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: Described herein is a system and method for a scalable crash-consistent snapshot operation. Write requests may be received from an application and a snapshot creation request may further be received. Write requests received before the snapshot creation request may be associated with pre-snapshot tags and write requests received after the snapshot creation request may be associated with post-snapshot tags. Furthermore, in response to the snapshot creation request, logical interfaces may begin to be switched from a pre-snapshot configuration to a post-snapshot configuration. The snapshot may then be created based on the pre-snapshot write requests and the post-snapshot write requests may be suspended until the logical interfaces have switched configuration.

Abstract: Described herein is a system and method for retaining deduplication of data blocks of a resulting storage object (e.g., a flexible volume) from a split operation of a clone of a base storage object. The clone may comprise data blocks that are shared with at least one data block of the base storage object and at least one data block that is not shared with at least one data block of the base storage object. The data blocks of the clone that are shared with the base storage object may be indicated to receive a write allocation that may comprise assigning a new pointer to an indicated data block. Each data block may comprise a plurality of pointers comprising a virtual address pointer and a physical address pointer. As such, data blocks of the clone comprising the same virtual address pointer may be assigned a single physical address pointer. Thus, a new physical address pointer is assigned or allocated once to a given virtual address pointer of data blocks of a clone.

Abstract: A system and method for providing a substantially constant-time copy operation for file system objects managed by a storage server begins by generating a snapshot of at least a portion of a data set managed by the storage server. The system then performs a copy operation in the storage server to generate a copy of the data set separate from the snapshot, on a set of block locations containing a predetermined reference value. During the copy operation to generate the copy of the data set separate from the snapshot, the system can receive from a requester a first read request directed to the copy of the data set that the copy operation is to generate. In response to the first data request, the system provides data from the snapshot to the requester by the storage server.
