SMB access denied. Operation not permitted on {{volumeStyle}} volume. Description: Access Denied: User {{nfsUserName}} tried to '{{nfsOp}}' on a {{volumeStyle}} NAS Volume {{nasContainerIdIntegerName}}, file {{dsidPath}}. [[nl]]Choosing a volume security style dictates which protocol will be used to set permissions on files in this volume. This also sets certain limitations on operations which are not allowed for this security style: [[nl]]1. Setting an ACL for a file in a NAS volume defined with UNIX Security style. [[nl]]2. Setting mode for a file in a NAS volume defined with NTFS Security style. [[nl]]3. Changing the read-only flag for a file in a NAS volume defined with UNIX Security style. [[nl]]4. Setting SID/GSID ownership on UNIX Security style [[nl]]5. Setting UID/GID ownership on NTFS Security style. [[nl]]A user might try to perform one of the above actions and get an 'Access denied' error without understanding why. Action Items: The NAS Volume security style should be chosen according to the main intended usage. If a user needs to perform a security related activity which is forbidden, consider splitting the data into two separate NAS Volumes based on the access pattern.
