Abstract
A method, apparatus, and system for processing Redundant Array of Independent Disks (RAID) Input/Output (I/O) requests for a plurality of nodes in a cluster is disclosed. A file system request including a byte offset is received. Then, a Physical Extent (PE) row that matches the file system request and a RAID stripe within the identified PE row based on the byte offset is identified. Next, a plurality of RAID I/O requests to be routed to a physical disk is generated. Each of the plurality of the RAID I/O requests includes information associated with the PE and a type of operation. Thereafter, each of the RAID I/O requests is processed based on the information associated with the PE and the type of operation.
