    Description

      steps :

      *) create a mount entry with multiple destinations ( for suppose 2)

      *) Set NS quota as 10 for mount entry by dfsrouteradmin command, Content Summary on the Mount Entry shows NS quota as 20

      *) Create 10 files through router, on creating 11th file , NS Quota Exceeded Exception is coming 

      though the Content Summary showing the NS quota as 20 , we are not able to create 20 files

       

      the problem here is router stores the mount entry's NS quota as 10 , but invokes NS quota on both the name services by set NS quota as 10 , so content summary on mount entry aggregates the content summary of both the name services by making NS quota as 20
