Abstract: Example implementations relate to allocating an I/O request. In an example, a demultiplexer may forward an I/O request to a file system instance to which the I/O request belongs. The file system instance may tag the I/O request with a file system instance identifier associated with that file system instance. A volume manager may identify an extent pool to which the I/O request is to be allocated from among a plurality of extent pools of a storage based on the file system instance identifier tagged to the I/O request.

Abstract: Example implementations relate to objects in extents on a storage resource. In an example, an extent identifier is persisted to a storage allocation table, where the extent identifier locates an extent on a storage resource. An extent map tracks which objects in the extent are deallocated. A virtual block address is generated allocating an object to store data. The virtual block address may include a storage allocation table key that locates the extent identifier in the storage allocation table and an extent offset to locate the object within the extent.
