A data access method and apparatus, where the method includes acquiring a data read request that is for a first disk group and carries a read address, determining a first-stripe location range of the first disk group according to the read address, sequentially reading data from first stripes within the first-stripe location range, setting a data reading result for a first stripe whose data is not successfully read to preset padding data, continuing to read data from a next first stripe until data is read from all the first stripes, and returning a data reading result for each first stripe. Thus the method and apparatus may reduce data loss and shortens access interruption time when data is not successfully read.

Data access method and apparatus

A load balancing method to resolve a problem of load imbalance, where the method includes obtaining first status information of the first device and first status information of the second device, obtaining second status information of the first device and second status information of the second device, calculating a space occupation ratio of the first device and a space occupation ratio of the second device respectively according to the second status information of the first device and the second status information of the second device, determining a balancing policy according to the space occupation ratio of the first device and the space occupation ratio of the second device, and perform scheduling according to the balancing policy to implement load balancing between the first device and the second device.
