Abstract
Embodiments of method and system are directed to a best effort method to reconstruct corrupt files from available nodes or tiers and heal or repair the corrupt files within a cluster of nodes. The method looks for the existence of fingerprints of the lost segments in available tiers on the nodes or across nodes within a cluster. The method discovers the copies of these missing segments, creates an Lp tree referring these discovered segments and creates a virtual file in the namespace. The file is then moved to the destination tier where the corruption exists, thus healing the corruption.
