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 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 a 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 translation: 这里描述了一种用于从基本存储对象的克隆的分离操作中保留所得到的存储对象（例如，灵活卷）的数据块的重复数据删除的系统和方法。 克隆可以包括与基本存储对象的至少一个数据块共享的数据块和不与基本存储对象的至少一个数据块共享的至少一个数据块。 可以指示与基本存储对象共享的克隆的数据块以接收可以包括向指示的数据块分配新指针的写入分配。 每个数据块可以包括包括虚拟地址指针和物理地址指针的多个指针。 因此，可以为包括相同虚拟地址指针的克隆的数据块分配单个物理地址指针。 因此，将新的物理地址指针分配或分配给克隆的数据块的给定虚拟地址指针。
