怎么在linux用cifs格式的文件

declare

linux上装了oracle，还通过cifs连了windows比较大的存储；因为linux本身空间不够，oracle需要别的空间创建data files；发现oracle无法在cifs格式的文件系统上创建data files；
           现在希望使用openfiler来把cifs转换成iscsi格式的，只是原来没有用过openfiler，想问这种方法可行吗？openfiler是装在linux还是windows上？

openfiler是linux的,本身就需要安装在机器上,是定制的linux版本

可以直接用windows的nfs协议

Implementing and configuring NFS on Windows Server 2003 R2

Tech Note #5 in the "Interop Components in Windows" series                     
By Rodney Ruddock (Interop Systems)


Overview
With Windows Server 2003 R2 several of the components that were previously part of Windows Services for UNIX (SFU) became part of the base operating system distribution. This includes the Network File System (NFS) components. There have been changes to these components since the release of SFU version 3.5.

With Windows Server2003 R2 the NFS components no longer contain support for PCNFS and Gateway for NFS. The resource overhead with Gateway for NFS was fairly high and it was deemed much better for the client machines to connect as full NFS clients. The gained speed and lower resource use with NFS Client make this decision very clear. Since more Windows systems are able to run full NFS Clients rather than PCNFS, a similar decision was made for PCNFS support.

There is also new functionality added that will continue to be used in future Windows Server releases. One of these new bits of functionality is the addition of Unix user ID information within Active Directory (AD). Based on RFC 2307 this information can be used by NFS clients and servers for correctly mapping Windows IDs to and from UNIX IDs. It can be used for NIS support as well. The Username Mapping (UNM) available with SFU continues to be available with Windows Server 2003 R2 to support IT sites as they transition to using the new AD functionality. It should be noted that starting with Windows Server 2008 (Longhorn) UNM will no longer be supported.

These changes mean that administrators need to do some planning for the longer term to be prepared for later releases of Windows Server. Server 2003 R2 can be viewed as a “transition release” because UNM and RFC 2307 in AD are supported. The planning involves not only servers, but also clients. Client machines running NFS Client from SFU 3.5 are capable of using UNM, but cannot use the newer 2307/AD capability for ID mapping. This applies to any Windows client release prior to Windows Vista, e.g. Windows XP. Windows Vista comes with NFS Client capabilities that can use both UNM and 2307/AD functionality. Windows Server 2003 R2 is thus capable of supporting both the old UNM and the newer 2307/AD ID mapping. But from Server 2008 and onward the client machines will need to be Windows Vista as a minimum.

Selecting Component Installation
The first of several tasks is to install all of the needed components (NFS Server and any supporting components). Which supporting components you will need depends on what support is required for the NFS Client machines in particular.

If your client systems are releases of Windows prior to Windows Vista then you will need to use UNM. Those earlier systems will be running SFU 3.5’s NFS Client which only works with UNM.

If you have a completely new array of just Windows Vista machines then the recommendation is to use the newer RFC 2307 functionality in AD. The will mean fewer changes and transitions in your next upgrade cycle.

For definition purposes here is a brief explanation of what identity mapping is and why it is required. Modern Windows systems have unique identifiers for users and groups; these identifiers are different than with Unix systems. Unix UIDs and GIDs are only guaranteed to be unique on a per machine basis. A global management system, such as LDAP or NIS, can be used by Unix machines to enact a network-wide regime. In contrast the Windows identifiers are virtually unique amongst all Windows systems with the use of a SID (Security IDentifier). A SID and a UID/GID naturally do not match.

To create common ground for identification between the two systems, identity management on Microsoft Windows has been extended to provide UIDs and GIDs for users and groups respectively. Initially with SFU an implementation of NIS in conjunction with a User Name Mapping server allowed for the common ground between Windows and Unix systems. Starting with Windows Server 2003 R2 and continuing with Windows Server 2008 the information to map SIDs to UIDs and GIDs becomes part of AD’s implementation of RFC 2307.

With a Unix UID and GID stored in either or both UNM and AD on a per user basis, an easy mapping between Windows SIDs and Unix UIDs/GIDs is achievable. Now a Windows computer and a Unix computer can communicate user identification using common credentials. This leads to NFS communications between Windows and Unix computers.

Installing NFS Server and friends
Note: It is assumed that you have already installed Active Directory and DNS with the correct configuration.

Open the Control Panel and then start the Add/Remove Programs utility. After it has started select from the left panel “Add/Remove Windows Components.”
