Abstract: A system and method for reallocating block in a checkpointing bitmapped-based file system is provided. The system and method enable blocks to be allocated or reallocated during checkpoints which permits various file system processes to proceed during the checkpointing process. An additional copy of the bitmap is created when the bitmap is being written to disk, thereby enabling these various file system processes to continue to operate on a bitmap during the checkpointing process.

Abstract translation: 提供了一种用于在基于检测点位图的文件系统中重新分配块的系统和方法。 系统和方法使得能够在检查点期间分配或重新分配块，这允许在检查点处理期间进行各种文件系统处理。 当位图被写入磁盘时，会创建位图的附加副本，从而使这些各种文件系统进程能够在检查点处理过程中继续对位图进行操作。
