    Abstract: File system-awareness of ghosting performed by one or more tiering engines allows a file system to receive and store metadata indicating an identifier of the tiering engine ghosting the file extents and a storage location of the ghosted file extents for later use by the tiering engine. The file system is able to receive and process requests to read and write to a file having ghosted extents.

    Abstract: 一种不常用数据的识别方法,包括:根据第一扫描规则扫描存储空间中的文件,根据扫描的文件生成文件集合(S101);对于文件集合中的每个文件,获取文件的最后访问时间点(S102);获取文件的文件属性,查询与文件属性对应的不常用文件识别条件(S103);若文件的最后访问时间点满足不常用文件识别条件,识别出文件为不常用文件(S104)。相应的,还公开了一种终端。采用该方法,能准确识别不常用的文件。

    Abstract: To identify objects shared by entities and to identify free space in nonvolatile storage, a computer system uses a probabilistic data structure which tests whether an element is a member of a set. Such probabilistic data structures are created for entities in the storage system that share objects. The probabilistic data structure for an entity represents the objects used by that entity. When an entity is deleted, each object used by that entity is compared to the probabilistic data structures of other entities to determine if there is a likelihood that the object is used by one or more of the other entities. If the likelihood determined for an object is above an acceptable threshold, then the object is not deleted. If the likelihood determined for an object is below the set threshold, then the object can be deleted and the corresponding storage locations can be marked as free.

    Abstract translation: 为了识别由实体共享的对象并识别非易失性存储器中的空闲空间,计算机系统使用概率数据结构来测试元素是否是集合的成员。 这种概率数据结构是为共享对象的存储系统中的实体创建的。 实体的概率数据结构表示该实体使用的对象。 当删除实体时,将该实体使用的每个对象与其他实体的概率数据结构进行比较,以确定是否存在该对象被一个或多个其他实体使用的可能性。 如果为某个对象确定的可能性高于可接受的阈值,则该对象不会被删除。 如果为某个物体确定的可能性低于设定的阈值,则该物体可以被删除,相应的存储位置可以被标记为空闲。

    Abstract: Representative embodiments set forth herein disclose techniques for implementing dynamic file system volumes that can share storage space with other file system (FS) volumes within the same partition / storage device. According to some embodiments, techniques are disclosed for establishing an FS volume within a container. According to other embodiments, techniques are disclosed for handling input / output (I/O) requests across different FS volumes. According to yet other embodiments, techniques are disclosed for efficiently establishing, within a storage device, an FS volume from an image of the FS volume.
