Abstract
Embodiments of method and system are directed to a best effort method to reconstruct the corrupt files from available nodes or tiers and heal or repair the corrupt files. 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.
