    Hi everyone,


    I would like to delete on old mount path l but it is attached to the deduplication database.

    There is an windows error ..." The Mount path can be deleted only when all associated storage policies/copies with deduplication enabled are deleted....."

    How could I get around the problem

    Hi GDM,

    you can retire mount paths now -

    • Depending on the retention criteria set on the storage policy copy, the data in the mount path will be pruned when the data aging operation is run.
    • When all the data in the mount path is completely pruned, the mount path can be deleted.

    Library/mount path deletion is blocked if any of the below conditions are true:

    1. DDB is active.
    2. DDB has valid data.
    3. Storage Policies associated with any subclients.

    Hope this helps

    From 11.19, we block deletion only when mount path has any data.

    View contents on mount path may show no valid data but it may contains dedupe data referred by other jobs. so check for physical direcotry contents and see if there is no data then you should be allowed to delete even if DDB is active.


    Before 11.19, you need to seal DDB and wait for all data to be pruned.


    We never block deletion if storage policies associated with subclients.

    Hi GDM,


    if you are sure their is no data being referenced by that path then please open a ticket with support so they can review. There could be some orphande data that may need to be cleaned up.

    they can assist and provide a script to remove if that is the case.

    Hi GDM 

    As mentioned by StorageGuy007, it would be best to engage Commvault Support to verify the findings and if the content of the Mount Path cannot be salvage, there are additional verification steps that needs to be done, before we proceed to delete the Mount Path.

    If after verifying the status with Support and you are still unable to gracefully remove the Mount Path, Support can also share additional method to assist further

    Prasad mentioned in the post above yours that this changed since 11.19.

    You are running 11.18.

    In 11.19 also does not work, I have the same case.
    Version 11.19 plus latest hotfixes was installed on July 6.
    Despite the fact that mountpath no longer contains any data, it is not possible to delete it.
    Same message like from the author of this topic.
    Any suggestion?
    I planned DDB seal tomorrow.
