摘要： A server of an elastic computing cloud system includes a block device driver apparatus and at least a block device service apparatus. The server implements a hot deployment for a storage service, such that an upgrade of the storage service may be performed without interrupting the storage service. The block device driver apparatus maintains a waiting queue and a pending queue for each storage service. In response to determining a storage service will perform an upgrade, the block device driver apparatus stops processing data write/read requests that are maintained in the pending queue for the service, and puts the data write/read requests that are currently processed in the pending queue back to the waiting queue for re-dispatching, thus realizing completion of processing the upgrade of the storage service in the elastic computing cloud system without interrupting the storage service.

摘要： The present disclosure introduces a method and an apparatus of shrinking virtual hard disk image file. The present techniques search a garbage data block in a file and revise a record of the garbage data block in a block allocation table (BAT). The file includes one or more data blocks and a BAT that records information of each data block. The garbage data block is a data block that does not store effective data. The present techniques move an effective data block subsequent to the garbage data block, revise a record of the effective data block in the BAT after the moving, and shrink a size of the file after the movement.
摘要翻译：本公开引入了缩小虚拟硬盘映像文件的方法和装置。本技术在文件中搜索垃圾数据块并修改块分配表（BAT）中的垃圾数据块的记录。该文件包括一个或多个数据块和记录每个数据块的信息的BAT。垃圾数据块是不存储有效数据的数据块。本技术移动垃圾数据块之后的有效数据块，在移动之后修改BAT中的有效数据块的记录，并且在移动之后缩小文件的大小。
