摘要： A method for caching a block, which includes receiving a request to store the block in a cache and determining whether the cache is able to expand. If the cache is not able to expand, then determining whether evictable blocks are present in the cache and, if evictable blocks are present in the cache determining whether a total size of the evictable blocks is greater than or equal to a size of the block, evicting a sufficient number of the evictable blocks from the cache and storing the block in the cache, if the total size of the evictable blocks is greater than or equal to the size of the block, and activating a cache throttle, if the total size of the evictable blocks is less than the size of the block.

摘要： The invention relates to a system that includes a file system configured to create a snapshot of a hierarchical block tree (HBT) and a storage pool. After the snapshot has been created, the storage pool includes a snapshot, where the snapshot includes a copy of a first version of a root block and the HBT, where the HBT includes a second version of the root block. Further, the copy of the first version of the root block is created prior to overwriting the first version of the root block with the second version of the root block, the second version of the root block comprises references to a first block and a second block, and the copy of the first version of the root block comprises a reference to the first block and no reference to the second block.

摘要： A method for caching a block of data. The method including receiving a request to store the block and determining whether an active cache is able to expand. If the active cache is able to expand, then expanding the active cache to obtain an expanded active cache, and storing the block in the expanded active cache. If the active cache is not able to expand, then determining whether evictable blocks are present in the victim cache. If evictable blocks are present in the victim cache, then evicting a sufficient number of the evictable blocks from the victim cache to facilitate storing the block in the active cache, where the evictable blocks in the victim cache are compressed.
摘要翻译： 一种用于缓存数据块的方法。 该方法包括接收存储块的请求并确定活动高速缓存是否能够扩展。 如果活动缓存能够扩展，则扩展活动缓存以获得扩展的活动高速缓存，并将该块存储在扩展的活动高速缓存中。 如果活动缓存不能扩展，则确定可缓存块是否存在于受害缓存中。 如果受害者缓存中存在可消除的块，则从受害者缓存中驱逐足够数量的可排除块，以便于将块存储在活动高速缓存中，其中受害缓存中的可驱逐块被压缩。

摘要： A processing device may generate a data encryption key configured to encrypt unique data within a clone of an encrypted data set and associated with a set of transaction identifiers of a transaction based file system. The processing device may further wrap the data encryption key with a wrapping key, create a cloned encrypted data set with the data encryption key, and store the wrapped data encryption key with the cloned encrypted data set indexed by at least one of the set of transaction identifiers.

摘要： A method for scrubbing a storage pool. The method includes loading a scrub queue with a number of identifiers corresponding to a number of datasets, selecting a first identifier from the scrub queue, where the first identifier corresponds to a first dataset, initiating a scrubbing of the first dataset. The method further includes, upon receiving an indication of a requirement to pause the scrubbing, pausing the scrubbing of the first dataset, creating a bookmark recording a last location within the first dataset that was scrubbed before pausing the scrubbing of the first dataset, detecting at least one change to a storage pool, and performing a modification in response to detecting the at least one change to the storage pool.

摘要： A system for providing extended file attributes is described. Logically, attributes are supported as files within the file system. In this way, the file system is augmented with an orthogonal namespace of file attributes. According, any file (including attribute files) may have an arbitrarily deep attribute tree associated with it. Access to the attribute values is via file descriptors obtained via a special attribute interface. This logical view of “attributes as files” allows the leveraging of existing file system interface functionality to support the construction, deletion, and manipulation of attributes.
