very short retention policies (retention of less than 5 days), then it is useful to schedule CR Garbage Collection more frequently (once or twice a week).

    hi ,

    there will be a schedule clean which will recalim the space from the expired images...there is nothing manully we need to do unless there is a issue with the schedule clean or you can not wait till next schedule run.

    you will have option to run the manual clean in those cases.. but do rememeber it should not be a regular practice.

    follow the below T/N to see how to reclaim manually.

    i have to add, the hd space is slowing getting less and less so if there's an already scheduled clean policy it seems it's not working.

    quite complex. from what i gathered from the above links, garbage collection is already happening in the background. maybe we just use space to aggressively to notice the space reclaimed.
