Abstract:
Systems, methods, and computer readable media for tracking storage pool reservations are disclosed. According to one aspect, the subject matter described herein includes a system for tracking storage pool reservations. The system includes a storage entity having data storage space for storing data, the data storage space being divided into a plurality of slices. The system also includes one or more portions of non-volatile memory, different from the data storage space, for storing slice reservation statistics and information about requests that affect slice reservation statistics, wherein storing information in the portion of non-volatile memory is an atomic operation. The system further includes a control module for receiving a request that affect slice reservation statistics, storing information about the request in the portion of non-volatile memory, performing the request, and updating the slice reservation statistics and clearing the information about the request in the portion of non-volatile memory.
