Abstract
A method for rebuilding data, comprising: obtaining, from a metadata node, a source file data layout for a source file and a target file data layout for a target file, wherein the source file is associated with a degraded mapped RAID group and the target file is associated with a new mapped RAID group; generating, by the client application node, a plurality of input/output (I/O) requests to read a portion of the data associated with the source file using the source file data layout; obtaining, in response to the plurality of I/O requests, the portion of the data associated with the source file; rebuilding a second portion of the data associated with source file using the portion of the data; and initiating, storage of at least the second portion of the data associated with the source file in the storage pool using the target file data layout.
