    摘要: A file system receives a request to set a capacity guarantee for a virtual volume associated with a logical aggregation of physical storage. In response, the file system sets the capacity guarantee to indicate that the logical aggregation of physical storage is to provide a specified amount of space to the virtual volume. The amount of space provided to the virtual volume may be based, at least in part, on a guarantee type. The guarantee type may include, for example, volume, file, none, or partial.

    摘要: A system and method persistently stores lock state information associated with a file system within a storage system. Received operations that modify lock state information are stored in a non-volatile log (NVLog) within a non-volatile random access memory (NVRAM) of the storage system. During a consistency point (CP), entries from the NVLog are committed to a lock file. In the event of an error condition, lock state information may be recovered from the lock file, thereby enabling rapid reconstruction of the lock state prior to the error condition.

    摘要: An apparatus and method for managing of common storage in a storage system is disclosed. In one embodiment, a storage system receives a request to set a space reservation for a volume associated with a logical aggregation of physical storage. In response, the storage system sets the space reservation to indicate that the logical aggregation of physical storage is to provide a specified amount of space to the volume. In one embodiment, space within the logical aggregation of physical storage is automatically reclaimed to set a delayed space reservation if the amount of unused space within the logical aggregation of physical storage is insufficient to set the space reservation. In one embodiment, the volume is either a space-reclaimable volume or a non-space-reclaimable volume. Other embodiments are described and claimed.
