Method and apparatus for distributed erasure encoding

A system comprising:

• one or more processors;
• and
• at least one computer-readable storage medium having stored therein instructions which, when executed by the one or more processors, cause the system to:
• generate a plurality of virtual redundant array of independent disk (vRAID) stripes, each of the plurality of vRAID stripes including a segment having a plurality of data, each of the plurality of data including metadata, the metadata including a checksum of a corresponding data of the plurality of data;
• distribute the segment of each of the plurality of vRAID stripes over a plurality of virtual nodes, the plurality of virtual nodes including a plurality of data chunks and at least one parity chunk;
• map at least one of logical files, volumes, or objects to the plurality of data chunks and the at least one parity chunk of the plurality of vRAID stripes to avoid write-hole issues;
• and
• verify data integrity of the corresponding data of the plurality of data using the checksum of the corresponding data.

A non-transitory computer-readable storage medium comprising:

• instructions stored on the non-transitory computer-readable storage medium, the instructions, when executed by one or more processors, cause the one or more processors to:
• generate a plurality of virtual redundant array of independent disk (vRAID) stripes, each of the plurality of vRAID stripes including a segment having a plurality of data, each of the plurality of data including metadata, the metadata including a checksum of a corresponding data of the plurality of data;
• distribute the segment of each of the plurality of vRAID stripes over a plurality of virtual nodes, the plurality of virtual nodes including a plurality of data chunks and at least one parity chunk;
• map at least one of logical files, volumes, or objects to the plurality of data chunks and the at least one parity chunk of the plurality of vRAID stripes to avoid write-hole issues;
• and
• verify data integrity of the corresponding data of the plurality of data using the checksum of the corresponding data.
