摘要： A data access request to a file system is decomposed into a plurality of lower-level I/O tasks. A logical combination of physical storage components is represented as a hierarchical set of objects. A parent I/O task is generated from a first object in response to the data access request. A child I/O task is generated from a second object to implement a portion of the parent I/O task. The parent I/O task is suspended until the child I/O task completes. The child I/O task is executed in response to an occurrence of an event that a resource required by the child I/O task is available. The parent I/O task is resumed upon an event indicating completion of the child I/O task. Scheduling of any child I/O task is not conditional on execution of the parent I/O task, and a state diagram regulates the child I/O tasks.
摘要翻译：对文件系统的数据访问请求被分解成多个较低级的I / O任务。物理存储组件的逻辑组合被表示为一组分层对象。响应于数据访问请求，从第一对象生成父I / O任务。从第二个对象生成子I / O任务，以实现父I / O任务的一部分。父I / O任务被暂停，直到子I / O任务完成。响应于发生子I / O任务所需的资源可用的事件，执行子I / O任务。在指示完成子I / O任务的事件后，将恢复父I / O任务。任何子I / O任务的调度不是执行父I / O任务的条件，而状态图则规定了子I / O任务。

摘要： A method for storing data on a plurality of storage devices of a storage system is disclosed. The data is received as data blocks from a plurality of write requests. The data blocks are saved as buffered data for writing to the storage devices in a single write request. An indication is received indicating the available storage blocks on the plurality of storage devices which are available for writing. The buffered data is associated with selected storage blocks of the storage blocks which are available for writing. The buffered data is written to the selected storage blocks in a single write request.

摘要： A system and method for fast (“warm”) reboot of a file server is provided, which skips certain conventional boot processes when circumstances warrant, in order to reduce server downtime. In particular, time is saved by avoiding a full shutdown of the processor and memory, and by causing the firmware to refrain from a full clearance of the file server memory. Instead, the firmware accesses a retained copy of the storage operating system kernel from a reserved location in the file server memory so that an operative version of the kernel is reestablished at the appropriate address space in memory without requiring a time-consuming read of the kernel image from disk. In addition, other “normal” (cold) reboot operations such as full memory tests, hardware checks and memory zeroing are avoided as appropriate—saving further time in the overall reboot process, while still attaining the desired reinitialization of key applications and functions.
摘要翻译：提供了一种用于文件服务器快速（“暖”）重启的系统和方法，当情况需要时跳过某些常规引导过程，以减少服务器停机时间。特别地，通过避免处理器和存储器的完全关闭以及通过使固件不能完全清除文件服务器存储器来节省时间。相反，固件会从文件服务器内存中的保留位置访问存储操作系统内核的保留副本，以便内存的可操作版本在存储器中的适当地址空间重新建立，而不需要耗时读取内核磁盘映像此外，在适当的情况下，可以避免其他“正常”（冷）重启操作，例如全面内存测试，硬件检查和内存归零，从而节省了整个重新引导过程中的更多时间，同时仍能实现关键应用程序和功能的所需重新初始化。

摘要： A slice manager module, in the operating system of a storage server, manages the virtual slicing of a mass storage device. The slice manager module receives a notification that a mass storage device has been added to an array of mass storage devices coupled to the storage system. The slice manager module reads header information in the mass storage device to determine a format of the mass storage device. If the mass storage device has not been previously sliced, the slice manager module virtually slices the mass storage device into a plurality of slices, where virtually slicing the mass storage device includes specifying an offset in the mass storage device where each of the plurality of slices is located.

摘要： A storage server receives a notification indicating a failure of a mass storage device in a storage array. The storage server determines whether a number of failures exceeds a fault tolerance level of the array and if the number of failures exceeds the fault tolerance level, recovers an address space corresponding to the failed storage device. When recovering the address space, the storage server replaces the failed storage device with a spare storage device having an identifiable pattern stored thereon and determines whether a file system on the storage system can automatically invalidate cached data blocks on the failed storage device.

摘要： A method and system manages ownership information about disks in a storage network without the need for an emulated, partner mode system. The method and system provides for ownership information, including a current owner and a home owner for resources, such as disks, to be stored on each disk in a storage system, as well as to be stored in memory on each storage system node in the network. A further aspect of the invention is a disk homeness application program interface (API), which provides commands that can be utilized by an administrator at a host computer to set, modify and display ownership information about each disk in the cluster. Upon a takeover, any node in the network can takeover one or more disks by reading the ownership information stored on the disks or in the tables.

摘要： A method and system performs a sendhome procedure for giving back resources to a node that had been restored after a takeover of that node's resources is provided. Critical operations that may be running are completed prior to the sendhome process. An ownership module consults information in an ownership table about each resource, e.g. a data container. A data container, such as a root aggregate of the waiting node is identified and sent back first, after which the node is booted. When the node has been successfully booted, the remaining aggregates are sent back one at a time until the full compliment of aggregates has been returned. A veto of the sendhome procedure can be invoked by a subsystem that is performing a critical operation prior to the sendhome of the root aggregate and each individual other aggregate.
