When a secret's usage is specified, for example: <secret ephemeral='no' private='no'> <uuid>540c56d1-f4b3-5031-b76d-33e99e9b5c64</uuid> <usage type='volume'> <volume>/tmp/test</volume> </usage> </secret> If another volume '/tmp/test1' isn't used, the current secret's usage can bo modified to '/tmp/test1'. If '/tmp/test1' has been used for another secret, error message will be outputed.
