    what's the best way to delete a data path thas deduplication enabled?

    when going to the global dedupe policy and selecting a data path to be removed, i get a warning that says "Deletion of a disk data path is not allowed since the copy has deduplication enabled."

    I really don't have any contents on that data path.

    thanks in advanced!

    Hello advntracer,

    What version of Simpana are you using, also is there physical data on the library path (from the OS level)?

    Hi There,

     

    In a dedupe scenario it's possible your mount path contains data that we are still deduping against, years later, even if the retention is only a couple of weeks. The reason for this is because we never delete unique data until there are ZERO references to it against other jobs. This is also why sometimes you see no jobs against the mount path when you right click 'view jobs'. Technically the 'jobs' are gone, but there will still be data which is required by other jobs and spread out across other mount paths. 

    You cannot decommission any mount path from a library that has deduped data on it until the deduplication store has been sealed, the mount path disabled for write, and the FULL retention period elapsed for those jobs pertaining to the old store. Another way of saying this is, as soon as you introduce a mount path into a dedupe library that path becomes part of a whole and cannot be removed until the dedupe store is a) no longer active and b) all jobs against the store have aged. 

     

    The best course of action would be to log a case with CV Support to check your environment and provide guidance on how to best move forward. (there are a few things to take into account and it's not always possible to cover every scenario with a forum post) : ) 

     

    All the best.
