摘要： Various embodiments of systems and methods are disclosed for tracking valid regions of a working volume. State information identifies which regions of the working volume are currently valid. When the volume is created, the state information can be initialized to a value that identifies all regions of the volume as being invalid. The invalid regions do not need to be synchronized, since there will not be any need to reconstruct the data within those regions to a particular value. Accordingly, volume initialization, which synchronizes redundant data (e.g., RAID parity or a mirrored copy) with application data in the invalid regions, can be delayed. As the volume is accessed by an application, the redundant data associated with the regions being accessed is synchronized, and the state information is updated to indicate that those regions are valid.

摘要： A method may involve: an application executing on a host initiating a write to a stripe in a storage volume; in response, the host requesting permission from a coordinator to perform the write to a set of data (e.g., a stripe or other group of data from which redundant information is calculated according to a RAID protocol) in a storage volume; prior to receiving permission to write to the storage volume from the coordinator, the host initiating storage of write data associated with the write to an associated one of a plurality of logs; the host waiting before performing the write to the storage volume; and, if one or more additional writes targeting the same set of data (e.g., the same stripe) are initiated while waiting, the host combining redundant information (e.g., parity) calculations for the writes into a single redundant information calculation.

摘要： A virtual copy of data stored in a first memory is created in a second memory. Creating the virtual copy includes, in one embodiment, creating first and second tables in memory each one of which comprises a plurality of multibit entries. Each entry of the first table corresponds to a respective memory region of the first memory. Each entry of the second table corresponds to a respective memory region of the second memory. The first bit of the first and second tables indicates whether the corresponding memory region of the first and second memories, respectively, contains valid data. The second bit of the first and second tables indicates whether data in the corresponding memory region of the first and second memories, respectively, has been modified since the creation of the first and second tables, respectively.

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： 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.

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： Configuration data, such as options a file system accessed by a host system, may be stored on the storage device storing the file system. File system configuration data may be stored in a file of the file system or in a private storage area configured for storing file system configuration data. A host may access the file system configuration data and subsequently may access the file system according to the file system configuration data. Additionally, different versions of file system configuration data may be stored and different hosts accessing the file system may read and use different versions of the file system configuration data based upon the type or context of the host accessing the file system. Storing file system configuration data with the file system data, or on the same storage device, may allow context dependent options to be provided to various hosts accessing the file system data.
摘要翻译：诸如由主机系统访问的文件系统的选项的配置数据可以存储在存储文件系统的存储设备上。文件系统配置数据可以存储在文件系统的文件中或存储在用于存储文件系统配置数据的专用存储区域中。主机可以访问文件系统配置数据，随后可以根据文件系统配置数据访问文件系统。此外，可以存储不同版本的文件系统配置数据，并且访问文件系统的不同主机可以基于访问文件系统的主机的类型或上下文来读取和使用不同版本的文件系统配置数据。使用文件系统数据或同一存储设备存储文件系统配置数据可能允许向访问文件系统数据的各种主机提供与上下文相关的选项。
