Abstract

在服务器系统中提供高可用性的系统和方法，包括计算机程序产品。在一种实现中，服务器系统是两个或多个自主服务器节点的集群，每个运行一个或多个虚拟服务器。节点出故障时，将其虚拟服务器迁移到一个或多个其他节点上。节点和客户机间的连接性基于虚拟IP地址，其中每个虚拟服务器具有一个或多个虚拟IP地址。虚拟服务器能被指定故障转移优先级，并在故障转移中可在较低优先级服务器前迁移较高优先级的虚拟服务器。通过将虚拟服务器从故障节点分配到多个不同节点，能提供负载平衡。当节点中的端口出故障时，节点能将虚拟IP地址从故障节点重新分配给节点上的其他端口直到不存在好的端口为止，仅在此时才将虚拟服务器迁移到另一节点或多个节点。

Description

高可用性集群虚拟服务器系统
技术领域
本发明涉及俗称为文件服务器的高可用性文件服务器系统。
背景技术
高可用性服务器系统是即使在系统硬件或软件故障后，也能继续运行的系统。提供高可用性的通用方法是使系统部件加倍。如果一些部件不可用，可以使用另一个代替。强壮的高可用性系统不具有单点故障。单点故障是其故障致使系统不可用的部件。高可用性文件服务器系统通常由两个或多个服务器(节点)的集群(cluster)构成。集群的节点具有它们自身与客户端间的网络连接，并且每个节点直接或间接连接到一个或多个磁盘存储单元。
高可用性实现能基于共享磁盘模型或非共享磁盘模型。在共享磁盘模型中，由集群节点同时共享数据，并且锁定管理器用于访问控制。在非共享磁盘模型中，共享数据访问；但是随时地，由一个节点永久地拥有每个磁盘卷。共享磁盘模型是最通用的方法。当未共享磁盘时，必须在两个未共享磁盘集间复制数据，这增加了一些风险和复杂性。
高可用性系统中的节点通常由一个或多个指令处理器(通常称为CPUs)、磁盘、存储器、电源、主板、扩展插槽以及接口板组成。在主从设计中，系统集群的一个节点被称为主要或主服务器，以及其他节点被称为辅助、接管或从服务器。主要和辅助节点具有相似的硬件，运行相同的操作系统，具有所安装的相同的补丁，支持相同的二进制可执行程序以及具有相同或非常相似的结构。主要和辅助节点均连接到相同的网络，通过该网络，它们彼此通信以及与客户端通信。两种节点运行兼容的故障转移(failover)软件版本。在一些结构中，除共享磁盘外，每个节点具有它自己的专用磁盘。专用磁盘通常包含引导信息、操作系统、联网软件以及故障转移软件。在一些实现中，专用磁盘是镜像的，或提供冗余磁盘。
系统节点不断地彼此监视以便每个节点知道另一个的状态。这种监视能使用称为心跳网络(heartbeat network)的通信链路来实现。能在任一可靠连接上实现心跳网络。在许多实现中，心跳是基于以太网连接。心跳网络还能使用诸如运行串行协议的串行线路之类的来实现，串行协议诸如PPP(点对点协议)或SLIP(串行线因特网协议)。还能通过共享磁盘提供心跳，其中磁盘、或磁盘片专用于基于磁盘的心跳的交换。当心跳停止时，服务器了解心跳伙伴的故障。为避免单点故障，可实现多个心跳网络。一些实现在专用网络(即仅用于心跳通信的网络)上运行心跳，其他的则在公用网络上运行心跳。当心跳停止时，在续存的(surviving)节点上运行的故障转移软件能使自动故障转移透明地发生。
在故障转移后，健康节点(healthy node)可以访问与故障节点访问的相同的数据并提供相同的服务。这是通过使健康节点采用与故障节点相同的网络身份以及准许健康节点访问共享磁盘中的数据同时切断(lock out)故障节点来实现的。
NIC(网络接口卡)有时出故障。一些高可用性系统通过提供备用NIC，具有冗余的网络连接性。NIC能具有一个或多个网络端口。在网络端口出故障的情况下，由故障网络端口提供的网络服务被迁移到备用端口。在这种情况下，不需要故障转移到另一节点。能为公用和专用心跳网络提供冗余网络连接性。
一些高可用性系统支持虚拟网络接口，其中，将多个IP(因特网协议)指定到相同的物理端口。服务与网络身份(虚拟网络接口)和文件系统(存储器)关联。节点(物理服务器)中的硬件提供网络连接和文件服务器所需的计算资源。虚拟IP地址不将客户端与特定的物理服务器连接，其将客户端与在特定物理服务器上运行的特定的服务连接。磁盘和存储设备不与特定物理服务器关联。它们与文件服务器关联。当在节点中有故障时，虚拟网络接口和文件系统被迁移到健康节点。因为这些服务不与物理服务器关联，关于哪个物理服务器提供服务，对客户端来说无关紧要。当设置虚拟IP地址或将虚拟IP地址从一个物理端口移动到另一个时，生成免费ARP(地址解析协议)包。这允许客户端、集线器以及交换机更新它们的高速缓存中的MAC(媒体访问控制)地址，该地址对应于虚拟IP地址的位置。
所有故障转移导致一些客户端中断。在一些情况下，在完成故障转移后，系统具有比故障转移前更低的性能。当健康节点除提供它自己的服务外，还负责提供由故障节点提供的服务时，会发生这种情形。
发明内容
一般来说，在一个方面，本发明提供具有两个或多个自主服务器(autonomous server)(称为节点或物理服务器、连接到存储设备)的集群的高可用性集群服务器系统以及计算机程序产品和用于操作这些系统的方法。节点之一是主节点以及其余的为从节点。每个节点运行一个或多个虚拟服务器。虚拟服务器由网络资源和文件系统组成。当一个节点失败时，透明地将其虚拟服务器传送到一个或多个其他节点。这是通过提供两组无缝连接性来实现的。第一组位于节点和客户端之间。第二组位于节点和存储系统之间。第一连接性基于客户端和节点间的虚拟IP技术。第二连接性-后端(backend)连接性-能使用光纤信道、SCSI(小型计算机系统接口)、iSCSI(IP上的小型计算机系统接口)、InfiniBandTM体系结构或任何其他这些技术，或使用它们的组合来实现。
节点通过心跳网络彼此通信以便确定彼此的健康状况。心跳能在IP或SAN(存储区网络)基础结构，或在两者上操作以便确定节点的可用性。如果节点之一或其部件之一出故障以致在那个节点上运行的虚拟服务器失败，发生故障转移。
在故障转移中，使故障节点的虚拟服务器迁移到另一节点上。在某些故障条件下，无缝连接性和冗余硬件和软件部件允许继续访问文件系统而不调用故障转移过程。能为虚拟服务器指定优先级，并且在故障转移后，能在较低优先级虚拟服务器之前调用(bring up)较高优先级虚拟服务器。能通过将虚拟服务器从故障节点分配到多个不同节点来提供负载平衡。
一般来说，在另一个方面中，本发明提供系统、程序和方法，其中多个虚拟服务器驻留在单个物理服务器上。每个虚拟服务器独占拥有一个或多个文件系统以及一个或多个虚拟IP地址，并且它看不到其它虚拟服务器独占拥有的资源。将虚拟服务器管理为单独的实体并且它们共享物理服务器上的物理资源。
一般来说，在另一方面中，本发明提供系统、程序和方法，其中，能可选地不从故障节点迁移不重要的服务。能通过管理器配置来完成设置虚拟服务器的优先极以及防止迁移不重要的虚拟服务器。
一般来说，在另一方面中，本发明提供系统、程序和方法，其中监视节点的加载以便识别加载比其他节点少的节点。使用这一信息来执行负载平衡。在故障转移后，优先于负载较重的节点，将虚拟服务器迁移到负载少的节点。因为节点能支持多个虚拟服务器，即使在没有故障时，在正常操作期间，也能用这种方法实现负载平衡。
一般来说，在另一方面中，本发明提供系统、程序和方法，其中，为最小化出现故障转移，每个节点在单个子网或不同子网内具有多个网络端口。(子网是通过提供具有相同前缀的IP地址，共享共用地址部件的网络的一部分)。如果端口之一失败，将服务移动到一个续存的端口。这允许多个网络端口故障发生而不调用故障转移，以便仅当没有续存的端口时才出现故障转移。
本发明的实现能实现一个或多个下述优点。故障转移仅用作最后一个手段，因此限制由故障转移引起的对服务的可访问性的中断。通过负载平衡，提高总的系统性能。当出现故障时，通过可选消除低优先级服务来提高总的系统性能。
在下述附图和说明书中阐述了本发明的一个或多个实现的细节。从说明书、附图和权利要求书，本发明的其他特征和优点将变得显而易见。

具体实施方式
图1示例说明根据本发明的高可用性服务器的部件。服务器具有节点集群，节点A 101、节点B 102、...、节点J 103。每个节点具有一个或多个虚拟服务器。节点A具有标记为VSA1、VAS2、...VSAn1的n1个虚拟服务器。节点B具有标记为VSB1、VSB2、...VSBn2的n2个虚拟服务器。节点J具有n3个虚拟服务器，标记为VSJ1、VSJ2、...、VSJn3。每个节点通过存储网络110连接到一个或多个存储系统。服务器具有多个存储系统121、122、123。如图1所示，每个虚拟服务器拥有一个或多个文件系统121a、121b、121c、122a、122b、122c、123a、123b和123c。有一个可由所有节点访问的共享磁盘124。该共享磁盘被称为涂写磁盘(scribble disk)；它包含状态和配置数据。该存储网络110能是光纤信道、SCSI、iSCSI、InfiniBand或任何其他这种技术。客户端105、106和107通过一个或多个网络104，诸如网络1、网络2、...、网络N连接到节点上。每个节点具有至少一个物理端口，并且多个虚拟地址能驻留在相同的物理端口上。RAID存储接口112向所有节点提供逻辑卷支持。每个逻辑卷能由多个磁盘组成-例如，在RAID 0、1、5、1+0或5+0配置中。
虚拟服务器拥有不包括其他虚拟服务器在内的文件系统和虚拟IP地址。它们共享物理服务器上的其他物理资源。虚拟服务器不能看见由其他虚拟服务器独有的资源，并且作为单独的实体被管理。使用虚拟服务器来集合资源(虚拟IP地址和文件系统)便于在故障转移期间移动资源并且比单独处理每个资源更有效。
每个节点能具有多个网络端口，也称为物理IP端口(PIP)。如果一个端口失败，节点将恢复，只要在该节点上有健康的网络端口。节点上最后一个端口故障导致故障转移到健康的节点。
集群中的节点能充当主或从节点。仅有一个主节点，其余节点是从节点(或者处于转移状态，例如均不是)。主节点协调从节点的活动。从节点向主节点报告它们控制的资源。从服务器仅知道它们自己的资源和状态。主服务器维持用于整个集群的状态信息。还维持在负载平衡期间使用的有关服务器负载的信息，其中系统试图在健康节点中大约平均地划分它的工作。
在正常操作期间，每个节点测量它的CPU使用率以及它的IOPS(“每秒的I/O操作”)的总量。IOPS的数量表示当由客户端访问时，节点上的总负载。通过共享磁盘或网络，将这一信息传送到主服务器。当特定节点上CPU利用率和/或IOPS上的数量超出阈值时，主节点将检查其他节点上的负载。如果在系统中有能处理更多工作的节点，主节点将一些虚拟服务器迁移到它们上。目的是在健康节点中或多或少平均地划分工作。用于触发负载平衡的CPU和/或IOPS负载的阈值是能通过系统的管理接口控制的可配置参数。
在相同节点中，能通过在健康网络端口中重新分配虚拟接口来可选地执行网络端口上的负载平衡。节点中的软件监视节点的物理端口上的负载。如果一个端口实际上处理比其他端口更多的网络通信量，将它的一些虚拟接口移动到不太忙的端口中。选择移动哪一个虚拟接口或哪些虚拟接口能基于每个虚拟接口传送多少通信量而定。
在集群中，通过在节点间的网络连接上和在共享磁盘上操作的心跳协议监视资源以便确定每个服务器的可用性。当节点停止接收心跳消息时，它知道另一节点出故障，网络连接上的心跳基于使用Ping和/或RPC(远程过程调用)调用探查从节点的主节点而定。能在专用或公用网络上实现Ping。基于RPC的心跳能使用公用网络发送。
如果主节点没有在特定时间(例如3秒)内从从节点接收响应，那么不能到达从节点，或者从节点有其他的问题。如果主节点停止发送Ping或RPC，从节点假定不能到达主节点或主节点有其他问题。当集群中一个续存的节点确定与一个节点具有连接性或其他问题时，续存的节点必须仍然确定另一节点是真正失效还是简单的不可到达。
如果通过Ping和/或RPC的心跳检测到节点故障，使用通过共享磁盘的心跳来找出出故障节点是真正失效还是仅不可到达。如果失效节点是主节点，从节点之一变为新的主节点。为处理所有网络连接损失的可能性，实现通过共享磁盘(涂写磁盘)的心跳。节点通过涂写，换句话说，通过写入和读取涂写磁盘来交换有关它们的状态的信息。用于主从节点的涂写周期随集群的状态而改变。在正常操作期间，主节点缓慢地，例如以每60秒一次涂写的速率涂写。当主节点丢失从节点时，它更快，例如以每3秒一次涂写的速率涂写。由主节点控制的从节点不涂写。最近丢失主节点的从节点快速地，例如以每3秒一次涂写的速率涂写。既不是主节点也不是从节点的节点缓慢地，例如，以每60秒的速率涂写。
图2示例说明一种实现如何处理网络故障。如果节点具有多个网络端口，以及如果端口之一故障，节点恢复而没有故障转移。图2表示节点1、节点2、...、节点N。节点1具有n1个网络端口，标记为1PIP1、1PIP2、1PIP3、...、1PIPn1。节点2具有n2个网络端口，标记为2PIP1、2PIP2、2PIP3、...、2PIPn2。节点N具有nn个端口，标记为NPIP1、NPIP2、NPIP3、...、NPIPnn。例如，假定节点1具有附加在虚拟服务器上的虚拟IP地址-VIP1。当端口1 PIP1失败时，将VIP1移动到1PIP2，如箭头所示。这将不会导致故障转移，因为它处于相同的节点1中。当1PIP2、1PIP3、...1PIPn-1故障时，会发生相同的情形。然而，当1PIPn1出故障时，在节点1上的所有其他PIP已经出故障后，故障转移发生以及将VIP1移动到节点2中的2PIP1。对其他节点也发生相同的情形；即，虚拟IP地址移动到相同节点内的另一物理端口以及仅当当前节点中的所有物理端口失败时，才发生故障转移。在节点内或以其它方式，能将虚拟IP地址移动到与故障端口相同的子网内的端口或不同子网中的端口。在一种实现中，优先于不同子网中的端口，将选择相同子网中的端口。
在前例子中，虚拟服务器被描述为仅具有一个虚拟IP地址。然而，能将单个虚拟服务器连接到多个虚拟IP地址上，以及节点能具有许多物理和虚拟IP地址。
图3和图4示例说明用于移动虚拟网络接口而不强制故障转移的另一技术。这些图表示运行两组虚拟服务器：VSA1、...VSAn1和VSB1、...、VSBn2的两个节点。在图3中，两个虚拟IP地址VA11和VA12被连接到虚拟服务器VSA1。为简化该图，未示出连接到其它虚拟服务器上的虚拟IP地址。Net1和Net2是不同的子网。客户端305是连接到Net1的客户端以及客户端306是连接到Net2的客户端。HB1和HB2是网络集线器或交换机。客户端306在Net2上与节点A中的虚拟服务器通信。
图4表示当在Net2上的通信故障时所发生的情形。虚拟IP地址VA12被从节点A310迁移到节点B320中的物理端口PIP3。使用网络故障摆脱(failthrough)而不是虚拟服务器故障转移，因为它对客户端损害较少。如前所述，无论何时将虚拟IP地址连接到物理接口上以及当将虚拟地址迁移到另一接口上时，生成免费ARP包。
如图4所示，在Net2故障后，由节点B通过VA12所迁移到的PIP3接收来自客户端306的数据。节点B中的路由软件322通过PIP4，将数据转发到节点A。通过节点B中的PIP4和PIP3，通过PIP1将来自节点A的数据转发到客户端306。
在支持NFS文件系统的一种实现中，将NFS文件锁定存储在共享磁盘中。每个虚拟服务器拥有相应的NFS文件锁定。在故障转移期间，锁的所有权遵循虚拟服务器。因此，虚拟服务器和相应的NFS锁被迁移到健康节点。因此，不需要客户端管理NFS锁。
图5详细阐述在其上构建集群的存储基础结构。节点700、702、...、770是集群的节点。这些节点能部署适当协议的总线适配器以便连接到共享存储总线或结构704上，诸如SCSI、光纤信道判优环、光纤信道结构、InfinBand、iSCSI或其他适当的总线或结构上。多个链路706和708、710和712、720和722将每个节点连接到共享总线或结构704上。这种多个链路允许系统容忍一个链路故障。能提供另外的链路。共享存储单元(多个存储系统)718能是通过至少两个链路714和716，连接到总线或结构704上的一个或多个容错共享存储单元(诸如RAID5或RAI1阵列)。这种基础结构能经受单点故障。多个故障能导致完全丧失到共享存储单元718的访问。
在一种有利实现中，集群中的双光纤信道判优环主机总线适配器连接到双光纤信道判优环。这允许光纤信道目标诸如FC-AL(光纤信道-判优环)RAID(独立磁盘冗余阵列)盒附加在光纤信道判优环主机上。在RAID盒上定义共享存储单元，诸如RAID5(奇偶性)或RAID1(镜像)阵列。
可以从每个集群节点访问共享存储单元718，但通常由用于不同节点的不同路径访问。因此，通过集群范围内的名称(cluster-widename)识别每个节点上的每个共享存储单元是很有利的。这消除了当使用本地设备名时，将设备名绑定到共享存储空间上的困难，本地设备名反映路由信息，因为到相同存储空间的路由在不同集群节点上是不同的。为实现此，使用与每个共享存储单元718有关的独特标识符。适当的标识符是FC RAID控制器的万维ID(WWID)，在该万维ID的基础上，定义共享存储单元718。使用全球可访问名称服务器数据库来将管理器选定的名称与每个共享存储单元的独特标识符相关联。能将数据库存储在任何方便的、全球可访问位置，诸如涂写磁盘或集群外的服务器、但可由所有集群节点访问的位置上。名称服务器由集群节点参考，在它们已经发现共享存储单元并了解共享存储单元的独特标识符后。通过参考名称服务器，集群节点将(能是并且通常是多个)共享存储单元分解成集群范围内的设备名。
因为集群节点具有到共享存储单元的多个路径，通过将I/O(即，输入/输出或数据传送)请求更改到相同的共享存储单元，但通过不同路由，执行负载平衡是很有利的。例如，集群节点700能通过更改链路706和708间的数据传送请求来负载平衡。这通过增加可用来访问共享存储单元的整个带宽，有利于集群节点。
能将该设计配置成能经受单点或多点故障。设计的强壮性由三个因素来定。第一是每个节点和共享存储总线或结构704间的链路数量。第二因素是共享存储总线或结构704和数据存储单元718间的链路数量。对于每对元件间仅两条链路，如图5所示，设计能容许单点故障。对于集群节点中的多个总线适配器，总线适配器能出故障并且到共享存储单元的数据传送请求能以半个带宽性能继续。相关物理接口(诸如电缆)也能出故障。类似地容许电缆的任何单点故障。由于链路数量为2，通过增加链路的数量，能将单点故障容限提高到更高容限。共享存储单元是能容许成员驱动器(member drive)故障的容错RAID阵列。如果使用多个RAID控制器来控制相同的共享存储单元，那么能容许RAID控制器故障。
通过节点所有权锁定保护共享存储单元以便保证专用节点使用率。每个节点知道其它节点的共享存储单元所有权。如果它确定共享存储单元由某个其他节点拥有，其将共享存储单元标识为在那个节点上不可用。
存储抽象，诸如虚拟存储技术允许节点使虚拟存储单元跨越多个共享存储单元。这提高容错以及性能。使用多个共享存储单元，在节点上创建虚拟存储单元。这些虚拟存储设备能跨越由不同存储控制器控制的多个共享存储单元，以及支持有效数据保护和数据传送性能特征。虚拟存储设备能是级联、镜像或带状的多个共享存储单元。
级联提供的优点是容量扩展。当共享存储单元与另一共享存储单元级联时，当第一共享存储单元满时，使用第二共享存储单元。
通过带状的共享存储单元，在各种成员共享存储单元中交替顺序I/O请求。带状虚拟存储设备提供扩展和性能。因为在不同共享存储单元上并行分配数据传送请求，与使用单个共享存储单元相比，节点经历更高吞吐量。
通过2个不同共享存储单元的虚拟存储镜像(RAID 1)，在每个成员共享存储单元上加倍I/O操作。通过以预定最低寻道时间从成员进行读取，增强来自镜像的读取操作。当确定镜像损坏以及正确地替换损坏的成员时，镜像同步是自动的。镜像虚拟存储设备通过容许完全损失共享存储单元来提供额外的容错层。通过部署镜像虚拟存储设备，集群的容错性能增加两倍。
图6示例说明根据本发明的高可用性系统的初始化。在步骤1100，系统集群中的所有节点被配置成指向将用作涂写磁盘的相同的共享存储单元。在步骤1101，分配一个节点以便初始化涂写磁盘。初始化涉及从配置文件提取数据。在步骤1102，在一个节点中启动高可用性软件。该节点变为集群的主服务器。在步骤1103，在所有其他节点上启动高可用性软件。这些节点是集群中的从节点。在步骤1104，主节点将虚拟服务器分配给从节点。如果需要的话，能手动完成这一步骤。
图7表示具有多个网络端口的节点如何检测和处理网络故障。如现在将描述的，其通过测试其每一个端口来完成。在步骤1200，节点使用正测试的端口，以频繁间隔(诸如每3秒)向先前可达的外部端口发送Ping包。进行ping的频率是可配置的。在判定步骤1202，节点确定在预定等待时间(诸如250msec(毫秒))内是否接收到对Ping的响应。等待时间是可配置的。如果接收到响应，在步骤1201，将正测试的端口标记为好的。否则，在步骤1203，节点已知的可达外部IP地址被划分成组。组中的地址总数是可配置的。在步骤1204，一次一组地将Ping消息发送到每个组的地址。这不是使用广播完成的，因为广播更昂贵。在判定步骤1205中，节点确定在等待时间内是否达到组中的任一地址。如果到达一个，在步骤1201，将正测试的端口标记为好的并继续执行。如果没有到达所有组中的任何地址，在步骤1206中继续执行。在步骤1206，发送广播消息。在判定步骤1207，如果在等待时间内接收到任一响应，将正测试的端口标记为好的以及在步骤1201继续执行。否则，节点断定正测试的端口状况不良，以及在步骤1208，将该端口标记为损坏。
在判定步骤1302，节点确定在节点中是否有健康的网络端口。如果有，在步骤1304，故障节点的虚拟地址被迁移到健康网络端口。否则，在步骤1303，请求故障转移到集群中的另一节点。
对节点已经标记为好的每个物理端口，执行图7的过程。
网络端口的故障仅是调用故障转移的可能理由的一个。能导致故障转移的其他事件包括节点或存储系统的一个中的硬件故障、电源故障、节点和存储系统间的链路中的故障、存储总线或结构中的不可恢复故障，以及共享存储单元和存储总线或结构间的链路中的故障。也能手动地启动故障转移。在校正导致故障转移的问题后，能执行手动故障恢复命令以便将虚拟服务器迁移到它们的原始节点。
例如，如果由于任何原因，包含文件系统的共享存储单元不能由节点访问(例如，关于在图5中示例说明的特定结构中的节点700，由于节点和单元间的连接完全断开，诸如链路706和708的故障)，那么使包含不可访问文件系统的虚拟服务器迁移到能访问存储单元，因此能访问文件系统的另一物理节点，如果这种替换节点存在的话。
图8表示当节点中的虚拟服务器在其迁移到另一节点前关闭时执行的步骤。在这一例子中，虚拟服务器具有NFS文件系统和CIFS文件系统。在步骤1401，断开属于虚拟服务器的所有虚拟接口。在步骤1402，取消初始化(de-initialize)所有NFS共享。在步骤1403，执行NFS锁定清除。在步骤1404，取消初始化虚拟CIFS(公用因特网文件系统)服务器和共享。在步骤1405，取消安装(un-mount)属于虚拟服务器的所有文件系统。
图9示例说明调用虚拟服务器所需的步骤。再次，在这一例子中，虚拟服务器具有NFS文件系统和CIFS文件系统。在步骤1501，节点安装属于故障虚拟服务器的所有文件系统。在步骤1502，调用属于虚拟服务器的虚拟接口。在步骤1503，初始化NFS共享。在步骤1504，执行NFS锁定恢复。在步骤1505，初始化虚拟CIFS服务器和共享。
系统能同时服务于各种文件系统。文件系统由于内部文件系统元数据不一致性会出故障，有时称为文件系统退化。在系统的一种实现中，当检测到退化(通常由文件系统本身来完成)，节点中的软件处理文件系统的修复而不完全中断客户机使用NFS协议访问文件系统。在文件系统退化的情况下，暂时阻塞NFS客户机对文件系统的访问。按其属性，NFS协议会继续向服务器发送请求。在阻塞用于NFS访问的文件系统后，软件防止客户机访问文件系统，然后修复它(例如，通过运行实用程序诸如fsck)。在修复文件系统后，软件使得客户机可再次访问。然后，去除NFS阻塞，以便能再次服务于来自客户机的NFS请求。结果，客户机上的应用会暂时冻结而不会失效，但只要文件系统回到在线，即可恢复。
可以任何方式实现系统的管理配置。例如，在系统节点上或单独个人计算机上运行的应用程序能定义和修改用来控制系统配置和操作的参数。在如上所述实现中，这些参数存储在位于涂写磁盘的配置文件中。然而，配置数据能被存储在任意数量的文件中、数据库中，或者以其它方式，并通过任何适当的装置提供给系统。
在某些方面中，本发明能以实际地嵌入计算机可读存储设备中的、用于由可编程处理器执行的计算机程序产品实现；以及本发明的方法步骤可由执行指令程序的可编程处理器执行，以便通过操作输入数据和生成输出来执行本发明的功能。适当的处理器包括，举例来说，通用和专用微处理器。通常，处理器将从只读存储器和/或随机存取存储器接收指令和数据。适合于实际嵌入计算机程序指令和数据的存储设备包括所有形式的非易失性存储器，包括例如半导体存储器件、磁盘诸如内部硬盘和可移动磁盘、磁光盘以及CD-ROM盘。上述的任何一个可通过ASIC(专用集成电路)来补充或纳入ASIC中。
为提供与用户的交互作用，能在具有用于向用户显示信息的显示设备(诸如监视器或LCD屏)和用户能通过其向计算机系统提供输入的键盘和定点设备(诸如鼠标或跟踪球)的计算机系统上实现本发明的方面。计算机系统能编程为提供图形用户界面，通过该图形用户界面，计算机程序与用户交互作用。
根据特定的实施例描述了本发明。其他实施例在下述权利要求的范围内。例如，可按不同顺序执行本发明的步骤，但仍然能获得所需结果。
