摘要： Methods, systems, and computer storage mediums including a computer program product method for formatting storage volumes are provided. One method includes creating a storage volume including a global counter and partitioned into multiple storage segments including a segment counter and partitioned into multiple stripes, wherein the global counter and each segment counter match at an initial time. The method further includes receiving a command to write data to a first stripe, comparing a first segment counter associated with the segment, determining if the segment and global counters match, and re-initializing first metadata associated with the segment to indicate the first segment requires formatting if the counters do not match. One system includes a processor for performing the above method and one computer storage medium includes a computer program product configured to perform the above method.

摘要： Various embodiments for initializing metadata in a computing storage environment by a processor. A Release Generation Number (RGN) is associated with a volume, and an RGN is associated with a metadata track. Upon a release of storage space in the volume, the RGN associated with the volume is incremented. Upon an initialization of the metadata track, the RGN associated with the metadata track is updated to be consistent in generation with the RGN associated with the volume. Upon an access of the metadata track, the RGN of the metadata track is compared against the RGN of the volume, and the metadata track is initialized if a match is not found.

摘要： Various embodiments for storage initialization and data destage in a computing storage environment are provided. At least a portion of data on a storage device is initialized using a background process, while one of simultaneously and subsequently destaging the at least the portion of the data to the storage device using a foreground process is performed. A persistent metadata bitmap, adapted to indicate whether the at least the portion of the data has been initialized, is staged to cache, the cache operable in the computing storage environment. The background process maintains a volatile bitmap indicating a status of the initialization of the at least the portion of the data in direct correspondence to the metadata bitmap. As the background process initializes the at least the portion of the data, an applicable bit on the persistent metadata bitmap is cleared and a corresponding bit is set on the volatile bitmap.

One method includes creating a storage volume including a global counter and partitioned into multiple storage segments including a segment counter and partitioned into multiple stripes, wherein the global counter and each segment counter match at an initial time. The method further includes releasing the storage segments prior to completely reformatting the storage volume and subsequently incrementing the global counter such that the global counter and each segment counter no longer match at a subsequent time. The method further includes enabling a user to write data to the storage segments prior to completely reformatting the storage volume in response to incrementing the global counter. One system includes a processor for performing the above method and one computer storage medium includes a computer program product configured to perform the above method.
