Abstract:
Accessing objects in an erasure code supported object storage environment including receiving, from a requesting entity, a read request for an object stored in the object storage environment; identifying, using a placement data structure, an object fragment location of a first object fragment of the object; calculating, based on a filesystem root inode number and the object fragment location, a first inode address for the first object fragment of the object, wherein the first inode address identifies a location on a first storage node; reading, using the first inode address, the first object fragment and an inode structure, wherein the inode structure for the first inode address comprises a second inode address for a second object fragment of the object; reading the second object fragment using the second inode address, wherein the second inode address identifies a location on a second storage node; and providing, to the requesting entity, a reconstructed object comprising the first object fragment and the second object fragment.
