摘要： A method for coordinating access to a storage volume between several hosts, each of which has an associated log, may involve: one of the hosts requesting permission from a coordinator to perform a write to a region of the storage volume; the host storing write data for the write to an associated log; and the coordinator sending a response granting permission to perform the write to the host, where the response indicates whether an old version of data in the region of the storage volume should be relocated to a COW (Copy On Write) snapshot volume. The host may signal completion of the write to an application that initiated the write prior to performing the write to the region of the storage volume and subsequent to both storing the write data to the associated log and receiving the response from the coordinator.

摘要： Systems and methods for I/O fencing in a shared storage environment are provided. Prior to initiating an I/O request, when feasible, the current time from a local timer is compared to the current state of an interval obtained for the target device. As a result, a device reset occurring while the interval is viable does not arbitrarily end a multiphase I/O operation. However, a device reset occurring once the lease has expired results in a delay or termination of the multiphase I/O operation. As a result, multiphase I/O operations from initiating hosts that have lost contact with the shared storage environment are not allowed to corrupt the shared storage devices.
摘要翻译：提供了共享存储环境中I / O防护的系统和方法。在启动I / O请求之前，如果可行，将从本地定时器的当前时间与目标设备获得的间隔的当前状态进行比较。结果，间隔可行时发生的器件复位不会任意地结束多相I / O操作。然而，一旦租赁过期，设备复位就会导致多相I / O操作的延迟或终止。因此，发起主机与共享存储环境失去联系的多相I / O操作不允许损坏共享存储设备。

摘要： A method, system, and computer program product for adaptively implementing capabilities of a logical volume. If a particular capability is an inherent attribute of an existing storage device, the existing storage device is chosen to implement the volume. If the particular capability is not an inherent attribute of an existing storage device, one or more storage devices are selected and configured to provide the capability. If a capacity is requested for the logical volume and a storage device provides only a portion of the capacity, multiple storage devices having the capability are combined to provide the requested capability and capacity.

摘要： A method involves: detecting a storage resource indication within a workflow request and, in response to the storage resource indication, generating an availability indication. The storage resource indication indicates a storage resource (e.g., by directly or indirectly identifying or selecting the storage resource). The availability indication indicates that the indicated storage resource is not available for subsequent workflow requests. The availability indication is generated prior to allowing the consumer that generated the workflow request to use the storage resource. The workflow request can include a request to allocate a logical storage structure (e.g., a volume or logical disk). The logical storage structure is allocated in response to the workflow request. If the workflow request is denied or expires, the logical storage structure is deleted.

摘要： A method, system, computer system, and computer-readable medium for maintaining up-to-date, consistent copies of primary data without the need to replicate modified data when the data were modified as a result of an operation that is not an application-driven write operation captured during replication. Selected storage management operations are performed on the primary and secondary data stores at points in time when the data are the same to ensure that the data stored within the data stores remain consistent. These selected storage management operations include operations that produce modified data stored in the primary data store, where a portion of the modified data are not replicated to a secondary node. Other types of storage management operations are selected to be performed on both the primary and secondary data stores, where the operations do not directly change data in the primary data store, but may affect data stored in the primary data store.

摘要： In distributed storage environments, nodes may send replicated writes for temporal volumes and may be configured to request on-demand consistency intervals in order to allow multiple nodes to transition between timestamps for temporal data in a uniform and coordinated manner. In response to a request from a node for a consistency interval transition, a consistency interval coordinator may end a current consistency interval and start another and may provide coordination to various nodes to enable the nodes to transition from one timestamp to another, and thus from one temporal version to another, while prevent data corruption or inconsistency between the temporal versions. Additionally, periodic consistency intervals may be utilized to provide consistent and coordinated transitions between temporal timestamps. In some embodiments, replicated writes including temporal timestamp information may be stored persistent spillover logs allowing offline updating and versioning of data to temporal volumes.
摘要翻译：在分布式存储环境中，节点可以发送用于时间卷的复制写入，并且可以被配置为请求按需一致性间隔，以便允许多个节点以均匀和协调的方式在时间数据的时间戳之间转换。响应于来自节点的用于一致性间隔转换的请求，一致性间隔协调器可以结束当前的一致性间隔并启动另一个间隔，并且可以向各个节点提供协调以使节点能够从一个时间戳转换到另一个时间戳时间版本到另一个，同时防止数据损坏或时间版本之间的不一致。另外，可以利用周期性一致性间隔来提供时间时间戳之间一致和协调的转换。在一些实施例中，包括时间时间戳信息的复制的写入可以是存储的持久性溢出日志，允许将数据离线更新和版本化到时间量。

摘要： Various systems and methods for performing coordinated distributed write logging are provided. A method may involve one of several hosts, each of which has an associated log, requesting permission to perform a write to data in a storage volume from a coordinator. The coordinator coordinates access to the storage volume between the hosts. Prior to receipt of a response from the coordinator granting permission to perform the write to the storage volume, the host may initiate logging the write data for the write to a respective log. The host may signal completion of the write to an application that initiated the write in response to both logging the write data to the respective log and receiving the response from the coordinator. The host may perform one or more underlying block operations to update the storage volume according to the write subsequent to signaling completion of the write to the application that initiated the write.
