Restoration of Erasure-Coded Data Via Data Shuttle in Distributed Storage System

A non-transitory machine-readable medium having stored thereon instructions for performing a method comprising machine-executable code that, when executed by at least one machine, causes the at least machine to:

• detect that a first data shuttle device is communicatively coupled to a first node of a distributed storage environment comprising the first node and a second node;
• generate, from a first erasure-coded data portion stored on the first node, first restoration data on the first data shuttle device responsive to detecting that the first data shuttle device is communicatively coupled to the first node;
• detect that the first data shuttle device or a second data shuttle device is communicatively coupled to the second node;
• generate, from a second erasure-coded data portion stored on the second node, second restoration data on the first or second data shuttle device communicatively coupled to the second node, wherein the second restoration data is generated responsive to detecting that the first or second data shuttle device is communicatively coupled to the second node;
• and
• restore a third erasure-coded data portion at a third node of the distributed storage environment subsequent to at least one of the first or second data shuttle devices being transported from at least one of the first or second nodes to a location of the third node, wherein the third erasure-coded data portion is generated via an erasure-coding process from at least one of the first restoration data stored on the first or second data shuttle device or the second restoration data stored on the first or second data shuttle device.

A computing system comprising:

• a memory containing machine readable medium comprising machine-executable code having stored thereon instructions for performing a method;
• at least one processor coupled to the memory, the processor configured to execute the machine-executable code to cause the at least one processor to:
• detect that a first data shuttle device is communicatively coupled to a first node of a distributed storage environment comprising the first node and a second node,
• generate, from a first erasure-coded data portion stored on the first node, first restoration data on the first data shuttle device responsive to detecting that the first data shuttle device is communicatively coupled to the first node,
• detect that the first data shuttle device or a second data shuttle device is communicatively coupled to the second node,
• generate, from a second erasure-coded data portion stored on the second node, second restoration data on the first or second data shuttle device communicatively coupled to the second node, wherein the second restoration data is generated responsive to detecting that the first or second data shuttle device is communicatively coupled to the second node, and
• restore a third erasure-coded data portion at a third node of the distributed storage environment at a location of the third node, wherein the third erasure-coded data portion is generated via an erasure-coding process from at least one of the first restoration data stored on the first or second data shuttle device or the second restoration data stored on the first or second data shuttle device.
