    Abstract: Various embodiments are generally directed to techniques for handling errors affecting the at least partially parallel performance of data access commands between nodes of a storage cluster system. An apparatus may include a processor component of a first node, an access component to perform a command received from a client device via a network to alter client device data stored in a first storage device coupled to the first node, a replication component to transmit a replica of the command to a second node via the network to enable performance of the replica by the second node at least partially in parallel, an error component to retry transmission of the replica based on a failure indicated by the second node and a status component to select a status indication to transmit to the client device based on the indication of failure and results of retrial of transmission of the replica.

    Abstract: Several different embodiments of a segmented object storage system are described. The object storage system divides files into a number of object segments, each segment corresponding to a portion of the object, and stores each segment individually in the cloud storage system. The system also generates and stores a manifest file describing the relationship of the various segments to the original data file. Requests to retrieve the segmented file are fulfilled by consulting the manifest file and using the information from the manifest to reconstitute the original data file from the constituent segments. Modifying, appending to, or truncating the object is accomplished by manipulating individual segments and the manifest file. In further embodiments, manipulation of the individual object segments and/or the manifest is used to implement copy-on-write, snapshotting, software transactional memory, and peer-to-peer transmission of the large file.

    Abstract translation: 描述了分段对象存储系统的若干不同实施例。 对象存储系统将文件分成多个对象段，每个段对应于对象的一部分，并且将每个段单独地存储在云存储系统中。 该系统还生成并存储描述各个段与原始数据文件的关系的清单文件。 通过查阅清单文件并使用清单中的信息来重构构成段中的原始数据文件，来满足检索分段文件的请求。 修改，追加或截断对象是通过操纵各个段和清单文件来实现的。 在另外的实施例中，使用各个对象段和/或清单的操作来实现大文件的写时复制，快照，软件事务存储器和对等传输。

    Abstract: Systems and methods which provide mount catalogs to facilitate rapid volume mount are shown. A mount catalog of embodiments may be provided for each aggregate containing volumes to be mounted by a takeover node of a storage system. The mount catalog may comprise a direct storage level, such as a DBN level, based mount catalog. Such mount catalogs may be maintained in a reserved portion of the storage devices containing a corresponding aggregate and volumes, wherein the storage device reserved portion is known to a takeover node. In operation according to embodiments, a HA pair takeover node uses a mount catalog to access the blocks used to mount volumes of a HA pair partner node prior to a final determination that the partner node is in fact a failed node and prior to onlining the aggregate containing the volumes.

    Abstract: A method, non-transitory computer readable medium, and apparatus that monitors with a passive storage controller a plurality of active storage controllers. A determination is made with the passive storage controller when a failure of one of the active storage controllers has occurred based on the monitoring. Storage device(s) previously assigned to the one of the active storage controllers are remapped to the passive storage controller. A transaction log associated with the one of the active storage controllers is retrieved with the passive storage controller from a transaction log database. Transaction(s) in the transaction log are replayed with the passive storage controller, when the failure of the one of the active storage controllers is determined to have occurred.

    Abstract: The present invention aims at providing a storage system capable of shortening the recovery time from failure while ensuring the reliability of data when failure occurs to a storage device. When failure occurs to a storage device, a recovery processing corresponding to the content of failure is executed for the blocked storage device. The storage device recovered via the execution of the recovery processing is subjected to a check corresponding to the operation status of the storage system or the failure history of the storage device.
