Abstract
The embodiments relate to performing a write operation in a filesystem. Replica files embedded with respective sets of data are stored are on persistent storage local to replica nodes of the filesystem. The storage includes atomically updating the replica files to the replica nodes. Each set of data has information for self-characterizing each replica file. A map stored at persistent storage local to a remote node is updated. The map maintains information for identifying each replica file stored at each replica node.
