Abstract
Embodiments of the present disclosure relate to a method, an apparatus and a computer program product of recovering from a failure of a first node within a data storage system by receiving notice from the data storage system that the first node has failed; and restoring the first node based on a heat map of data I/O activity to the first node.
Claims15
A method of recovering from a failure of a first node within a data storage system, the method comprising:
- receiving notice from the data storage system that the first node has failed;
- and
- restoring the first node by creating a restored first node, from the data storage system, based on a heat map of data I/O activity to the first node, wherein the restored first node replaces the first node, wherein restoring the first node comprises:
- analyzing the heat map to determine which portions of data are most active;
- and
- restoring first the most active data to the restored first node.
A system recovering from a failure of a first node within a data storage system, comprising at least one hardware processor;
- and at least one memory comprising computer program codes, wherein the at least one memory and the computer program codes are configured, with the at least one processor, configured for:
- receiving notice from the data storage system that the first node has failed;
- and
- restoring the first node by creating a restored first node, from the data storage system, based on a heat map of data I/O activity to the first node, wherein the restored first node replaces the first node, wherein restoring the first node comprises:
- analyzing the heat map to determine which portions of data are most active;
- and
- restoring first the most active data to the restored first node.
A computer program product, the computer program product being embodied in a computer-readable non-transitory medium and includes a computer readable program instruction, and when being loaded into an apparatus, the computer-readable program instruction performs
- receiving notice from the data storage system that the first node has failed;
- and
- restoring the first node by creating a restored first node, from the data storage system, based on a heat map of data I/O activity to the first node, wherein the restored first node replaces the first node, wherein restoring the first node comprises:
- analyzing the heat map to determine which portions of data are most active;
- and
- restoring first the most active data to the restored first node.
