Abstract
Technology is provided for updating a data set at a data storage system. In an example storage system, the system stores a data set in a plurality of data storage devices. The system stores parity data at a plurality of parity devices. The system receives update data from a client system for a first section of the data set. The system generates updated parity data based on an original version of the first section of the data set and the update data. The system transmits update parity data to the plurality of parity devices. The system receives update notifications from a plurality of parity devices. The system determines that update notifications have been received from at least a threshold number of parity devices in the plurality of parity devices. In response, the system updates the first section of the data set at the leader data storage device.
